What do I do about all this vacuum operated stuff? I've heard you can get away without using the vacuum pump by using a typical little check valve in the vacuum line. My question is where do i put said valve? Which vacuum lines will need one? I would assume the line running through the firewall on the right side will need one, but i'm really not sure where i'm supposed to put these things...

Az4u2c- Just adding a check valve or 5 wont take care of the issue. Adding a vacuum pump would probably be a good idea but you also will have a constant vacuum between the intake filter and the turbo inlet. It is pretty easy to tap into an intake pipe with vacuum fittings. I used fittings from Vibrant but I am sure there are many others out there.
Climate control, brakes, FPR, Cruise if installed, Smog crap if installed, evap canister crap if installed. I suppose it really just depends on what you are leaving in tact. So there is the question really...Just stand back and throw money.

Ya, there is a brake booster on the NAs. It feeds directly to the intake plenum. Hmmm...on the turbo does the vac come from the vac canister?

No but really, do you want positive pressure going to the booster? The turbo models come stock with a check valve inbetween the booster and the plenum.85 Z31 6.0 LSX turbo 766whp/792wtq

hehehe...sorry man, I misunderstood. :? That was kind of funny though.
Just curious though. So the Turbo and NAs grab vac for the brake booster from the same location? Not something I ever had to think about before. Interesting. Apparently it works fine for both applications though.Just stand back and throw money.

I dont know if running pressure to the booster is a BAD thing but I cant imagine running 20psi to it being a good thing.
