2wd manifold produces more tourqe then the 4wd manifold, i run a 2wd one on my 4x4

yup straight swap but u wll need a turbo dampner/hanger thingee.

thought it was the other way round (like havin a smaller bore exhaust)

2wd is a better flowing and makes more power!!!!!

you can swap 2wd manifold for the 4x4 or vice vesa but you will need to rotate the compressor housing of your turbo and get a turbo damper
i presume you are going from 4x4 to 2wd
if so what spec is your engine

yeah 4x4 to 2wd, was just thinking if there would be any benifit as i have got the head off and 2wd manifolds seem cheap enough

as for spec at the moment its on greys, T3, Magnex exhaust, the head is going away shortly to be flowed, and i am going to fab a bigger intercooler when i can be arsed and when i have decided how big

4x4 manifolds are better up until 450bhp, then the 2wd one is better

what does your car run like with the greys, seen as you still have a t3 and standard cooler i cant see you running big boost so im wondering why you have greys and not just a set of greens, is it lumpy in the morning? how bad is it on fuel?

I was told the turbo sits slightly higher on a 2wd exhaust manifold than on a 4wd exhaust manifold which would effect exhaust height and the plumbing for the oil and water pipework,can anyone else confirm this?
