fuel pressure reg

[trbosrule1]

i just got nismo regulator but the adjuster bolt is hitting head do i need top feed rail or can someone point me in right direction

[:: orion ::]

Nismo FPOR doesn't fit the stock location, as you found out.

Easiest way to fix it is rotate the FPR 90* so the adj screw is facingup, then make a new mount to hold it in place.

What do you have done to warrant the need for an adj. FPR???

i am putting t3 t4 set up on my ka next week i purchased afc version two already installed 255 walbro also got vortech12to1 fmu porsche 944 front mount intercooler stock silvia injectors 370cc the turbo is turbonetics the wastegate is a deltagate II with adjustable nine pound spring and i have a custom stainless manifold I just bought a turbo xs high performance boost controller and i have aquired a blitz dual drive blow off . and the off the hook thing is i pieced it all together for less than 1500 bucks no bullshi*. oh yeah how would you suggest i install the regulator if i even need it ii tried to invert like you said but the tail end of the reg is too long also would you reccomend i extend the rail two or three inches and do it that way what wouild you suggest any help would be appriciated. oh yeah if i buy a top feed rail could i still use those 370cc injectors or not

thanx alot:ylsuper :help

USE THE STOCK REGULATOR!

No reason for adjustable, especially with an FMU!!!

Base pressure should be stock!

Sorry to type all caps, but the stock regulator is 1:1, and responds fine to boost. The FMU will do any fuel pressure raising that's needed...

Hondas need adj FPR b/c the run a MAP sensor to determine airflow. We have a MAF, and a 1:1 reg, and it does fine adjusting to increased airflow automatically.

ANd a wordof caution...do not run 9psi with a 12:1 FMU. That's 43.5psi base pressure, then (9 X 12) 108psi on top of that...making 151.5psi pressure in the rail...NO, NO, NO!

You're just begging for a hose to plof off, spit fuel all over, and burn the car down to the ground. It's not safe...

7psi MAX with an FMU, and I would use a 8:1 disc or so...that way you keep the pressure in the rail to an more safe ~100psi...that's what I'd use for a MAXIMUM in the rail.

Trust me...rethink your setup, redo the FMU rate, lower the boost...else you'll blow the motor, or burn up the car.

Stock MAF is maxed at about 7-8psi with a T3/T04E anyway, so nine may be too much to meter...

Just food for thought...

with all the money you saved you can get a JWT ECU and then you'll have your timing covered too and that FPR and fuel pump will be of some use.

You don't use a FMU with bigger injectors...The AFC and the 370's is all you need.
