Hey,

Just wondering how far a standard r33 rb25 (ser2) fuel pump will go?

Currently running the following setup: 3" exhaust, FMIC, std turbo, std injectors, remapped ecu and 12 psi.

Will it handle this ok?

cheers

Probably yes, but due to the age of the car and the pump i would be looking to invest in an upgrade at some stage just for safety anyway.... They are cheap and easy to do so no reason not too :)

hmmmm good point.

Whats the better setup in a r33?

Bosch 040 and remove the sock, mount pump as low as possible

or

Bosch 044 and adapt the standard sock to fit?

i did a 040 years ago and remember not being certain that I had it mounted as low as it could possibly be and from memory i recall seeing a 044 mounted in tank with factory sock....

How much power are you aiming for mate? Drop in Walbro will be much easier for lower power levels....

My 044 is mounted with rubber on the bracket and has a sock, better than the 040 option but depends on how much you actually need?

ive had 2 walbro's now, the 255Lph handled 260kw so that would be fine.. quite cheap too. I didnt want to take chances with the fitment, tuner fit mine in well under an hour so worth it to get done right first time.

Walbro have a good rep, with the Bosch pumps Ic heard good and bad things. Seems they can go either way depending on batch etc. I recently bought a Nismo and couldn't be happier. I'm letting a GTR pump go. PM if interested, I want it gone!

Not saying they're all terrible, but as I said I've heard a few can be dodgey and have ha to be replaced. Read it in a couple of threads here on SAU, but as I've said I'm not commenting on personal experience just what I've read on here.

I've had a Walbro in my tank for about 4 years. I have a 044 as well - haven't heard anything bad about them except they're noisy as!!

Mine is quieter than the 34GTR pump I had.... All about how you mount it etc

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
