1979 T18 With 3tgte Turbo

[cheviot rola]

Hi everyone. I'm new and fairly amateur to the forced induction scene, as i grew up around NA V8s, but am a diesel/ petrol apprentice mechanic, so i have the basics.

ive recently picked up a t18 with a 3tgte in good roadworthy nick, and I'm finding it extremely hard to find parts of any sort for both the engine and the car. i wanted to know what a good turbo upgrade would be whether it be bigger toyota or a garrett of some sort. also wanted to know if the motor utilises a t3 flange as standard.

are there any sites available worldwide that supply any aftermarket performance parts or do i have to go custom all the way.

At the moment the car is running 10psi on 1st stage boost and 19psi on 2nd stage, but lately it has been spooling alot later than normal (approx 3400rpm as opposed to 2900)and 2nd stage boost drops to around 14-15psi at 6-7000rpm(is that normal), what could be the cause of that. can the supra w57 or w58 box mate to the T50 bellhousing?

what is a good LSD that can fit with as little number of hassles as possible ( and possibly disc rear as well).

it has 147 rwkw and everyone that knows everything about nothing thinks I'm going to blow the engine, but the last owner has had it set up like this for the last 7 years ( thankyou peter howard) and he only had 1 problem with it.

is 19psi a little excessive? there is someone who has this engine in a ta22 that was tuned at the same shop mine was that pushes 38psi ( can't get in touch with them) and someone in melbourne with 500bhp from this engine. i am trying to attain relible 350bhp/ 250rwkw therabouts.

any info would be greatly appreciated.

Its dropping down to 14psi by redline simply because it simply can't flow that much. Above 14psi out of those turbos just results in pumping in a lot more hot air. For that reason 19psi is excessive.

 

Sweet bugger all as far as aftermarket goes, the engines were Jap/Euro only, so I hope you're happy with fabrication. The turbo isn't a T3 flange, its a toyota flange which shares itself with..nothing. However, if you'd be looking at a custom exhaust manifold anyway with the power you are after.

 

The big hp TA22 I think you're talking about would have been SIKTOY, can't remember the owners name. It made the power a few times, running a very extensively worked head, complete internals, big to4 with a 60-1 front cover. He also went through quite a few motors. I can't say I agreed with a lot of his setup, but whatever it worked, albeilt for a short time.

 

The main issues with the motor, is the factory ecu, the factory turbo, and well thats about it. Internals..I dare say be at the point where you'd want to replace the pistons at 350hp.

ive also heard rumours that skyline r31 rear acles will fit nicly in the diff housing of the t18 to give you 4 X disc brakes

[cheviot rola]

thanks for your help, seems these motors are good as stockos and nothing more. had a look at BRD and couldnt find much. are the 2T series and the 3TC similar in any way besides capacity, eg valvetrain, cams, timing gear etc. also, i don't suppose a 4A series or 3SGTE aftermarket turbo exhaust manifold would fit to the 3TGTE would it? wishful thinking.......

yeh Valandor those rumours are true, and I'm not sure about those manifolds i wouldnt think they would, yeh cams and

 

are the 2T series and the 3TC similar in any way besides capacity, eg valvetrain, cams, timing gear etc.

yes the cams and timing gear intake exhaust ans so on are the same, only 2t rocker asembaly's are different 2 3t's, ill find the information about them and post the site with it on it

Hey mate check this out.

l.s.d

[ke30king]

the rumor sean was talking about is not true. me and sean tryed it the other day. the axels ar too long and the diameterbut we will work out how to fit the brakes to the diff housing and post a how to on it.

