FMIC piping

[Clubman S]

Hi Mates


i was installing a FMIC and now need advise on Intercooler piping diameter, should i use 2" or 2,5" piping from turbo to intercooler and to intercooler to manifold?

everything is home made due space (Mini Clubman with a 4EFTE engine inside!)

well from my experiences and from what others tell me u make the pipe the size of the throttle butterfly (a stock 4efte has a 50mm (2 inch) throttle plate) so 2 inch intercooler piping would be the go..my 4efte runs 2 inch on the cold pipe and my hot pipe which is very short is 2.5 inch ( i wanna change it to 2 inch...2.5 inch was all i had)
