use a s2 exhaust, manifold and down pipe.

and get your hands on a ofab fez turbo ecu and on the ecu connector :

1) At the ECU, pin no. 27 (marked on the multiplug, brown wire) needs moving to pin 8, which is empty (this is the CO adjuster signal wire).
2) Pin no. 45 (brown/yellow) needs moving to pin 27 - this is for the MAP sensor.
3) EDIS Module pin 2 (blue/yellow) may now be disregarded as it is not used by the 0FAC ECU (pin 28 on ECU).


did this conversion last week end. still got to get an ecu tho so its not all wired up.
you can use an ofac ecu aswell but the ofab is easier. but can only use a 2 bar map sensor.
