Anyone boosting LS/VTEC
First off- Don't respond if your hating... We've heard it all before.
Im building my LS/VTEC from ground up, NO SHORT CUTS and Im wondering:
what compression pistons to use for 10-12 lbs of boost. Im sure putting the different head on will change the compression, so thats a factor... But how can you be sure about the ideal ratio???
I plan on running it N/A for the first couple months, then put the boost to it after it feels all nice and cozy in its new home...

Re: Anyone boosting LS/VTEC (Incognito)
People quit giving their "constructive" critisism when they find that people can actually pull off some good stuff with the setup. And theres more to come(less bugs in the system after a little tuning)...
You didn't list any info for compression ratios. And I assume that the car is a daily driver? Also, why haven't you done any adjustments to the ECU- that can really make a difference...

CR is 9.2:1, which is about what GSR head on LS block gives.
Stock ECU w/VAFC, 370cc injectors.

Re: Anyone boosting LS/VTEC (rondigs)
ever tried building a vtec ls?
use GSR block, ls crank, internals head ..., this will give you a torquey motor with good head valvetrain and oil squirters, you can ugrade any of the rods and pistons to whatever CR you want. all you lose is about 60cc of displacement. this will be a high revving ls.
