&lt;hr /&gt;
&lt;div&gt;== 5K Hydraulic To Solid Lifter Conversion ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Worried that your 5K hydraulic lifters won&#039;t be any good at high RPM? Many people consider this to be the biggest letdown of the 5K-C engine - other&#039;s say that the lifters are fine to 8000+ RPM. It is pretty much up to you, but many people still advise doing this conversion. (Here we will discuss how to convert Hydraulic Lifters back to Solid Lifters in a 5K-C).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;&#039;&#039;Easiest Solution;&#039;&#039;&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
Well, Luckily for you, We have some very kind people on rollaclub who decided to share some little-known information that the 5K-C actually did come from factory in one vehicle with factory solid lifters! This means that if you can find this part, You won&#039;t have to mess around - just &#039;&#039;&#039;&amp;quot;bolt it on&amp;quot;&#039;&#039;&#039; It was fitted to a Toyota KM36RV-JR Liteace Van with a Toyota Part Number of &#039;&#039;13751-61020-&#039;&#039; this part number cross references to a 3F Landcruiser, So if you can find a 3F Landcruiser engine you&#039;ll have one and a half sets.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
This part is listed on the Toyota EPC (Electronic Parts Catalogue). Here is a screenshot of the EPC page for the 5K Solid Lifter :&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;Many thanks go to Chris and Tony Scott for their research and extensive knowledge that they contributed to finding this part number&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;&#039;&#039;Other Solutions;&#039;&#039;&#039;&#039;&#039;&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;Xany&#039;s KE55 5K Solid Lifters;&#039;&#039; &lt;br /&gt;
&lt;br /&gt;
Ok basically the way we did it was trial and error, As I cant remember the actual measurements of the 5K hydro lifter. Find yourself some calipers and if you have a spare 5K lifter out of the block, measure the length and diameter of the lifter. Once you have that you can bascically just cross reference the measurements with a chev lifter of the same. Most of the chev lifters we found were solids. Once you have found the lifter that matches you&#039;ll then need to try and find some pushrods to fit. As I used a 3K head the pushrods had to be changed from ball - ball ends to ball and cup. I&#039;d heard somewhere that A12 Datsun pushrods are a one peice ball and cup pushrod. So I found some of them and they actually did fit nicely....The only other thing I changed was the rocker gear as the 5K item isnt adjustable because of the hydraulic lifters. I changed to the 4K rocker gear, just remember though that there is 2 different 4K rocker gears, one with long posts and one with short.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Note: This will not work with an original 5K shallow combustion chamber head. You have to be running a taller head from a flat top piston motor (ie. 3k bigport), otherwise the A12 pushrods will be too long.&#039;&#039;&#039; -Felix&lt;br /&gt;

&lt;br /&gt;
* Looking for articles by anyone who has done it the hard way...&lt;br /&gt;
&lt;br /&gt;
edit by AE25 - due to this same question being asked all the time I&#039;d put together a solid lifter conversion FAQ which may be useful here&lt;br /&gt;

&lt;div&gt;Uses T40 and T50 gearboxes on the 2T. W40 and W50 used on the 3T up until 1983 where both the 2T and 3T changed over to the 22 spline T40/T50 (like found in AE86).  Early T box have the shifter positioned at front of tail housing as used in corolla/celica up to late 70&#039;s.  The shifter position changed to the rear of tail housing but still with 20 spline output shaft introduced in the E7 corolla and A4 celica models.  There are some rumors that say the T40 is stronger than the T50 gearbox, I don&#039;t know if this is true?&lt;br /&gt;
13T in the TX50 cresta, TX60/TX67 mark2 had a W45 alloy 4speed.&lt;br /&gt;
A W55 (supra) box can be found behind some jdm TA63 efi 3T-EU and all manual 3tgte in TA63 celica/carina and TT142 corona.&lt;br /&gt;
13T townace have an L40 steel case box with side selectors (column change).&lt;/div&gt;</summary>

&lt;hr /&gt;
