1) Which STi versions have the fifth injector on top of the intake manifold?

2) Which STi versions have the intercooler waterspray?

3) How to get rid of the 110 mph speed limiter on Japanese ECUs?

Cheers,

Marnix

RA has 5th injector
And AFAIK the 5th injector is redundant on road versions
I can supply a remap that will increase boost to 15.5psi or 16.5psi (depenadnt on ECU) and get rid of the limiter.

Thanks guys. It seems only the MY95 WRX (type RA) STi Version 1 has the fifth injector. And MY96 does not, but that has the water spray for the intercooler.

Anyone know how much boost the various STi versions run?

Anywhere between 11.4psi and 13.5psi.
The later the higher (only talking Pre96 tho').

P.S Just cause it's an RA don't always mean it's an STi.
