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.

I believe that what changes is the water passages. ATS racing makes the headgasket designed for use with only the 1997-2001 blocks. You can modify a headgasket or drill the block as others have done before.

Here's a link: http://atsracing.com/Parts/Details/E-5S-HEADGASKET

Working the head of your stock 5S-FE is not a bad idea. There's dyno sheets around of 5S-FE engines with performance cams installed shooting around 150whp.

There's also a build of a 5S-GE (5s block with a turbo 3sgte headswap) running e85 and an EMS and he's doing 180whp. If you think the cost of a head, custom wiring, perhaps even a completely standalone ECU, is worth 30whp then be my guest.


You're looking for power, a full 3SGTE with a couple thousand dollars will give you that with the least headaches. V6 without forced induction will never compare to an upgraded 3S. I'd rather a turbo 5S than a V6, too. It's a lot cheaper to do unless you have the means of fabricating the custom mount, the accessibility to a cheap V6, and the tools required to swap the engine.
