I need GM #38 injectors but tehy are way too expensive so i was going to use SVO #30 will these register as 36/38 in the LS1? Any suggestions were i can get injectors cheap? The 30s from SVO are orange red right? Thanks

 

yeah its about 36 at the ls1 Fuel pressure..

the 30's are red tops. the orange are 19's blue is 24

 

what should fuel pressure gauge read.....mines at like 60psi...is that bad????

 

stick6shift,
60 psi is perfect.
here is a dyno graph of mine with bad fuel pressure at the top end.



hope that helps.

 

Go on eBay. You can find some 30# injectors possibly under $200
