i have a turbosmart FPR and im installing it to just get the most out of the little rb20 injectors

with a tune, i can install and everything but wondering which fuel line to use....

obviously they have an inlet and outlet on the fuel rail but the inlet coming from the fuel pump

seems to go to the back of my fuel rail (firewall side) and then seems to come back threw

the front of the rail (radiator side) back to the fuel tank. it also has 2 little regulators

just wondering which hose to attach the regulator to?

i cant upload files cause im on a tafe computer so i hope people understand!

cheers

on the fuel rail, unbolt the stock reg. use the adapter you bought with the reg for the nissan fuel rail, that with the new efi hose you have. that goes the the side of the ts reg. the bottom of the reg goes the the tank.

thanks but which reg? front side or back side? i have 2 on mine <BR> and the standard rail pressure at idle is around 36psi isnt it?

Edited by Aaron BNR32 GTS-T

yer, base pressure is with 0 vacuum/boost so set it with the car off then check it with the car running and vacuum hose removed. set it to 43psi for now then when its on the dyno getting tuned you can raise it as required

if you have a dual entry fuel rail can you install the fuel pressure gauge on the end where cylinder 1 will be? as the middle will be the returm and the back will be the feed, thanks and sorry for high jacking.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
