just saw some errors i wanted to point out...
1. ls pistons dont have domes.
2. shorter gears dont have anything to do with final drive. anything. and all type r boxes do NOT have the 4.7 final, only 98+ spec JDM integra type r gearboxes do. And they really suck if you ever have to drive on the highway. Put a lsd equipped b16 and a usdm ITR gearbox in the same car, and noone on here would be able to tell the difference. i promise.
