Hello I have a question. You know how it is possible to bore out the cylinder displacement - Eg. 1300cc to a 1400cc - well, is possible to bore out the size of the valves? - (and replace with larger valves) Just an idea... (oh and the spelling fairy checker says theres no mistakes :D)

Hey all Just a question about valve springs in K motors, (could be in other motors as well) I have seen some valve springs which look like '2' springs intertwined into one, is this just a cheap way to make valve springs extra strong ? or is there some sort of other explanation for this? Thank you in advance :P Ted

Hi, Just out sourcing more info on K motor cyclinder head valve seals. Now we all know the 4K and better valve seals seal a whole world better than K motor seals. So What I am just after is a picture of some 3K old style seals then some newer 4K seals? Or just info on how to install newer style seals into an older head? Cheers Cameron

Hi, After slowly working out how to get my solid lifter to 5K conversion sorted I decided to set my valve tappet clearence to what the K-B motor had which is 0.010mm intake and 0.023mm exhaust. But tonight I flicked through my 4K manual for a KE70 and it runs 0.020mm intake and 0.030 exhaust clearence. So what would be the better one to go with? the tighter K-B ones or the larger 4K ones? Also what is the possible problems I can expect with a gap that is to small or to large? Cheers Cameron

hey all just need to know what the valve timing is for a 3tc i have been looking for it all day and no luck so if any1 knows let me know thanks

i thought i'd start this because there are some differences in 5k & 4k blocks. the 5k has 2, the weak one has a welsh plug under the water pump and welsh plugs down the camshaft side of the block. only ever seen one. 4k's, there were 500 made that had no strenghtening around the welsh plugs on the maniflod side. i've struck 2 of these blocks in 15 years and both cracked through the plugs, one was in our rally car in NZ and the other was when i worked for an engine reconditioner here in brisbane, i told them about the problem, but they went ahead and reco'ed the engine, 2 weeks later back it came, you guessed it, cracked though the welsh plugs. anyone e…

Does anyone have a link to a site that shows what the coding means on the data plate (example: axle, transmission, paint etc..)?

Hi, A few small bits need assembling on my KE15 sprinter and I am jsut looking for advice. The rear drivers side vent on my sprinter was removed when car was repainted and now needs reinstalling. The back of the vent pictured below has 3 pins in the corners (see photo below): Now the holes in the car look like this: So I am wondering HOW do I stick this in. As in factory how did they do it as the top holes are a lot bigger than the pins but the bottom hole has like a rubber goo in it that makes the fit tight so just curious how people have put these in? Also the pins on the back of the grill are similar to the ones on the back of badges so it might…

Hi i have just acquired a AE112r seca for $1200. Pretty rough but not too bad for what i paid. I have only had it a few days and have noticed that there is a vibration when at a cruising speed in any gear... There is also what i would describe as a pop noise when accelerating from from a constant cruising speed... example of the vibration would be if cruising along in say third gear with no real load on the engine and then putting your foot down steadily. It can be felt through the whole car... Doesnt feel like a wheel balance/alignment issue... I was thinking maybe engine mounts??? Also the previous owner smoked like a chimney and now the car smells as you woul…

where do you get it? how much does it cost? is it a good finish? does it crack? thinking my new paint isnt going to match the black interior i have in my 20 and i wanna do other things before i start forking out for interiors? any other helpful products to use instead maybe?

So my drums are screwed and I figured I'd do the conversion while I'm in there fixing the old. So my question is has anyone done this and is anyone keen to give me a hand to do it. It's my daily so I'd be keen to do it asap. Also if anyone is near a wreckers who has seen the required parts and is keen to grab them and post them that would be great.

I have installed a VN V8 master cylinder into my KE30. I forgot to ask which outlets are for front and rear. Its too late to call now, so is there anyone that can answer this for me, and possibly post a pic. I have to get these brake lines bent into shape and then sent off to have the correct threaded ends on them....preferably tonight or tommorow as the christmas holidays is quickly approaching.

Folks, I have a set of pistons that have been touched with with the die grinder in order to decompress a little. In order to work out my CR, I need to know the volume of the stock piston dish Does anyone have one handy they could measure, or even if you just know what it is! While i'm asking, what is the stock comp on a 5k. cheers tp (this is where the old "mate, theres 17 different piston types for 5ks" comes up....)

hi just wondering is there any difference between Volvo 244/245 and 240 calipers, the numbers are models, some one would be sure to know as I'm doing research for a brake upgrade cheers casey

Hey guys, Okay before you just shut this down and giggle to yourself, My girlfriend has a Vt acclaim and I'm really keen on fitting the electric seat's to the rolla. I know how bizarre it seem's but I was wondering if anyone know's the rule's and regulation's for these. I have heard that as long as the original rail's fit with no adjustment's then an engineer's certificate isn't needed. Could anyone confirm this please? With this in mind, I would also at the same time like to re-upholster the material on these seat's to suit the interior of my car. I need a very talented upholsterer for this and any help would be muchly apprecia…

Hey guys! I know not many of you would have experience with W40 and W50 gearboxes, but hoping someone can tell me if a W40 shifter will fit into a W50 box? Any help would be great :) Cheers

i've just gotten a w55 and i was wondering what will i need to put mate it up with a 4age basicly i search and came up with nothing i soon will have a 4age and yeah will the w55 mate up with the 4age with the A to W bellhousing or is there any special peace or bearing or clutch i need cheers andrew

now someone probably already knew this, but i had to check it for myself. the box i tried it on was a 22re out of hilux/corona st141-2, bolts stright up, so the bell housing you want for this conversion is from a late townace with a 7KC or E. thanks to mr beerhead for making me get my ass into gear.

i just want to know..will w55 gearbox from 1g series engine fit in.. 1.20v 4age 2.4age tvis 3.4agze is it direct fit or we have to use back the t50 bellhousing? how about the longshaft?

