turboing rsx
 
i am turboing my friends rsx and now we have everthing..he can not afford hondata yet...so we are running drag fmu(which i know sux) and only 5 lbs of boost...since there is no hondata is it okay to not change timing and just gap plugs more...and run richer?

What are you doing to the fuel system? If I remember right doesn't the RSX have a return-less fuel system??

Just thought I'd throw it out there.

you should at least try and get an afc(hack), its a little bit better and safer then an fmu....

k series motors run a returnless style fuel system. It is not wise at all to try and run a fmu on a car like that. as the others have mentioned, wait for the K-pro. It will save his motor.

We have a turbo RSX in our group of car running a greddy turbo kit, hondata kpro, thermal exhaust, quaife and a spec clutch and the thing is tuned so precisely and is wickedly fast

Because on a normal car the fuel pump circulates fuel up to the engine, threw the fuel pressure regulator, and back to the tank . SO any fuel that is not used by the engine then goes past the fuel pressure regulator and is returned to the tank. A FMU raises the fuel pressure by restricting how much fuel returns to the tank. If no fuel ever returns to the tank it cant change what the fuel pressure is. Thus it is worthless.... Get K pro

best advice. Or get the hack if your buddy can't wait any longer. I would just wait and save money most likely he has a pretty new car and K motors dont come cheap
