Fuel pressure question

[jandysil80]

About to install a S15 turbo, Z32 maf, 600cc injectors and an Enthalpy tuned ECU on my s13 blacktop, do I need to up the fuel pressure, or will the stock regulator work? Any suggestions? thanks

Stock FPR should work fine - Im going to assume you have a walboro or other upgraded fuel pump right?

In my experience with enthalpy, you might want to get an SAFC to make some fine tuning adjustments.

I to advise a AFC and wideband.

Enthalpy says to use stock fuel pressure.

sweet, thanks for the info, I didn't know that Enthalpy requires the use of the stock fuel pressure.
