Whats the main difference between the B6 and B7 exhaust manifolds. Is the bolt pattern different? I know the B6 and B7 heads are very similar, but the 1.8T turbo manifolds and turbo upgrades are easier/ cheaper to get then the 2.0T. I was just wondering if i could get a K04 turbo and turbo manifold and make it fit on my 2.0T... any ideas?!?!
