what will happen if i dont have one will it run like **** becuase the map sensor?

 

map sensor will throw a code and you will run in limp mode.....shitty......

 

even on like a 6 pound spring?

 

Yep, as soon as the MAP reads positive pressure around a lbs of boost, it will shut the fuel/ignition down. Run a few check valves inline, I used to run 6 on my other car.

 

so where do i get the check valves from if anyone has some part numbers that would be great caz right when i hit boost it peeks to 6 or 7 then it starts to sputter around 4 or 5 grand

 

you can get the check valves at any pet store or store that sells aquarium accessories...There about 1 dollar a piece..Just got to any pet store and ask them..They'll know what your talking about...There used on fish tanks...

 

then how do you hook them up on a 94 integra

if you can afford it get a missing link, the check valves work but it looks kinda crappy, i still have my check valves on my car, and cant wait to get a missing link, i had to run 3, on my car. its so easy to hook up you should have no problems.
as for the guys at pet stores knowing what your talking about, i called three big pet stores and they were like" huh check valve? is that a pump?" so i just had to go and look myself.