 

cheers, lloyd

to fit a CT26 from a 3SGTE/7MGTE all u need to do is file out one of the holes and it'll fit the 3TGT turbo manifold. 19psi is probly a bit much, are u still running the T50 gearbox? i hope its intercooled. u need a G series bellhousing to fit a W series box this will still retain the clutch slave cylinder on the correct side. where abouts are u located?

i'm in albury at the moment but i go back up to sydney every now and then. i don't know what gearbox it is, its the T18's original box.contacted DELLOW and they couldnt help me, despite someone on this site selling W55 and b/housing for 3TGTE. old owner said it bolted straight up to the motor as theyre both 3TC and 3TGTE are same rear end. that was seven years ago and havent had a problem besides the detent lock on third ( have to to go back to second to go to third, if in fourth/fifth). ive got a replacement ct20 for the meantime while waiting for a mate at SNORT performance to do my fabricating. its intercooled, but its small, like around 250x180x50. also, a point on my dizzy was arcing out onto the airflow meter, through the spark lead's boot. it was jumping a good 25-30mm. is this common? ive never seen anything that extreme....

yeah ive seen subarus that do this they arc on intake manifold bolts. u need a new lead maybe dizzy cap but lead is the cheapest option so try that first. the G series bellhousing may not retain clutch slave on the drivers side ive found, u will need one that came out of a car with a 3TGTE and a w55, like corona GT-t and carina. yeah the T50 will bolt to all 3T

[melvin79]

hi,guys I'm also putting together a 1979 with a 3sgte and i used a 3tc bell housing from a 1980 and it worked for me for the conversion with a 3tc starter

[white_sandshoe]

hey there cheviot rola,

 

I've just picked up a 1979 TE72 with 3T in it. I've been digging through forums and sites looking for as much info on building these engines as possible... hope some of this helps.

and turbo upgrade here...

seems adapter plate is a good way to go.

Other than that, they seem to be fairly painful engines to find parts and info for, but it is out there...

There is also some info floating about regarding putting a 3SGTE in place of the 3T, which might get you the figures you're after with more reliability and end up being easier on the wallet.

I'll be watching closely here, and will fill you in on anything else i dig up. Good luck!

[tas_ae71]

there are a number of box's that will bolt up,

 

one of those a is the 6speed from the altezza/is200?

 

if the motor has had a fair amount of boost going threw it for 7years or more than you may want to think about pulling it down and replacing a few of the parts, like rings bearings.

 

for all your tought building needs, these guys specialise in toyota 4cly 2/3t, 4age etc. lots and lots of parts for 3tgte.

heya.

the internals from a 3tc can be used in a 3tgte. the block's are basically the same except 3tgt has a turbo oil return hole and knock sensor in the block. so buy forgies and rods for a 3tc and use them. the american 3tc have full counterweight cranks like the 3tgte do. the bottom chain and tensioner are same.. but top dohc tensioner, chain and chain guides need to be bought from toyota or donated from a 2tg(eu) or 3tgte. 18rgeu also shares alot of the dohc timing gear. the chain guides are the most expensive.. and take it easy with the tensioner hanging out of the head under the dizzy.. if that gets a fair knock it'll snap off.

head and exhaust gaskets are same size as 2tg. intake is much different.

bellhousings for W55 come on any 3tgte (ta63 celica GT-T, carina GT-T and tt142 corona GT-T). and also 3teu (pushrod) ta63 celica and carina.

The G series is referring to 6cyl 2ltr 1GEU, 1GGE, 1ggte, 1ggze engines.. the only difference being clutch is on exhaust side of a 3t and is missing one bolt on intake side of engine.

i've yet to see a toyota van G series gearbox behind a 13T engine (I'm looking)... they always have the L20 steel case box which will fit a steel case W50 5speed. (so could be a cheaper option than genuine 3tgte bell with w58). can also get 3t-w50 bellhousings from pre 1981 coronas and celicas like the tt132 and ta45. the alloy w55/w58 etc are stronger and easier to find if you can afford it.

ok too much writing already.

as to power.. if i were aiming for 350rwhp... ditch everything except the bare engine.. so we're talking aftermarket ecu, bigger injectors, bigger turbo, front mount, upgraded fuel system, bigger exhaust, w58 gearbox, HD clutch, forgies, new bearings, bigger throttle body.. um yeah something like that. and dyno tuning! i read on toyota3tc.com that the 3tgte rods bend at 400hp so prob good idea to install stronger rods whilst engine apart.

i wrote the 3tgte info page on toycrazy.net so feel free to email me any info i can add to it :S

cat just farted on my lap so i gotta go
