As long as it's a bar and plate intercooler it'll be fine. Not a a tube and fin. Doesn't have to be an expensive one either. The spec you Need to get somewhere around the 300bhp/300lb/ft is the intercooler,
630cc injectors, 3" exhaust system including the down pipe. And a meg mk3 250/265 T15 turbo.
I have a cheap intercooler but it's a tube and fin, so the charge temps creep up quickly, still made 304.8bhp and 298lb/ft. It's ok for driving about but no good for the track!
Didn't know until I had it mapped. Learnt a lot along the way.
