i got a lsvtec in a 92 hatch i was told when i was building it that if i put the ctr pistons against a gsr head i would get 12.5:1 compresion
my question is what psi should i run (B&M FPR) and what settings should i do on the vafc
thanks for your help

 

I couldn't tell you all ur settings because only driving it and going by feel or dynoing it are going to give you good results.... One question tho, are you aftermarket injectors and do you just have a stock GSR head??? Just wondering, Latez

 

still using stock ones and the head has just been cleaned up jg valves retainers springs and skunk cam gears
nothing much need to get an ect gauge

 

EGT ?
you need to tune that bish......

 

how am i soposed to tune it with out an egt?

 

run about 42-46 psi and high octane gas.

 

dyno.

 

EGT doesnt help anything.

 

CR w/ CTR pistons is 12.76:1. You'll need to get it on the dyno to know what fuel pressure. I've run this set-up before. Also w/ the V-AFC, get that biatch on the dyno, don't try to cheat and do it the cheap way, becuase it doen't work like that.
