If all goes right I should have it next weekend. I'll take some pics of the finished one. I am also giving the guy another lower RB20 intake manifold so I guess he can make another one or something. It seems like the best bang for the buck vs the tophat half intake manifold. Too bad looks dont give you HP cause I like the way this one looks lol.http://www.wasabigarage.com/ forgot to post his websight.

Velocity stacks = drool ~!

I'm working on making mine, but mine will be just a top-half that bolts to the lower half. Interesting design on yours...are you worried about torque loss from the shorter runners?

The Guy said $465+shipping.

I'm not too worried about the TQ loss. The Runners don't look all that shorter than stock manifold. . . well maybe a few inches but the top end will be worth it.

Make sure you keep an eye on your A/F ratio. Keep it extra rich and read your plugs to make sure you are getting enough fuel to all the cyls. I gotta admit it looks pretty badass! I wish someone would make a bolt on ITB one for the RB20/25

That whole thing about cylinderrs being more lean is not something you need to worry about. My buddy welds his own manifolds and I asked him about it and he thought it was silly (he has an 11 second talon).

Skyline's are stock that way, and since it's all pressurized with the turbo, they will get decently even mixes of air. I'm not going to worry about it on my setup...can't do much about it anyway unless you have Microtech and can tune each cylinder independently.
