bro..if u service ur TO4B.. U STILL GEt ur to4b...the main thing money spent no matter what..
so my suggestion is..build up ur engine..using stock turbo 1st... then later when got xtra money buy new turbo..if u r planning to use big injector ..u need an EMS.. i heard that using VR4 bLOCK WITH evO HEAd need some modification if not, will experience oil press problem..so turbo easy to kong la..
i've read it at DSM forum too.. using evo head into vr4 block can give the oil pressure problem to the engine..anyone had experienced this problem?..then what modification must be done to evo head to ensure the oil pressure is in good condition?
