hi got to rebuild my erst2 (it started tapping and knocking), i know the crank as had a regrind to 0.25 under size, cos i did it at work 2 years ago when i took it apart it looks ok and the guys at work say its ok size wise but when i do get round to building it up im going to go efi, low comp pistions, ss rods, bigger intercooler the works really and i want to know if it will handle the power or will it just be better going for a 2.1 zvh thanks for any help
