5s-fe 3s-ge head? Options

[myloth]

The 5s-fe and the 3s-ge,3s-gte are the same motor with different heads no?

Then why is everybody so juiced to swap in the 3s-gte?When couldnt use a 3s-ge head from late 90s on a 5s-fe and get about 200bhp without a turbo?

Or am i missing something?

I'm basing this on a 2.0l 3s-ge from late 90s having about 175hp and putting that head onto the stroker 2.2l block seems to make sense?

People talk like the 5s-fe is a different engine when its just a different head and longer throw crank?


Or could even a 3sgte head work without the turbo?

any time you try and bolt a different head to a different bottom things always get a little strange. I don't know if anyone has tried to do this really but I can imagine its because the 5S-FE internals cannot handle the revs and power that the 3S-GE head is designed.

I really have no experience with the S engine but with the 7A-GE and 9A-GE there's a lot of different and hilarious things you have to do to jimmy the thing into working condition and almost every build has different specs even though its supposed to be "bolt on"