&lt;div&gt;There are a few options for adapting a gearbox to a K series motor, So here is a guide is to what is out there..&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[Image:100 1648 Gearboxes.jpg]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;K40/K50 (Toyota Factory 4/5 Speed manual)&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The K40 or K50 gearbox was factory fitted behind 3K/4K/5K motors. They are the most common gearbox in early KE Corollas. TRD gearsets were available for K50 gearboxes.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;T40/T50 (Toyota Factory 4/5 Speed Manual)&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The T50 gearbox is a lot stronger than the K50 gearbox and is a split casing design. You can still purchase close ratio gearsets for the T50 gearboxes through TRD and also Quaife. The T40 or T50 gearbox can be adapted to a K series motor with a K-T Bellhousing, &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;The K-T Bellhousing came in a few different forms...&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1. Cable clutch K-T Bellhousing, Extremely rare, Easier to install in earlier KE Corollas as you don&#039;t need to install a hydraulic clutch (Pictures courtesy of Xany and tojo2).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
This is a 2T bellhousing.. who put this in here???&lt;br /&gt;
[[Image:Gearboxnetresize04.jpg]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
2. Hydraulic clutch K-T Bellhousing, Rare, Requires hydraulic clutch setup to be installed. (Off KA67 5K T40/Carina, KT14x series Corona)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
3. TRD Upright bellhousing, Like the Holy Grail if you can find one, Cable clutch, Designed to allow for the positioning of an upright K motor. If you have one of these please send me some pictures so I can upload them here, Also your address would be great so I can come and steal it :)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
CLUTCH FOR K-T50:&lt;br /&gt;
Although the K-T50 bellhousing in any form is very rare, nearly every clutch manifacturer make a kit for it. When looking for a ke20-70 clutch kit you may be asked &amp;quot;is it a 19 or 21 spline?&amp;quot; &lt;br /&gt;
&lt;br /&gt;
All post ke20 K40 and K50 gearboxes have a 19 spline input shaft, with a 180mm diametre clutch plate. Hence the clutch dimentions are 180x21.6x19T - where 21.6mm is the input shaft diametre. These are listed as &amp;quot;most 4 &amp;amp; 5 speeds&amp;quot;.&lt;br /&gt;
This is the exedy listing for a K40/50 clutch....&lt;br /&gt;
http://www.exedy.com.au/SpecSheet.aspx?SpreadsheetRowId=40330&lt;br /&gt;
&lt;br /&gt;
The T50 box has a 24.1mm input shaft with 21 splines, this is the 21 spline kit you may be asked if you have. It still bolts to a stock 3k/4k 180mm flywheel, hence the clutch dimentions are 180x24.1x21T. Commonly referred to as &amp;quot;some 5 speeds&amp;quot;. Here is Exedy&#039;s listing for the K-T....&lt;br /&gt;
http://www.exedy.com.au/SpecSheet.aspx?SpreadsheetRowId=40331&lt;br /&gt;
&lt;br /&gt;
You may also notice that between different clutch manifacturers the middle number in the dimentions (input shaft diametre) may be different. For example PBR list the K-T50 kit as 180x28.3x21T. This is because they measure the diametre of the shaft in the vallies, whereas say Exedy measure it on the peaks of the spline.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
GEARBOX SELECTION - Which one to use?&lt;br /&gt;
There are a few different type of T50 gearboxes, and you need to be selective on which one you use for a K-T.&lt;br /&gt;
Shifter position:&lt;br /&gt;
TA22 &amp;amp; T18 T50&#039;s share a &amp;quot;ke30-55&amp;quot; shifter position. The AE86 and AE71 T50&#039;s have a &amp;quot;ke70&amp;quot; shifter position.&lt;br /&gt;
TA22 &amp;amp; T18 T50&#039;s both also have a 20 spline output shaft, just like a ke20-70 corolla. The gearbox is also the same length so there is no tailshft mods required to use one! The later (AE86/AE71)ones are 22 spline output and will require the tailshaft yoke to be swapped.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Toyota W50 (Toyota Factory 5 Speed Manual)&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The W#0 (W40/W50) gearbox will fit if you use a K-L (L40) van bellhousing from a KM20-36 Liteace.&lt;br /&gt;
This bell housing will bolt up to 4x of the 7x bolt holes on a W40 or W50 celica STEEL CASE gearbox, however you will need to grind a small amount out of the back of the bell housing to clear a &amp;quot;welse plug looking thing&amp;quot; on the gearbox - see the below link for pictures of this. I have mine bolted to (see below pic) an RA40 celica W50.&lt;br /&gt;
&lt;br /&gt;
CLUTCH and FLYWHEEL:&lt;br /&gt;
