i rebuilt my engine 4G63T and put 9:1 comp pistons with the Bolt on PTE T3/T4 Hybrid turbo and a grip of other stuff that wouldent be relevent to this question. I was wondering if it was possible to break in the engine with the stock fuel system (injectors FPR and pump) as long as i keep the engine under 4,000 RPM's and keep the turbo from spooling? would that be safe or is that not recomended.
Thanks for your help
