Alright, I've got a few questions about rebuilds on rotary engines. First of all, I heard something about using FD housings when you rebuild. What good would this do for you? Next, is there anywhere that has a complete tear-down and rebuild on how to do one or is there a video I could buy that would explain it in more detail? Also, I read somewhere that you can't use an S5 engine in a S4 car because the balance is different on the eccentric shaft? I'm interested to know because I want to do a turbo conversion on my GXL, and obviously would like to start with the better engine. I know the S5 has more HP and torque, but why is this? Lighter weight rotors?

Boostmaniac

The S5 has a more advanced turbo, higher compression rotors that are also lighter.

I think they also run more boost but I do not know for certain if that factoid is true.

pretty sure you need a different harness in when putting a s5 engine into a s4

a LOT of people do it though its a very good upgrade to do

also look at street porting

^ he has the best prices and is fairly close to you also check out his site for lots of info on rebuilding

EDIT: looked at the guys location above me when I said fairly close

you can ship him in your motor since your not really close to him at all
