What now?

[Onelovee]

Hey yall. Well I just bought my first s13 and love it. I need help in getting directed into the right direction performance wise. ($1500-2000 worth.)

Specs when bought the car: Red top Sr20, oem clutch, greddy front mount, walboro 255fp, t28 turbo (non s15), megan racing dp-exhuast manifold, custom exhuast, hks turbo timer, hks bov, koyo radiator with single fan, greddy boost gauge, rsr springs, and 15X9? sportmax wheels.

I just recently ordered cirsuit sports fuel rail, injectors(think rated to 555), and agency power manual boost controller.

I want to be around 320 but idk what to do next? And with my set up now how much boost could i run safely?

thanks,
Scott

All your questions are relevant to the health of the motor. Best for the SR guys to take this

You are going to need a ECU to tune it up. I'd go with Jim Wolf Technology. Or you need a complete standalone. AEM, Apexi D-Jetro Power Commander, etc.

Is that turbo a 2871R? Only way to see if you get to 320hp is get on a dyno and see where you are at with what you have. Running 'safe' boost can be determined when you get it on the dyno and get it properly tuned. You can't just throw a number out there as it may not be safe for all setups. 15-18psi on one engine can be fine the next one can make it be in pieces.

Assuming you're engine is in good condition, you'll definitely need a tune with those injectors. JWT, Nistune, Apexi PFC, get the best that you can afford with your money. Get your car on a dyno with someone who knows what they're doing. I don't think I saw you mention anything about a Z32 MAF either. That's a must if you want to even think about getting close to your power goals. I'd prefer using a different turbo, ie the GT2871R for your power goals, but to save some money. Just work with your T28 right now. The quest for more power is never ending. You can decide later on what turbo will suit you best as your power goals gets higher.
