Right now I have a nice little LS/Vtec setup with a 8000 RPM rev limit, p&p head, and ITR cams?

 

Oh yeah, I would be going from the 1st gen b16 manifold.

 

Rocket told me the JG manifolds only make power in the extremely high rpm range.

 

It has to make more power than the b16 manifold I have now! The only reason Im going to buy it it cause in the future I wuld benifit from it, and its not too much more than the Skunk2 IM if I get it from Rocket.

 

i would suggest a skunk2.
just my .02

 

So will I actually loose HP & Torque with this manifold? I don't even see how thats possible going from the 1st gen b16 manifold.

 

I would go with the Type R or skunk2 manifold. I have heard that the JG is mainly for turbo set ups, and doesn't t work that well N/A.

 

Turbo did the work for you. http://www.turbomagazine.com/archive...2_tech01.shtml
