are you going 2wd or 4wd
if 4wd you will have to use some of the 4wd components-and should really use a 200 block
if rwd anything that fits will do-if going stage 3 and above the smallest i/c would be a 4wd but used rs500 copies are cheap enough
some of the water hoses are different if using a swirl pot in front of block
a good fast road cossie is stage 1 on standard injs etc-any more than that is really overkill for the road/pocket imho
to do the basic job anything from level1/6/8 will do but the better the ecu/later the more functions that can be added
standard boost is very low[perhaps a bit slow]-my saph cossie runs this,and its night and day to my stage 3 3dr
