My friend has a ls/vtech ls stock block and a gsr head w/ a turbo replica that you buy from ebay he says he is pushing 5psi of boost. i have a LST stock block w/ a rev-hard kit and im pushing 7psi and his car is much faster than mine. can some tell me if the gsr head has alot to do with it or what?

 

that and his egay boost gauge is probably 5 PSI off too.....


but yes makes a considerable difference. plus which tranny is each using?, car?, rev limit? driver?

 

he is got a 99 gsr tranny and i have a 96 lsd tranny b16

 

yes , vtec motors will make more power, but not torque.... just turn the boost up man i ran 13psi on my stock block ls for a long time!

are you tuned?

 

no!!!! stock block w/ b16 sir lsd tranny willl this tranny help

 

will the ls head hold more psi than the gsr head

 

maybe you should go take a look at my post as i too am getting good responses for a similiar question
