Im soon going to build a ls/vtec, i have a gsr head, with adjustable cams and pr3 pstions with Ls rods and crankshaft. I also going to chipped a p28 ecu. I was wondering what horsepower i might be getting and compression rate.

 

Here is a good compression calculator...http://www.c-speedracing.com/howto/c...c/compcalc.php.
