I'm collecting parts for my 95 GSR engine rebuild now and plan on doing it within the next three months. CTR pistons, CTR Intake cam, ITR Exhaust cam, AEM pulleys, adjustable cam gears, AEM short ram, HV oil pump, P&P (light job for a driver) and eventually header and exhuast. Is this worth having Hondata tune the car? Should the ECU just be left stock? If it's not going to do much for the cost, I'd rather not. But if they do a good enough job to notice a difference after minor mods such as these, then I'll go ahead and get it done... Opinions?
