5sge Options

[gallant17]

anyone here done this head swap im looking into it. (i know its not just a matter of nuts and bolts but looking for some more input)

Like was said, there are some people who've built the 5s, but the problem you run into is that there just aren't many places that sell race quality kits for that motor.
On the other hand, motors like the 3sge, and 4age have loads of more potential right from stock and there are many places to get all the racing parts you'd want.

This guy's spent a lot of $dow on the 5s only to have it keep breaking. It seems the 5s wasn't built with an oil pump to handle more power. And in this case more displacement doesn't necessarily mean more power. The 5s(2.2) has a larger stroke than bore which is good for fuel but makes it rev slower, the 3s(2.0) is a square motor, and the 4a(1.6) has a larger bore than stroke. Those fundamental dimensions have a great effect on the natural behavior of the engine and so the 3S or 4A with the GE head already on it is ultimately the better choice. If you compare Because you would have to change the computer and a bunch of wiring to put a GE head on a 5S anyway so you will be better off putting the whole 3SGE in there since it has more upgrade potential. And the 3SGE bolts right up to the same transmission that comes with your 5SFE.

This is my own personal summation of this topic which comes up often. The 5SFE was originally the Camry motor and with the valve angle of the FE head the motor can't breathe faster than 6,000 rpm and was not made to spin higher than that. With the GE head you can spin it higher and higher and it will keep making more power, as long as your internals are strong enough.
