Guys ive got an R32 GTST. I have a choice of 2 FMIC's. One is 600x300x76 and the other is 600x300x100. So far current mods include 3" mandrel zorst, dump pipe, rebuilt and hi-flowed turbo, rb26 cams, gtr injectors and bigger fuel pump. Im just curious as to what would be the better one to use?
Down the track im looking at fitting a TD06-20g or similar with a manifold, etc.
Any ideas comments?
