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.

^^^ you are correct in alot of the information that you posted above. however a 5S-FE turbo will never compare to a 3S. just like you said it all has to do with the angle of the valves. but it also has to do with the camshafts too. the 5S cams are just flat out not designed to make power. a 3S with stock cams will always outflow and with aftermarket cams the sky is the limit. so just having that extra .2L displacement is not always going to give you more power.


now back to the OP, im gonna get on my V6 bandwagon just because i can. while i wont knock the 3S-GTE, its an awesome engine, its really freaking expensive. it will cost you about 3000 bucks just to get the engine. then you have to do the work to install it and if you have a shop do it then thats more. I priced it out and to do a 1MZ swap can cost about 1500 bucks. here is your sign!
