I already did a 'search', and came up with nada! What should the fuel pressure be for a stock 1JZ, w/ a Walbro, Driftmotions' custom (fuel) line, and an Aeromotive variable FPR. Car has a Y-pipe and downpipe, and 3" exhaust, and thats it! Not even a boost controller (yet!) Seems to still be rich at 30psi idle.:icon_surp
Thanks for your help.:icon_bigg

stock fuel pressure should be about 35-40psi with the vacuum line disconnected from the FPR.

Thanks! That just happens to be right where I'm at. motor has a 'flat' spot in the throttle from the dig, till about 5000rpm (in 1st gear) After the shift to second, it almost immediately smooths out ,and pulls pretty hard all the way to the (7000rpm):naughty: redline...gotta' love the 1J!:icon_bigg Woot!:biglaugh:
I'd love to get the 1st gear pull straightened out, but it's not terribly disturbing, cause' the car seems to run pretty well all in all.
