Hi RobertB... I have a bigger intercooler yes. It is a must for bigger gains, the stock one is piddly! I had her on the running road a while ago now, But I have an issue with my cylinder head. I'm not happy pushing her too far until I get it sorted. It has worked out far cheaper to buy a second hand head, recondition it myself, then fit it, than it was to buy a reconditioned head. It's probably nothing but I have to know the engine is 100% before i go beyong the 250bhp mark. The bottom end I know is perfect.. I built it and I have only done 30k miles since with it being looked after all the way.