Hey all, After compatible and readily avaliable crossmembers that will allow me to bolt up my w series gearbos to my ke35. All help appreciated. P.S. don't say custom :) :)

I'm chasing a right hand rear quarter glass window seal for my ke70 wagon. i have the glass still but the seal is rather broken. :/ i have looked on ebay but other then that I'm not really sure where else to look for something like that? if anyone's got any ideas id love to hear them or even if they have one they are keen to get rid of. thank youu.

Hi all i was after a fuel cap to fit a ke36 i was wondering if any one had a spare they would part with for $$ or would no were i could get one (preferably original) i have alredy bought a couple from diffrent places but they have been crappy generic cpc brand ones that continue to leak fuel down the side of my panel leaving ugly stains (also how would i go about removing the fuel stains in the paint)-the ajax isnt cutting it any help appreciated thanks guys

Hey guys, i know this is the wrong section, but i have had no luck in the wanted to buy section and been looking everywhere but no luck!! thought it might get a bit more exposure here. looking for mostly the rear bumper for a KE30, good straight condition, does not need to include lights. and Front one could also be nice in good straight condition. I'm from Eastern suburbs of melbourne am prepared to travel a bit Thanks guys

I'm in need of a front brake upgrade and a diff upgrade. either to buy or advice on what i can do. currently have a 1.8 turbo engine and need brakes and diff that will also keep engineer happy.

I'd like to get my hands on a manual that has a how to all of the interior parts of an AE82 (toyota corolla hatchback), like in dash (aircon, heater core etc), in door parts etc. any help would be greatly appreciated. Downloadable if prefferable plz

Hey everyone, I haven't posted here before and am finally about to join the rollaclub! I am planing on buying a 1981 KE55 this week, its in pretty good shape for the price but I am planning to do a lot to it. Anyway, what would a good diff be for a 4AGE motor conversion as this is what I'm planing on changing to in the future. I'm asking this early because my parents are freaking out about safety and having some disk brakes would ease there minds a little bit, the current motor is still the stock 4k. I would also want to put a LSD in. thanks heaps, Kyle

I swear I have done this kind of thing before even though it doesn't seem like it. This car is kicking my a$$ everytime I get to the next level with it. The exhaust is done and all seems well with the quality. I go to start the car and I have no spark. It's got to be in the distributor/points/rotor/timing area I think. Here's what I have done: I have checked to see if there is a fuse that could be blown and cannot find one. There is 12v at the coil with the key on and 12v at the ignition lead going into the top of the distributor. I have checked and the timing appears to be right. I cannot find any wires that are cooked/loose. Again, this is a 3k…

I'm puting a hilux rear and its 5 st and i need some think 4 the front lil help

Hi, Don't know how well this would work but mm worth a shot if you have a spare K motor or 4age as they have an air box so might be good to place water container there. But below is the link: http://www.zerotohundred.com/newforums/sho...ad.php?t=130747 Cameron

after blowing the seals out of turbo(rear oil seals) I'm worried its a water cooling problem or oil problem....... it might have been a bad turbo from day 1 but want some advice so i can not worry so much about doing it again ok so my setup is 1.t piece bottom radiator hose/and the water line goes to turbo 2.top water neck off the head that goes to top radiator hose has a outlet on back of it that usualy goes to the rear of head/this now goes to turbo is this correct???????????????????

Hi all, I have a 95 toyota corolla seca (7A-FE engine) which needs the water pump replaced. Is this a job suitable for DIY. I want to give it ago mysel but I've heard horrible reports about lifting the engine to gain access. What would a mechanic roughly charge to do the job.

So my waterpump has decided to take a shit. It seems like its leaking internally and coming out the little drainhole in the bottom so its rather rooted. Is there anything i should know before i go tearing shit apart?? Luckily I kept the whole pump and fan assembly from my old engine so i should be able to just whack it on.

on my 4agte in the last two months ive gone through 3 water pumps clutch fans and two radiators. they keep popping of the front were the pulley bolts on. I'm thinking of going electric, any suggestions?

OK so my car idles below 1grand (usually idles at 1grand) and putts along for like 10 seconds then a burst of normal idleing happens for a split second, then it idles bad again. Idles even worse after accelerating, stopped dead a few times and I ended up having to run with the choke out slightly. Putting along at walking speed when I parked it was doing small bursts of power too. Any suggestions? :n:

Well guys, since the 7k has died we've decided to do a full rebuild It is coming out of the car this week. My engine rebuilder has never done a 7k and said he has very little tech data on them. If anybody has any info that may help it would be appreciated. We hope to develop it beyond factory specs. So things like cam angles , valve settings, basically anything and every thing. When we have aquired as much info as pos we will then work out what to do. I will try to keep as much info as possible and post our results when finished

Hey guys i was just wondering what webber i need for a 4ac? cost? etc... Thanks

hey guys i am looking to upgrade the carby on my 5k i was really wanting to go sidedrafts but i simply can't afford it at the present time. i have been looking into the webber side of things for it. the motor is fully ballenced with standard bottom end hydrolic lifters and all. it is running a lumpy as hell cam (unsure of specs as there are no new markings on there to identify what cam profile or who did it) a proted, polished and shaved 4k head, coby headers into a 2" freeflow exhaust.(and is fully rebuilt under 5,000kms ago) the webber i have come accross is a webber an old guy here in my home town (in NZ) there is a stamping on the side of it saying "34 DCHD" a…
