Hello guys!!

Its been around two months with my CA up and running and I want to start getting the best perfomance out of the stuff I have.

Stock injectorsChipped ECUGarret T2810 PSIWalbro Fuel pumpHKS filterPressure regulator (borrowed)Boost gauge and oil pressure gaugeGot the CXracing pipekit with FMIC3 inch straight exhaust pipeTein suspension

Now my car runs very rich but is not properly tuned and what i want to do is make a list of things i should get to get the best perfomance out of all those things

Thanks for the assistance, just a little new to the CAs and want to start up with the right foot before thinking on more HP.

Good platform to work with but Depends on what Stage is the Chip you have. You could maybe take it to 12 PSI but it would be a good idea to get a Wideband to monitor fuel mixture.

If you can get someone to do a descent tuning on S-AFC or Emanage, you can take it to 15-16psi with 450cc or 550cc injectors. Good enough to give you a permanent grin when you drive it.

Thanks! well I dont want to get more boost just yet, I wanna try to get the best of what im currently running, now some guys here is selling me a SAFC 2 but i dont know if it would make any difference without the wideband?

As far as the chip, i got the engine with that ECU already chipped so dont really know how is setup, i know i dont have a fuel cut and that i can take it up to 8000 RPMS without cutting but thast all I know.

Thanks!!!!!!

So I take it you installed the SAFC and got it tuned? I suspect you're near the safe limit of the stock injectors, so I wouldn't turn the boost up anymore till you get bigger injectors, preferably 550's and a Z32 MAFS. That combo with 18-20psi should get you pretty close to 300whp with a good tune.

Yeah I got a SAFC and a wideband, im thinking on staying there for a while, but im currently looking for the MAF and some RX7 injectors,I had a set but sold em hehe.

I gotta start working on the looks of the cars cause it looks like crap right now but at least im driving safe.
