I'm wondering if anyone has had any successful 5sfe turbo stories they'd share?

I'd imagine the stock ecu would cope with 5-6 psi

its popular in the states and they get some big numbers. please go for it, would be awesome!! the only disadvatage those blocks have is that they dont have the oil squirters on the pistons like the 3sgte has. but ive heard that the 5s block is stronger.

DO IT!!

the 5s block is stronger but the pistons and rods are weaker, and i think he's asking about wackin a turbo on the stock unopened motor.

the big power 5s motor's are generally 5s block's and cranks with forged rods/pistons and a 3s head fitted, but i'm pretty sure that's not what he's talking about.

there's been a couple forum members that've done it, stock ct26 with the stock 3s manifold and some fiddling with the wastgate to lower boost to 6psi.

Read over www.6gc.net LOTS of members turbo there 5SFE, generally cope with about 250hp without changing internals.

You got it right guys, was thinking of keeping things all locked up engine wise and running the stock motor.

I know they are still strong and i'd be only hoping for 6psi at most. I've had a couple of turbo cars before now, 1 was a gt2 st162 with a gen 1 3sgte.

I love the bottom end torque of a 2.2 but want the best of both worlds smile.gif

I'd love to make a killer 2.2 setup with some hot bits smile.gif

The other option at the moment is investing in some reground cams (getting mine redone)

The 5sfe has potential, i know it does lol

At what price? Gosh knows but they are just ideas passing around my head atm.

could always stroke out a gte with a 5s crank for the 2.2 smile.gif

before you bother with cams and stuff id go out and get an aftermarket ecu otherise any gains will be fair minimal

Could always be done with piggy back systems such as a safc and sitc ignition computer hehe

stroked 3sgte would be the best option for power but your not really after too much. i also loved the 2.2 at low revs, much better than the stock 3sgte..

gt2 with a gen 2 motor would be ideal.. too bad you cant make it a rwd though.

I've testing the stock ST185 CT26 AUDM turbo with no MBC or EBC and no stupid Turbo VSV... It runs between 5 to 7psi depending on what gear you are on when you go WOT.

So unless someone's fiddled with my CT26's wastegate, it should not require any modifications to make it run 5-7psi with it plumbed from the turbo directly to wastegate and the second wastegate input plugged.

And to answer the initial question, I met a guy who put a CT26 (I think) onto the 5SFE... Looks less clustered than the 3S-GTE and I believe he ran 9 or 10psi on stock internals and stock ECU.... But I might be wrong...

Your stock ECU wont handle any sort of boost sorry. Plus simple fuel adjusters like SAFC don't work well on MAP based cars so you would be disapointed in the results. Thats not to say that its impossible. Just that with the price of 3SGTE engines being so low it would cost more to turbo a 5SFE.

Depending on how ghetto you want to go, you could put a volt clamp on the stock MAP sensor to stop the ECU knowing that you are running more air through, and then map extra fuel at different rpm load points but that is a really dodgy way of doing it and you end up with a few flat spots where the fuelling doesnt match your actual engine load.

I have a old Hot 4's magazine where I guy in Perth with a Gen 6 Celica turbo'd the 5sfe. I'll try and copy it and post the jpegs of the pages here on the forum.

Also have another Hot4's mag where another guy stripped the motor down, put hi-comp pistons in (10.5 to 1) and then a regrind crow cam and other port and valve mods as well.

Oh awesome, if you could scan the pages up that'd be great!

OK I have finally scanned the pages, but to maintain image quality the scans are reasonably large, between 1.5 to a little over 2meg each. Whats the best way to get them uploaded here. Can someone host them? I see that there is a 500k limit for uploads.

Theres a 6th gen on either here or toyota owners club, but its in perth. The guy who owns it didnt do the conversion himself, but i recall him saying its the stock engine in there but turbo. So im guessing its the 5sfe

I was thinking the same thing.

If/when the motor goes off in my ST184, to just get it reconditioned/modified for better flow and higher comp pistons etc.

Don't feel like going the whole turbo thing and the hassles with getting an engineers report and blue plate etc etc

But then - I also plan to give the celica to my son in a few years when he gets his licence. Then buy something else for myself.

But my WRC Trophy Celica was a great buy when I got it. Had a few things that needed fixing, like engine mount and A/C gas conversion. I then put DBA rotors and Bendix ceramic pads in with kyb shocks and lowered king springs. But it was literally driven by a little old lady for most of its life and she was the second owner from 40K onwards - it's had a complete gearbox replacement and I put a new exedy clutch in it and everything else is still all good. Motor is still very strong.

The motor won't go off in your 184 if you look after it, they are pretty resilent beasts. But trying to get any power out of it is like trying to get blood from a stone. Just enjoy it the way it is I say smile.gif

in my experience, turbo 5SF's are horrible. the comp ratio is too high for a good turbo install so it detonates as soon as you wind up boost more than a few PSI. the pistons will handle a few PSI boost Ok (not much more for long), the factory computer wont properly cope with ANY boosted install at all. the bootom end is tough enough for street applications, but of course the block does not have the piston oil squirters found in turbo 3SGTE's etc, so their crown temperatures are probably excessive.
