Hey guys, I have a 91 Integra with a B20B and I reused the B18A1 intake manifold on the B20. I am wondering what would happen if I don't have any coolant running into the fit valve? The reason I ask is because it keeps on leaking and one of the fittings I have blocked already on it so it DOES have coolant running to it now but I want to totally disconnect the coolant hose going to it so that there is absolutely no coolant going to it and into it. Would I notice any changes in the way it runs when the engine is running or when it is warming up?

Your RPMs would stay normally low at cold start ups. Shouldn't affect anything else.

Man that would be perfectly fine with me.

it may stall on cold starts. the ect sensor will still inform the ecm of the engines temp. it will then adjust fuel accordingly. basically, you''l be getting a dump of fuel until the car warms up. the ecm doesn't adjust for the lack of a fitv. if you don't hold the idle manually, it may flood. i've been noticing this with mine in the colder weather

I am Also Driven a 1990 Acura Integra with a B20b Swap running the stock B18a Intake Manifold. I cant find where the hose on the left of the F.I.T valve goes to???? is it even able to hook up or am I just not seeing the spot where the second hose goes???
