managed to pull 243.1whp, 209tq untuned with my rb20det. IHI ball bearing turbo, trust wastegate, stock IC, 10psi, 3" exhaust.

then my transmission case cracked and all my gear oil leaked out so i didnt even manage to get it tuned. but i got the transmission fixed and installed my new act clutch.

Can you post specs of your turbo setup (trim, a/r's... etc) What size wastegate? Also is this on the stock 270cc injectors? Any fuel management; ie adjustable FPR?

IHI ball bearing turbo (RHC6) unsure of the trim specs. Trust wastegate (40mm).

i have an apexi s-afc2 fuel controller but it wasnt tuned when i pulled the 243.1whp. no fpr. yes on stock injectors.

very exciting. Thanks for the clarification. Congrats on the whp numbers! Do you have any air/fuel numbers from a wideband when it was on the dyno?
