A slightly different approach to the turbo Options

[BigEdge169]

I talked to a local mechanic not too long ago about the infamous 3S-GTE swap and he suggested something a little different. He said that instead of using a 3S-GTE, use a 3S-GE and beef up the bottom end and boost that. This engine is bigger (2.2 compared to 2.0) and puts out better torque, especially in the low-end range. He said that they haven't done this in any Celicas, but they have in several MR2 turbos and it worked better than building up a 3S-GTE.
Let me know if anybody has tried this or what you think about it.

You mean 5S-FE, cuz 3S-GE has 2l...

[Jabberwock]

I'm probably going to do the 5SFE setup and found that burrien and another company has a turbo kit in the makings.

ok how about this for us ST(7afe) owners... seeing that our engine have real nice tourqe at around 2700 RPMs why not turbo the engine to 6 psi on stock internals and tune the transmission if done right ..WOW well thats what my pops told me he did back in the day to his VW bug..

[BigEdge169]

No, he did say 3S not 5, that's why I was asking if any else had heard of that.

Also, since I do have the ST, I had thought about just turboing it, but my car has about 160,000 miles and even though Toyota makes some reliable engines that run for a long time, I don't think that would be too smart putting that much pressure one the bottom end of the engine.
Has anyone gotten custom pistons and rods for the 7A and if so how's it working out for you?

You can use a 5sfe short block with forged pistons, rods and such with a 3agte short block. You will have to swap the wire harness just like you would a 3s swap. All this will give you a 5sgte. That is pretty much a strocked 2.2l 3sgte. Real stroker kits for the 3s use 5sfe parts (Crank).

Your guy is dead wrong about the 3sge its a 2.0l and has cast internals. So theres no point in that. Maybe he said 3sfe???

Thus the age old question: Do I want a really powerful economy block engine that cannot hold big power, or a performance built engine that can hold 400 with no problems? The price is about the same bro, you decide.

(and 4agze internals should work on a 7a if you want to build it.)

That's all I wanted to know, and it lets me know something about the shop....they probably don't know **** about Toyotas, just Hondas

Does anyone know of any good shops in the Houston area?

go the 3sgte route.. fallenhero made a very good point.

By the time you got done with the project you would spend the same ifnot more and would maybe hit 10ish psi if your lucky

3sgte does 12-14 stock and can make more with a little ecu tuning.

BTW 6psi is kind like you farting... you might hear it, probably will feel it, but usally isnt worth the effort to squeeze every little bit of it out. just pray you never smell your turbo (cookin)

just to clairify things... when you start messing around with high compression ratios and even moderate levels of boost you start breaking things, important things which usally are expensive... funny how that works... newayz that is way turboing a car that wasnt ment to be turboed isnt the best idea, unless you do a complete engine rebuild, and ask anyone who has done it its a little more than just buying a set of 400-500$ pistions.. thats the easy part..

[NEVERSTOP]

yea I understand the point your making there.. and it is a good point until you notice the long term effects of running high boost with high compression, It like inflating your car tires to max psi at 20- freezing and then driving to texas.. eventually something is gonna give....

yea 6psi at 10:1 is gonna make a diff but for how long is it safe for? and for a 40% gain might as well look into a supercharger setup for it - custom setup isnt too hard to do and alot safer on high compression motors.

[FallenHero]

Just buy a 4age black top for 3 grand and be happy with your six speed.

I'm changing my ways right now. The 3SGTE is the way to go. I have always said turboing a 5SFE is OK, but recently learned that yeah it';s ok...but the 3SGTE is much better.

And BTW...the F and G are difference in the heads. The 3S and 5S essentially have the same block. The difference in size and performance is the next letter...either F or G. F is generally an economy head while the G means more performance. That's just kind of a rouch outline of how the engine codes work for Toyota. There is a stroker kit for the 3SGTE as well as for the 5SFE. I will post links if I can find them again.

[Guest_Matthew_*]

if you get JUN's stroker kit (like i have) you have to bore out the 3s-gte to 2.2 liters.

it MIGHT work because the block is about the same


and 97sccelica, i had a turbo on my 5s-fe and it was at 8 psi or so for normal driving and it does make some difference but its just putting more pressure on the engine than its supposed to have. after a while like neverstop said something will go.

the 3s-gte can handle (3rd gen) 17 psi on STOCK internals. thats enough to give 325hp easily. that will increase with air/fuel tuning.

without a major rebuild on the 7a-fe or 5s-fe you will never see those numbers and keep the engine very long.

but i do agree with you. if someone doesnt have the money for a swap then turbo your stock motor.

[97sccelica]

i understand, but 6psi isnt that high and so long as you do things right the engine shouldnt feel too much strain.

but yes, the 3sgte will always be better, but many people(california people) dont have the option as easy as some other people.

what my point is, is dont discourage certain people from ideas. i am fully aware that a turbo setup(with all new parts) is just about as much as a 3sgte swap, but i couldnt go ahead with a swap that could possibly get me into smog problems.

the 7afte is a temporary solution. i have other plans, and i personally, dont want more than 10psi(once i get the FMIC and fuel pump) because, i think that is too much for a FWD car. make my car have the power it looks like it has and move on. i would love to get a GT4 any way i can, if not, then maybe a 240z turbo project, no smog, no fancy crap, simple engine.
