5sfe head swap? Options

[momentai99]

Hey guys, I have a 5sfe in my celica. it's a 94 gt and I was looking for a little more, how should I say oomph out of the engine.It's decent but not good enough yet. My other car is a 350 horsepower camaro so understand my need for speed.
I've been told I can either do a head swap although with a pre 97 model that wont work? thats what I heard.
I'm not interested in a v6 swap. The only other thing I can think of is a 3sge or 3sgte swap?
I have a 5 speed tranny and I can get the stuff for less than a grand (have a buddy who runs a shop).
So its a matter of choosing and deciding the easiest option. But that 3sgte with the twin entry turbo sure sounds nice....


Also in the 5sfe can I port and polish the heads for less restriction? I've been told thats where the main problem is with the engine.

have you guys even looked in the FI stickys?
I made 300+whp on stock internals years ago, and ran it @ between 240-270whp for 5 years before i popped ringlands twice because of my lack of tuning skills, and fighting the stock ecu.
get the stock ecu out of the equation like you guys are talking about, even a mild set of cams, and a decent turbo and 280-325whp is no problem, provided you can tune it properly.
why link someone off site, to info that "kinda" translates to the 6gc (99% of that stuff on the 5sfte site is all ment for mr2 guys, running older engines than we do..and while it applies somewhat, there is better info right here in the stickys)
my turbo thread is very detailed, with lots of pics, and great info that shows all the ups and downs of doing a 5sfte setup. over the course of over 5 years, i made over 50 dyno pulls with several variations of my setup, and also built and tuned a couple more as well.
hell, even with the crappy ebay turbos i made 285whp @ like 16psi or somthing tuning shannons old 5sfte (again, the info is in the stickys, both the dyno sticky and the FI stickys) and that was tuning with just an SAFC neo..lol
