If I have read all the previous posts right...
(I do have a 5sfe)
To achieve the 5sgte I have to replace the head.( and of course all other turbo apps needed to run)
To get teh 5sfte I replace the exhaust manifold, add turbo, replace oil pan or drill new line, add an intercooler,... and so forth.
My question is who has done the 5sfte with success? Is it worth adding the turbo without replacing the head? Besides the added time of messing with the head installation and troubleshooting it into the right compression again.
I want to Upgrade to a turbo set-up but I can't really decide which way to go.
ha it has been a while since i have last visited this sight but here is my two cents anyways. i have heard that the head is a direct bolt on but the valve angles are different in ways that it will hit the top of the head...also you hvae to consider the strenght of you engine when doing a turbo set up...i have 162k on my 5sfe and i myself wouldny really want to risk puttin on a turbo. but if everything works out for you i would have to say that it would be better to put on the gte head just becuase it was meant for performance purposes as the 5sfe was not.

The motor was replaced by previous owner 40k miles ago.
I've done simple pressure tests and so far so good. If I do got forward I will have a leak down test done first just in case.
Nop The GE head bolt on good, no valve hitting. It's been done.
You'll need the 3S-GTE ECU to work with the 5S-GTE. You get more protential with 5S-GTE due the head design.
5S-FTE is easier, you just need exhaust manifold, turbo and intake. You can add other stuff like IC and boost controller later. You can use 3S-GTE exhaust and turbo, they're bolt-on.

I noticed in several previous posts, there were some conflicts on which gen to get the exhaust manifold off of to make sure it bolted on. I have a 1991 5sfe celica.
Plus, deciding on a manifold with dual port or single port.
Either way I go, does laying money down on a dual port manifold mean more air into turbo than a single port?

Go with 5sfte. You'd have to do some modifications to get a ge/gte head on your 5sfe. If you had a '92+ 5sfe then it'd be a different story.
Anybody ever wonder what the compression is a 5SGTE? I'm thinking it'll be a little low, around 8:1. Sombody worked it out once and if I remember, the 5SGE only yielded 8.5:1 compression. This is all assuming stock pistons of course.
Originally posted by Pineapple I believe it depends on the turbo you pick. Twin port turbo need twin port manifold etc.
I know 4 gen Celica 3S-GE manifold bolt on to my 1990 5S-FE.
Do you mean a 3sgte? Bc I want the turbo app not a NA.
The non-fitting GE head issue depends on which version of the 5S block you use. There are 2 different version, one that works, one that does not. I don't know which is which exactly...
As for doing a 5SGTE... it'll be no different than doing a complete 3SGTE swap. You MUST swap over all sensors and such on head, such as MAP or AFM, TPS, dizzy, etc. That will require a complete harness change/modification and you'll either need to run off of a 3SGTE ecu or go with a standalone. It's not a "bolt-on" sort of deal for those that like that stuff... It's not a matter of the turbo either. You can run the stock 3SGTE equipment (ct26 dual/single, ct20b) or you can go with an aftermarket set-up. If you don't know what that means... this swap is already beyond you. The other problem is the strength of the 5S block, which is not anywhere as strong as the 3SGTE block. You should do things like upgraded low-comp pistons, forged rods, bearings, etc. Easier said than done... but the one 5SGTE I know of did post some very impressive torque numbers over a similarly equipped 3SGTE.

Which one?? 5sfte or 5sgte