There is only one option when it comes to clutches &amp;amp; flywheels for this GB combo. You need to use the KM20-36 (beit 4k or 5k) flywheel, clutch fork, throwout bearing retainer, and clutch kit. The flywheel on a litace has the same overall diametre as a corolla one, however it has a bigger 200mm clutch plate surface. The W50 input spline is the same as a liteace one so it all then matches up. Clutch dimentions are 200x29.8x21T and here is the exedy listing.....&lt;br /&gt;
http://www.exedy.com.au/SpecSheet.aspx?SpreadsheetRowId=14772&lt;br /&gt;
Even though this is a &#039;light commercial&#039; clutch kit, exedy still make a brass buttom option!!!! hahaha - That would be fun in a loaded up van!!!&lt;br /&gt;
Just like the liteace, this gearbox combo still retains a cable clutch system.&lt;br /&gt;
&lt;br /&gt;
SHIFTER POSITION:&lt;br /&gt;
The W50 that I am using has the same shifter position as a ke70, so fitting one in a ke30-55 will require a bigger shifter hole.&lt;br /&gt;
&lt;br /&gt;
TAILSHAFT:&lt;br /&gt;
The W50 GB is the same overall length as a K40/50, so no tailshaft shortening/lengthening is required. However the output spline is MUCH bigger and a corolla tail shaft needs to have the RA40 yoke transplanted onto it. This can be done with an old Holden (of all things) uni joint!!&lt;br /&gt;

* http://www.rollaclub.com/board/index.php?showtopic=12935 (How To Fit A W50 To A K Series Motor)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;W5X (Toyota Factory 5 Speed manual)&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
This option is probably a bit of an overkill for a K series motor, but by using the bell housing from a G5# 5speed van gearbox, KR42R (7kc/e powered) townace or KM3# etc, allows you to fit a W55, W56 etc celica/supra ALLOY CASE GB.&lt;br /&gt;
To do so you will need to use the townace flywheel, clutch kit, fork and retainer, as well as the slave cylinder as this is a HYDRAULIC ONLY clutch.&lt;br /&gt;
The townace 7k flywheel is still the same overall diametre as a corolla one, but has a bigger again 215mm clutch plate surface, so clutch dimentions are 215x29.8x21T, again here is the Exedy listing...&lt;br /&gt;
http://www.exedy.com.au/SpecSheet.aspx?SpreadsheetRowId=14829&lt;br /&gt;
Suprisingly again there is a brass button option.&lt;br /&gt;
&lt;br /&gt;
Below is a W56 from a KR42R, still attached to a 7KC.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;Recently it has become much easier to source upgraded Bellhousings. Here are some of the common ones with information on how / where to obtain them if at all possible.&lt;br /&gt;
&lt;br /&gt;
In a nutshell, people are finding more power from smaller Toyota engines, this extra power tends to break things, the next thing in line after your engine is your gearbox. Rather than buy six million gearboxes for every time you know you will break one, it may be wise to consider upgrading to a stronger Gearbox.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
In Terms of strength in Toyotas, the more common boxes are (very generally) ordered here from Weak to Strong.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Weak&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
K40, K50 (used on K series engines)&lt;br /&gt;
&lt;br /&gt;
T40, T50 (used on T and A series engines)&lt;br /&gt;
&lt;br /&gt;
W50 (different to W5x - used behind R and M? series engines)&lt;br /&gt;
&lt;br /&gt;
W55, W56, W57 (Used on Celicas and Supras)&lt;br /&gt;
&lt;br /&gt;
W58 (Supra Turbo etc)&lt;br /&gt;
&lt;br /&gt;
R154 (Turbo Supras / Soarers etc)&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Strong&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
I found an article that compares the Toyota gearboxes which was apparently scanned from Street Commodores magazine originally and can be found [[http://www.conceptual.net.au/~peewee/yoda_5spd_boxes.html|here]]&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Things to keep in mind / Disclaimer&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
* Bigger is NOT always better - putting an R154 behind a K series engine is hardly going to be affordable or worthwhile&lt;br /&gt;
* Flywheel &amp;amp; Starter - Remember also that you need to find out what flywheel and starter motor are best suited to use with the upgraded bellhousing.&lt;br /&gt;
* Tailshaft - If you upgrade your gearbox, chances are that you will need a stonger replacement tailshaft or possibly have yours modified / customised&lt;br /&gt;
