I've done a few searches and still unsure which route I'm going to go. If I spend an extra $500 I will have enough to build an iron 402, or should I just stick with the 370 and use that $500 somewhere else? My real questions for determination, with the same turbo (like a 76mm), how will spool times compare/contrast with an a4 trans throughout the power band? And if I can get both engines to the same amount of boost on the same turbo, by how much can I expect the 402 outperform the 370? Or will the 402 really only be good for bragging rights and a minimal gain? A setup that kicks really hard in the midrange and carries it out through the top end would be perfect.

Also, I'm unsure if I'm going the turbo or procharger route. I like turbos much more but a D1SC would be an easy install and quite reliable with an 8 rib setup. But I'm heavily considering a RM right now to make it much easier on fabrication, keeping the ac, and keeping underhood temps down; only worries is the oil lines and ground clearance. Perhaps a c6/truck manifold setup if I can find someone local to weld/cut some steel up. My ideal static compression will be around 9.2 and wont be necessary to go over 15psi.

If you are plannig to run a 76mm Turbo stick with the 370ci engine. There are some T6 Flanged 76's tyhat will work on a 402ci setup, but that size engine is better suited to a 88mm or larger turbo.
