Hi,

I assume when you say it is a twin-cam 2T engine, you mean it is a 2T-G engine. Which looks like this.....





Or, is it really a 2T engine (ie not a 2T-G), which looks like this....


The 2T-G is the better option for turboing, and will probably be easier to do and will generate more power. You could also try and get a 3T-GTE which is a turbo'd 1.8 litre 4cyl in-line, T-series engine that can be fitted.

yes thats the one it has twin solex carbs

too easy, find yourself a 2tg efi manifold, a 3tgte turbo manifold and turbo, buy an aftermarket computer, wire up and away you go.

OR swap in a 3TGTE. Larger capacity, factory turbo, blah blah.

Plonk her in, sort out your plumbing, wire it up and win.

what parts would i need and how much would i be looking at

in future i plan to take the car back off the road and put something with alot more donk i dont have my licence

Hi,

It depends if you wish to turbo your existing engine or put in a 3T-GTE engine. There are many ways to do it, and the cost will be a few grand minimum.... and from there it only goes up!

And, you will need to upgrade your brakes, gearbox and diff. The gearbox and diff may hold up for a while, but a few hard launches and spirited drving will see them off to early retirement. Brake upgrad eis uber important. And, the suspension is still probably origina, which means the shocks are pretty worn and the springs maybe sagged... so you should get them done to.

The problem is, you need to factor in the cost of making sure the drive train, steering and suspension are done to take advantage of the extra power and the way the car will be driven with this extra power.

I heartily agree with this statement.

It's probably even worthwhile doing all your suspension stuff first if you're going to upgrade it.

A complete re-bush, some lowered + stiffer springs and stiffer short stroke shocks, adjustable panhard rod, fatter swaybars is a good idea. Do your steering components while you're at it - new tie rod ends (inner and outer), new pitman and idler arms and a re-condition steering box will tighten the whole show up.

Some nice 14 x 7 wheels with good tyres and she'll feel like a completely different car!

alternatively you could do a hot rebuild of the existing motor with the 3t crank, a slight overbore, and big cams.

you'll get adequate performance, while keeping the car more original, and getting less hassle from the po-lice, and save a few hundred dollars and many hours.

i've been toying with the idea of modifying a 4age turbo manifold to suit the 2t flange.. I think very similar port spacings. the price for the stainless manifolds is pretty good at $180 odd i think, cheap t28 etc, custom computer, cooler, piping, efi fuel system and efi manifold or you could run a cordia turbo throttle body or similar on a stock 2t manifold (cheaper)

Depending on the casting number of your head, or what has been changed etc you may be limited to boost as low as 6psi to be safe. I think the lowest 2t-g was 8.4 or 8.6:1 but can be in the 10's as well. If your after big number pulling the engine out to rebuild comes into it and sometimes that tips things in favor of just dropping in a 3t-gte, but even then the 3t-gte will need to be rebuilt to suit decent power.

thanks guys thats some handy info there my plans once its painted and complete to drop the 2t back in it but i just want a bit more donk once im off my p plates and know i wont crash and kill myself and the car il drop sr20 with a big snail

As easy as that ?? Now you've got me thinking.

My long term plan was to turbo a 4AGE unit, but if all I need is a 3tgte manifold then I may as well turbo what I have already. I'm only after 200bhp-ish.

I am in the UK, so we never got the 3tgte. If I managed to source the turbo manifold, what turbo could I use with it ?
(I ask because it would save me a bundle of cash in shipping if I could source the turbo here).

I've got a 3tgte turbo manifold that I can't give away which you can have if you are willing to pay for the postage to the UK.

This will only fit the toyota ct20 turbo which is pretty old now and hard to get and is not to be confused with the so called ct20b that is off the gen 3 3sgte motors. You could make an adapter plate to suit a different turbo though.

The 3TGTEU manifold might be pricey to ship as it was a heavy cast manifold. They came with CT20 turbos. The 3TGTEU (1.8L) produced about 160hp at the FW from memory but that was without an intercooler and running low compression somewhere around 8:1. There should be plenty of info on the 3TGTEU engine on these forums if you have a search. Whole engines as well as parts come up in the classifieds ever now an then also.

I'd like to take you up on that. I'll PM you details, but I may have the option of you posting to a contact I have in-land. He could them bring it with him when he next comes to England.

I think it would be easy to find a suitably sized turbo here and make an adapter.
