im using ori sard.

what the the best setting for my gsr 4g93t??? i dun really trust my mech.. lolz


n btw if u guys r planning to put "fuel press" gauges in ur dashboard instead of at engine bay, Plz dun buy "auto gauges" brand.. the sensor adaptor is to big for sard. i had to custom make another adopter for it- > rm35... lolz...

others brand like apexi,defi can fit in nicely...^^

usually there's no problem.just need safc to fine tune it.the con of not having
fpr,u can't regulate the pressure at the fuel rail n u don't know the pressure.

all those fuel pump that u mention r good pump.

i think the bolt-on type is much more durable then the external 1 cos it use
back ur oem diaphragm.con is u wont get the pressure as hi as those external
1 lar but more then enough for 4g15.

yup,bolt on 1 got no meter.if u insist,u can bolt the meter at ur fuel rail.
for 4g15,u need a pressure slightly higher then ur current pressure only.
