Im installing the FAST90/90 this weekend and was wondering what or if I have to do anything about the coolant crossover tubes??? I didnt recieve instructions but managed to search my way through for torque spes. It has been installed before so the map sensor hole is there. I have to bypass the coolant crossover for the throttle body. Is there anything else before i go at it???? thanks ahead of time.

I think most people run the LS6 steam vents on those as well.

You need to the coolant crossover tubes from the newer engines. Either that, or you can beat the hell out of yours to flatten it out.

I also think you could cut the existing one, and either block it off, or run a high temp rubber hose under the intake, to connect the two.

Like they said on the coolant tubes. If you want a instruction sheet you can still get a copy of the instructions on the fast Website : http://www.fuelairspark.com/Instructions/Files/147.pdf

The other very important thing is to change the Valley cover bolts with the button head bolts, otherwise you will crack the intake!!!

^ Yeah... That's a good one too. Forgot about that.

you can run a ls6 coolant line front and back and connect them together up front.or carefully tap down on the stock ls1 coolant lines until it touches the valley cover plate.use a plastic hammer and a piece of wood.there is more room under a fast 90/92 intake for coolant lines then a fast 102 intake.

I do have the valley bolts, thanks for the heads up.

sbsrkh thanks for that link, I looked all over the website and missed it somehow, I even called and he just sent me 102 instructions (very similar) lol.

I guess ill have to work on those coolant lines i guess. thanks again guys