* Diff / Axles / etc - Remember the weakest link of your drivetrain dictates how much power you can put to the ground. If you keep blowing up gearboxes, chances are that after you upgrade your diff is going to shatter with that big horsepower going through it, it might be time to think about upgrading that as well ;)&lt;br /&gt;
* Brakes - Ok well this isn&#039;t part of your driveline but I couldn&#039;t help but add something here about making your monster-engined-whatever STOP when you hit the brakes. This is something which is too-often overlooked and as far as I am concerned the thing most overlooked in engine conversions. Safety FIRST, not second!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== K to T ==&lt;br /&gt;
&lt;br /&gt;
Now that people are milking out 160 horsepower from the K series engines, it is clear that the K40 / K50 box is becoming the weak link. Fortunately for us, Toyota saved us the hassle and actually made a FACTORY K-to-T bellhousing. This was used in the KT140, KT141, KT142, KT147 series Corona&#039;s and KE74 corolla wagon (as far as I know only JDM or Jap import into New Zealand) which came from the factory with a 5K-U hooked up to a T40 gearbox! Swap it over to a T50 and this is quite a sensible package&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
K-To-T is the perfect upgrade for those who have lost faith in the strength of K series gearboxes. I myself have recently purchased one privately for $205 New Zealand Dollars / $184 Australian Dollars / $138 US Dollars from [http://www.trademe.co.nz Trademe.co.nz] which doesn&#039;t include shipping.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Availability : Second hand there are quite a few on the ground in New Zealand, and using Trademe.co.nz will be your best option at this stage. I have not yet heard of aftermarket (brand new) manufactured K-to-T&#039;s but there would probably be someone out there who would have produced them by now if you searched hard enough.&lt;br /&gt;
&lt;br /&gt;
== K to W ==&lt;br /&gt;
&lt;br /&gt;
This is starting to borderline overkill! A W55 gearbox is nearing 43kg alone, to go completely overkill  you can use a KR## van bell housing which has a G5# gearbox behind it to adapt a K-engine-to-W5x box. As it is the W55 that is known to be able to withstand 300+ horsepower of punishment, a far cry from the best of 165+HP from a K series engine that I have seen proof of.&lt;br /&gt;
The other W box, the steel case W50 can also be adapted using the earlier KM20 van bell housing which has a cable clutch L40 box behind it. (same bolt pattern as the steel case W50).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Availability : A KM36 or KR3# series townace van has the K-W bellhousing, these will bolt up to a W series supra alloy box with only a change from cable to hydraulic clutch.&lt;br /&gt;
&lt;br /&gt;
== A to T ==&lt;br /&gt;
&lt;br /&gt;
Standard equipment behind all RWD 4age engined cars, ie AE86&#039;s, AA63 celica and Carina, AT141 corona.  Theres also the 2nd version with clutch fork on the L/H side that come in aussie 4a-c AE71 or jdm 3a-u AA60 celica. Bellhousing is removable. Not an upgrade as such, but worthwhile mentioning :)&lt;br /&gt;
&lt;br /&gt;
== A to W ==&lt;br /&gt;
&lt;br /&gt;
Never produced by toyota, but there are a few aftermarket manufacturers so probably available second hand all over the place. You have to love aftermarket go-fast-bits and bolt-ons!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Perfect upgrade for anyone looking to put a stonger box behind a particularly rambunctious 4A-GE / 4A-GZE / 4A-GTE / 7AFE / 7AGE / 7AGTE etc etc. With claims of being able to handle upwards of 300 horsepower with ease, the W55 style gearbox is what you want.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Sources:&lt;br /&gt;
&lt;br /&gt;
I am aware of a source in Malaysia that can supply these for approx AUS $~400 landed anywhere in Mainland Australia, but unsure if this offer is still being extended to anyone else. also Dellow (Australia),(research their feedback before purchasing heh), Nite Parts (NZ), Conversion Components (NZ).&lt;br /&gt;
&lt;br /&gt;
== S to T ==&lt;br /&gt;
came fitted to jdm SA60 celica, possibly ST14# corona.  also available aftermarket mostly used in kitcars like the fraser clubman.&lt;br /&gt;
&lt;br /&gt;
== S to W ==&lt;br /&gt;
