having sorted the phase 3 kit from gav i have been looking at a custom intercooler - which i have happily come to a conclusion on. I have 2 sizes that are do-able.
A) 4.9 ltr core that sits 90% open to lovely cold air feed.
B) 7.4 ltr core that sits 50% open to lovely cold air feed.
(% are approx )
so which do i go for? i know roughly speaking bigger is better but whats the general concensus? - before i phone gav and try and order one
