Actually, regarding the manifolds I'm not sure if there is a difference between engine sizes. Its whether its Euro 2 or Euro 3 emissions compliant that matters. If your car is Euro 3, it will have cats in the exhaust manifolds. If its euro 2 it won't..

Chris155 on here has fitted euro 2 manifolds (from a vintage 156 2.5 V6) to his 156 (which has a GTA engine) apparently this helps a lot with top end power.
