Fook me, this thread's taken on some pace, So basically you're saying, (well some of you) EVEN with a simple Spec like mine headwork will improve it's current state? i knew this BUT i just wanted to know how much and if it was/is worth the cost...

Cheers folks..

PS, Can the 2wd Inlet Manifold allow for 380-400bhp too?? where's it's limits??
