Im looking to buy an integra type R motor for my 1995 Civic DX coupe. (2 door)... i also am thinking about forced induction ... wouldnt it be better to use a USDM Integra Type R motor for a turbo/supercharger due to its lower compression or is japanese VTEC a lot stronger in the same motor? something tells me i want the JDM one. I also have heard that adding dual valve springs allows a type r motor to rev to 10K without issues. is that true? thanks.
