S14 SR20DET how much boost to run? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

rps13_fastback · 02-04-2005, 10:30 PM

My setup currently is:

S14 SR20DET
30x12x3 custom FMIC
480CC S15 injectors
Walbro 255lph HP fuel pump
Z32 MAFS

HKS filter
HKS downpipe
Apexi N1 catback exhaust
Megan Racing test pipe

Apexi SAFC2 fuel controller
Blitz DSBC boost controller

My question is how much boost can I run safely with my setup, or how much boost is the t28 efficient to? Also how much power would I be making?

Thanks

dude, you really otta search first. This stuff is like every other thread.

However since I'm bothering to post....

you can run up to about 1 bar without damaging the turbo.

Depending on how strong your motor is, you should be making about 250-260rwhp with it. Maybe a little more, maybe a little less. There's a lot of variables.

I did a little searching and heard mixed reviews... some people said you can run ~17-18 PSI safely..

keep in mind I have 480cc injectors, walbro 255lph fuel pump, and z32 mafs...

also I read some people making around 280whp or more.

This is not s13 sr20det, it's an s14.

With all the bolt-ons, 600cc injectors, power fc, stock mafs, I made 285/310 on a dynapack. This was at 18-19 psi dropping to 15 psi as the rpms climb. Intake temps are surely insane, but I have no way to measure.

Make sure you tune the car well. THat's what really dictates the result and safty of your motor.

Just start with it at 20psi and work your way down from there.
