:confused: I DO NOT KNOW WHAT TO DO?? I HAVE THE CHOICE OF PUTTIN IN A JDM GSR 10:6 COMPRESSION RATION AND TURBOING IT OR A TYPE R MOTOR 10:6 AND POSSIBLY TURBO THAT. I KNOW FOR BOTH THE COMPRESSION RATIOS R HIGH AND I WOULD HAVE TO LOWER THEM BUT PUTTING IN NEW PISTONS SO I COULD RUN BIGGER BOOST. BUT I WOULD SAVE MONEY WITH THE JDM GSR OVER THE TYPE R. I NEED SOME HELP ANYONE WHO COULD TELL ME WHAT THE BEST APPLICATION WOULD BE LET ME KNOW? THANKS