Factory fitted behind jdm 1S and 2S engines in SA6# celica, ST14# corona with a W55.  these need to be modified to fit a 3S(GE) block because the gearbox input shaft does not reach the spigot bearing.  The diesel C series engine 1C/2C have an identical bellhousing with a W box behind it.  But interestingly most commonly found in vans with a 1C or 2C engine and G series gearbox (G52, G55) which has same bolt pattern as the supra W55 box. Other bellhousings have been known to be adapted like the 2Y/3Y to W bellhousing by slotting some holes.&lt;/div&gt;</summary>

&lt;hr /&gt;
&lt;div&gt;Recently it has become much easier to source upgraded Bellhousings. Here are some of the common ones with information on how / where to obtain them if at all possible.&lt;br /&gt;
&lt;br /&gt;
In a nutshell, people are finding more power from smaller Toyota engines, this extra power tends to break things, the next thing in line after your engine is your gearbox. Rather than buy six million gearboxes for every time you know you will break one, it may be wise to consider upgrading to a stronger Gearbox.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
In Terms of strength in Toyotas, the more common boxes are (very generally) ordered here from Weak to Strong.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Weak&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
K40, K50 (used on K series engines)&lt;br /&gt;
&lt;br /&gt;
T40, T50 (used on T and A series engines)&lt;br /&gt;
&lt;br /&gt;
W50 (different to W5x - used behind R and M? series engines)&lt;br /&gt;
&lt;br /&gt;
W55, W56, W57 (Used on Celicas and Supras)&lt;br /&gt;
&lt;br /&gt;
W58 (Supra Turbo etc)&lt;br /&gt;
&lt;br /&gt;
R154 (Turbo Supras / Soarers etc)&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Strong&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
I found an article that compares the Toyota gearboxes which was apparently scanned from Street Commodores magazine originally and can be found [[http://www.conceptual.net.au/~peewee/yoda_5spd_boxes.html|here]]&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Things to keep in mind / Disclaimer&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
* Bigger is NOT always better - putting an R154 behind a K series engine is hardly going to be affordable or worthwhile&lt;br /&gt;
* Flywheel &amp;amp; Starter - Remember also that you need to find out what flywheel and starter motor are best suited to use with the upgraded bellhousing.&lt;br /&gt;
* Tailshaft - If you upgrade your gearbox, chances are that you will need a stonger replacement tailshaft or possibly have yours modified / customised&lt;br /&gt;
* Diff / Axles / etc - Remember the weakest link of your drivetrain dictates how much power you can put to the ground. If you keep blowing up gearboxes, chances are that after you upgrade your diff is going to shatter with that big horsepower going through it, it might be time to think about upgrading that as well ;)&lt;br /&gt;
* Brakes - Ok well this isn&#039;t part of your driveline but I couldn&#039;t help but add something here about making your monster-engined-whatever STOP when you hit the brakes. This is something which is too-often overlooked and as far as I am concerned the thing most overlooked in engine conversions. Safety FIRST, not second!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== K to T ==&lt;br /&gt;
&lt;br /&gt;
Now that people are milking out 160 horsepower from the K series engines, it is clear that the K40 / K50 box is becoming the weak link. Fortunately for us, Toyota saved us the hassle and actually made a FACTORY K-to-T bellhousing. This was used in the KT140, KT141, KT142, KT147 series Corona&#039;s and KE74 corolla wagon (as far as I know only JDM or Jap import into New Zealand) which came from the factory with a 5K-U hooked up to a T40 gearbox! Swap it over to a T50 and this is quite a sensible package&lt;br /&gt;

Perfect upgrade for anyone looking to put a stonger box behind a particularly rambunctious 4A-GE / 4A-GZE / 4A-GTE / 7AFE / 7AGE / 7AGTE etc etc. With claims of being able to handle upwards of 300 horsepower with ease, the W55 style gearbox is what you want.&lt;br /&gt;

Factory fitted behind jdm 1S and 2S engines in SA6# celica, ST14# corona with a W55.  these need to be modified to fit a 3S(GE) block because the gearbox input shaft does not reach the spigot bearing.  The diesel C series engine 1C/2C have an identical bellhousing with a W box behind it.  But interestingly most commonly found in vans with a 1C or 2C engine and G series gearbox (G52, G55) which has same bolt pattern as the supra W55 box. Other bellhousings have been known to be adapted like the 2Y/3Y to W bellhousing by slotting some holes.&lt;/div&gt;</summary>

&lt;hr /&gt;
