STS Kit In Finally (need help)

Ok I just got my standard kit in with a blow off valve. I just wanted to know if there would be anything else I may need besides tunning? I want to run 5 PSI, do I need anything extra? what about if I want to run 8 PSI? any info will help thanks, John 2002 Z28

8 psi is fine to run on a stock motor. You don't need alky injection. You can run more than 8psi if you do get methenol injection or customize an intercooler to it. Before running 8 psi though (assuming you have a good tune) I'd suggest getting bigger fuel injectors. I'm running 42# ones in my car. What kind of spark plugs are you running? You need to run a cold plug. I've got NGK T6 iridiums in mine. Eventually you'll need a bigger fuel pump.

If you are going to run anything over 5 psi, get something to cool IAT's (FMIC or alky). Matter of fact, it's not a terrible idea to run a FMIC even at 5 psi. Just make sure the tune is on! Enjoy.

well, I had to put a new clutch in within the first week, replaced the limited slip rear, gears, added axles, alky injection then added a boost controller for 8psi. Then I blew a head gasket which turned into a heads and cam swap, injectors, oil pump and a hellavalot more money then I ever planned.

Make sure to get at least a set of 918 valve springs when you can. I'd stay at five # for awhile seeing as my car is set at 5 but has been over boosting to 7 in the winter. Oh yeah and the clutch went after 2 weeks and I'll need a 12 bolt soon.
