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

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
