Hi thanks for the reply,

I actually haven’t fitted the engine yet as I’m going to strip the car and have a full respray top and bottom, the spec of things I have are 2.1 zvh stage 2 head newman cam with solid lifters stage 3 turbo grs front mount, go tech management air tec rad, I’ve not blown any bc boxes still running on the original car is 190hp on 16 cvh at the moment but don’t want to fully rebuild and the blow the original box and have to take it apart again! I’m hoping the car will make 250 minimum when it’s done?
