Have a look on Projectpuma web site matey. There is loads of info on there.

When i fitted the 2ltr tb i had to take the inlet manifold off and bore the hole out cause its the same size as the standard tb.

It took me about 1.5 hours to remove manifold bore out and fit the tb. You have to swap the throttle position sensor round cause it catches and you have to swap the throttle linkages about. Its easy to do.

Im 6ft and a bit. I fitted a set of bucket seats so it gave me more room. I used the standard seat brackets and bolted them to some strips of metal.
