I agree that the 3071R .63 will spool faster and make more power than the 2871R .86. I think the .86 housing is just restrictive. Ive always been curious of the GT2871R w/ .63 T3 housing. Might give the same top end power of the .86 with the spool that it lacks.

370cc can max out with only 10psi pending on the setup. When i dynoed my stock block w/ 2871R .86, Greddy IM, and HKS 264 Step 1 Cams, I was doing 315whp @ 14-15psi.

INeedNewTires, i believe you can hit your 400hp goal if you get a new Intake Manifold and some kind of Tubular Manifold. I like my Ichiba Vers II Manifold. Same design as the Tomei but half the price.
