Im in the process of building my 240 im putting in a r33 rb26 with 3.5" exhaust gt3582r turbo, mines ecu with probably an s-afc, im gonna get a Power-fc later on, with a freshly rebuilt engine at 10psi how much power do you think thats good? Once i get bigger injectors i will raise the boost more.How much HP did you have after you completed the swap, and what mods did you have??

Just an off topic question, why would you have a Mines ECU AND an SAFC? All that is going to do is work against the tune that you have on the Mines. Also, why skip out on the tuning but spend time rebuilding the motor ? To me, that doesn't make any sence.

As for HP, it all depends on who tunes your car, just slapping on parts hoping to make more than stock HP is easy.

well, the mine's ecu was tuned for the stock turbo's since im doing the gt3582r i figured i might need it to make some small adjustments the the fuel. the engine was rebuilt with tomei head gasket and other tomei gaskets, it still has stock internals.

you need to go power FC now.

your safc will not be able to tune out that much airflow.

safc = devil

Yeah the SAFC can only trick the MAF voltage +/- 50%.

It's a good band-aid, but if your spending all this $$$ why???????

Go straight to the Power FC!!!Sell that SAFC and that Mines ecu and your on your way to a PFC.Or chip your Stock computer.

Also SAFC doesn't do anything about ignition timing.