&lt;div&gt;Recently it has become much easier to source upgraded Bellhousings. Here are some of the common ones with information on how / where to obtain them if at all possible.&lt;br /&gt;
&lt;br /&gt;
In a nutshell, people are finding more power from smaller Toyota engines, this extra power tends to break things, the next thing in line after your engine is your gearbox. Rather than buy six million gearboxes for every time you know you will break one, it may be wise to consider upgrading to a stronger Gearbox.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
In Terms of strength in Toyotas, the more common boxes are (very generally) ordered here from Weak to Strong.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Weak&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
K40, K50 (used on K series engines)&lt;br /&gt;
&lt;br /&gt;
T40, T50 (used on T and A series engines)&lt;br /&gt;
&lt;br /&gt;
W50 (different to W5x - used behind R and M? series engines)&lt;br /&gt;
&lt;br /&gt;
W55, W56, W57 (Used on Celicas and Supras)&lt;br /&gt;
&lt;br /&gt;
W58 (Supra Turbo etc)&lt;br /&gt;
&lt;br /&gt;
R154 (Turbo Supras / Soarers etc)&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Strong&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
I found an article that compares the Toyota gearboxes which was apparently scanned from Street Commodores magazine originally and can be found [[http://www.conceptual.net.au/~peewee/yoda_5spd_boxes.html|here]]&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Things to keep in mind / Disclaimer&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
* Bigger is NOT always better - putting an R154 behind a K series engine is hardly going to be affordable or worthwhile&lt;br /&gt;
* Flywheel &amp;amp; Starter - Remember also that you need to find out what flywheel and starter motor are best suited to use with the upgraded bellhousing.&lt;br /&gt;
* Tailshaft - If you upgrade your gearbox, chances are that you will need a stonger replacement tailshaft or possibly have yours modified / customised&lt;br /&gt;
* Diff / Axles / etc - Remember the weakest link of your drivetrain dictates how much power you can put to the ground. If you keep blowing up gearboxes, chances are that after you upgrade your diff is going to shatter with that big horsepower going through it, it might be time to think about upgrading that as well ;)&lt;br /&gt;
* Brakes - Ok well this isn&#039;t part of your driveline but I couldn&#039;t help but add something here about making your monster-engined-whatever STOP when you hit the brakes. This is something which is too-often overlooked and as far as I am concerned the thing most overlooked in engine conversions. Safety FIRST, not second!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== K to T ==&lt;br /&gt;
&lt;br /&gt;
Now that people are milking out 160 horsepower from the K series engines, it is clear that the K40 / K50 box is no longer up to the task. Fortunately for us, Toyota saved us the hassle and actually made a FACTORY K-To-T bellhousing. This was used in the KT140, KT141, KT142, KT147 series Coronas (as far as I know only in New Zealand) which came from the factory with a 5K-C hooked up to a T50 gearbox! This is quite a sensible package.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
K-To-T is the perfect Upgrade for those who have lost faith in the strength of K series gearboxes. I myself have recently purchased one privately for $205 New Zealand Dollars / $184 Australian Dollars / $138 US Dollars from [http://www.trademe.co.nz Trademe.co.nz] which doesn&#039;t include shipping.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Availability : Second hand there are quite a few on the ground in New Zealand, and using Trademe.co.nz will be your best option at this stage. I have not yet heard of Aftermarket (brand new) manufactured K-To-T&#039;s but there would probably be someone out there who would have produced them by now if you searched hard enough.&lt;br /&gt;
&lt;br /&gt;
== K to W ==&lt;br /&gt;
&lt;br /&gt;
This is starting to borderline overkill! A W55 gearbox is nearing 43kg alone, to go completely overkill I have heard that some aftermarket manufacturers made a K-engine-to-W5x bellhousing. As it is the W55 is rumoured to be able to withstand about 300 horsepower of punishment, a far cry from the best of 165+HP from a K series engine that I have seen proof of.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Availability :A late KR series townace van has the K-W bellhousing, these will bolt up to a W series box with only a change from cable to hydraulic clutch.&lt;br /&gt;
