My old setup:
K24a1/k20a2
04 Type S Trans - stock
Rotrex c30-94 ~12psi
RBC with stock tb
Crush bent mild steel exhaust
650cc precision injectors

Tuned by Chunky made 377whp/250tq on Mainstream Performance's Dynojet.

Had a fuel issue and couldn't rev past 7,000rpm. That later got resolved and made what I estimate to be close to 400whp on 93 octane.

New setup improvements:
ITR chassis
C38-91
All In Fab header with 3 inch collector
Better exhaust (will be 3 inch and mandrel)
RSP intake manifold
DPI 1200cc injectors( plus entire fuel system upgrade)
E85 at some point


I don't know exactly what this will make but I see it hitting 500whp easily on E85 on a Dynojet.

If you lower your vtec crossover to 3000 you will improve your low end a fair bit.
