The isis intake manifold for the rb25 if I am going to keep the stock rb throttle body does the greddy adaptor work?does the manifold come with the gasket?

I on RB web site they have the front pusher flexalite fans, I really do not feel like fabbing any work will they flow enough as pushers?

The ISIS manifold is basically a Greddy copy, so the same rules apply if it needs an adapter. Whether or not it comes with a gasket is beyond me, if not just smeer a thin coat of RTV on the flanges before installing, and it should work fine.

Cooling on RBs seem to be a sensitive subject in a way because what works for one person doesn't seem to work that great for the next guy. In theory, the fans should be able to push enough air through the front when sitting still to not overheat until the car is moving again to help push air through the front. If running AC while sitting still, the extra heating will reducing cooling efficiency and cause the engine to run a bit hotter due to the condensor's heat passing over the radiator as preheated air. As what many have said already, build air ducting so less air goes around the radiator rather then through it.

No clue about the mani, but hang on a sec before you order the fans. Stec had a NASTY set of fans pushing on his car. You could hear them going over the car at idle, and he has BIG cams, a loud exhaust, solid motor mounts, yada yada yada. The cars shakes at idle and you can still hear them. He has a low temp thermostat and this thing goes through traffic in Okinawa with the a/c going and never gets above 70c. Now he's got a pretty good radiator too, but the fans kick a**. I'll ask him what they are.

I just went to jegs and got their brand 13in pusher/puller fans. I never had an issue track or daily with one or two on.

My setup was 2 13in pusher fans (1490cfm each), cx racing radiator, 300zx low temp T-stat and it worked/works great.

One thing I am going to add is a swirl pot. I know it'll help out alot.