&lt;br /&gt;
== A to T ==&lt;br /&gt;
&lt;br /&gt;
Standard equipment behind all RWD 4age engined cars, ie AE86&#039;s, AA63 celica and Carina, AT141 corona.  Theres also the 2nd version with clutch fork on the L/H side that come in aussie 4a-c AE71 or jdm 3a-u AA60 celica. Bellhousing is removable. Not an upgrade as such, but worthwhile mentioning :)&lt;br /&gt;
&lt;br /&gt;
== A to W ==&lt;br /&gt;
&lt;br /&gt;
Never produced by toyota, but there are a few aftermarket manufacturers so probably available second hand all over the place. You have to love aftermarket go-fast-bits and bolt-ons!&lt;br /&gt;

* Tailshaft - If you upgrade your gearbox, chances are that you will need a stonger replacement tailshaft or possibly have yours modified / customised&lt;br /&gt;
* Diff / Axles / etc - Remember the weakest link of your drivetrain dictates how much power you can put to the ground. If you keep blowing up gearboxes, chances are that after you upgrade your diff is going to shatter with that big horsepower going through it, it might be time to think about upgrading that as well ;)&lt;br /&gt;
* Brakes - Ok well this isn&#039;t part of your driveline but I couldn&#039;t help but add something here about making your monster-engined-whatever STOP when you hit the brakes. This is something which is too-often overlooked and as far as I am concerned the thing most overlooked in engine conversions. Safety FIRST, not second!&lt;br /&gt;

== K to T ==&lt;br /&gt;
&lt;br /&gt;
Now that people are milking out 160 horsepower from the K series engines, it is clear that the K40 / K50 box is no longer up to the task. Fortunately for us, Toyota saved us the hassle and actually made a FACTORY K-To-T bellhousing. This was used in the KT140, KT141, KT142, KT147 series Coronas (as far as I know only in New Zealand) which came from the factory with a 5K-C hooked up to a T50 gearbox! This is quite a sensible package.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
K-To-T is the perfect Upgrade for those who have lost faith in the strength of K series gearboxes. I myself have recently purchased one privately for $205 New Zealand Dollars / $184 Australian Dollars / $138 US Dollars from [http://www.trademe.co.nz Trademe.co.nz] which doesn&#039;t include shipping.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Availability : Second hand there are quite a few on the ground in New Zealand, and using Trademe.co.nz will be your best option at this stage. I have not yet heard of Aftermarket (brand new) manufactured K-To-T&#039;s but there would probably be someone out there who would have produced them by now if you searched hard enough.&lt;br /&gt;
&lt;br /&gt;
== K to W ==&lt;br /&gt;
&lt;br /&gt;
This is starting to borderline overkill! A W55 gearbox is nearing 43kg alone, to go completely overkill I have heard that some aftermarket manufacturers made a K-engine-to-W5x bellhousing. As it is the W55 is rumoured to be able to withstand about 300 horsepower of punishment, a far cry from the best of 165+HP from a K series engine that I have seen proof of.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Availability :A late KR series townace van has the K-W bellhousing, these will bolt up to a W series box with only a change from cable to hydraulic clutch.&lt;br /&gt;
&lt;br /&gt;
== A to T ==&lt;br /&gt;
&lt;br /&gt;
Standard equipment in rear wheel drive AE86s, AE71s etc. Bellhousing is removable. Not an upgrade as such, but worthwhile mentioning :)&lt;br /&gt;
&lt;br /&gt;
== A to W ==&lt;br /&gt;
&lt;br /&gt;
Very common, probably available second hand all over the place but is available brand new in many places. You have to love aftermarket go-fast-bits and bolt-ons!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Perfect upgrade for anyone looking to put a stonger box behind a particularly rambunctious 4A-GE / 4A-GZE / 4A-GTE / 7AFE / 7AGE / 7AGTE etc etc. With claims of being able to handle upwards of 300 horsepower with ease, the W55 style gearbox is what you want.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Sources:&lt;br /&gt;
&lt;br /&gt;
I am aware of a source in Malaysia that can supply these for approx AUS $~400 landed anywhere in Mainland Australia, but unsure if this offer is still being extended to anyone else.&lt;br /&gt;
&lt;br /&gt;

came fitted to SA60 celica, possibly ST14# corona.  also available aftermarket mostly used in kitcars like the fraser clubman.&lt;br /&gt;
