you need a custom downpipe, you need to put in a fly by wire throttle pedal. VR gearbox as mentioned. Wiring needs completly re-worked back to CE2. lambas, etc etc turned off (you have c2 to do all that). Aint gonna be cheap to get it all sorted, thats why Ive left it. Including engine ive worked it out to be about 2K to do it properly.
