The R34 pump will beat the living **** out of the supra pump, but anyway.. I'll be running twin supras cause it's easier for my current setup.

I am running two walbros in parallel, great set up for my T78 . I didnt want to sump my tank so this seemed like the best choice. Got mine from PTP

The stock Mazda FP wiring will only deliver about 11.8VDC to the pump with 14.1VDC at the battery. Rewiring it to deliver 12.8VDC increases power to the FP by about 37%. Doing this has decrease max duty cyle by about 10%.
Worth doing no matter what pump you have.
An it is good to have a fuel pressure gauge next to your boost pressure gauge.

jeez, why bother with any o.e. pump? theyre overpriced and realistically, if a manufacturer was building a 400hp car, why would he ever spec an 800hp pump?????
the walbro itp116 (gss342) pump it good, but doesnt like pressure at around the 420hp level so make sure you've big injectors.
sack it all off, throw a bosch 044 motorsport pump in, will do decent pressure at mid to high 500s hp and they ARE cheaper than apexi/nismo etc. (if theyre not, change dealer)
would you ever genuinely trust a 2nd hand pump from who-knows-where on your baby? id never skimp on the fuel system, go overkill, its the lifeblood or your motor.
