Is it unusual to run a Genuine Std Rb30 pump? all this talk about pump failures is making me think i should definately go external.

The RB30ET blokes have always used them.

There was a bloke on here running a td06-20g setup running the std rb30 pump. Sitting on the rev limiter at 7500rpm during massive burn outs and it hasn't let go.

Apart from that I really don't know how far the std pump has been pushed. These days calais turbo will be full of the dohc pumps where as before back in the early days of the rb30et's they would have no doubt pushed the std pump hard.

What did Bu5ter do with his rb30det setup? He hasn't had any issues that I know of.

Hi guys,

I've made a few changes including the phone number as I spent all day talking to people in Bombay trying to change my phone plan etc. I've also got out of general reconditioning but I'm still doing this stuff. You can get me on 0448 826256 (bh) if you need a collar. Sorry moderators, I'm not trying for a free plug, just getting the details right. The address is still the same, so is the website though very underdone due to time constraints.

Cheers,

Greg.

dunno, but the drive on the RB30 pump is less than half of that on the RB26!

Go external mate :pirate:

Cubes: It doesnt mean less flow it means less drive width.

The rb30 smaller internal gears do mean less flow.

Big chunky teeth take bigger bites of the fluid. A bit like a small turbo compressor wheel and a large one.

I took a heap of pics of dohc and rb30 pumps when I was doing my motor. You want to see how pathetic the rb30's internal gears look to that of an rb25/gtr pump? :)

Thats interesting RE: R33 Pump internal gear width.

My pump had the internal gear being thicker than the external. (Unless its just the angle of your pic)

Both gears were also thicker than the rb30 pump gears I had on hand. Maybe my rb30 pump was n/a.

I did take measurements and should have them laying around somewhere.

I'd say you will find the actual rotors of the gear are the same width, in the photo the centre gear sits up because of the hub that locates the gear in the pump. The VL pump I have in the photo may have been a turbo one, I can't be sure, it was just lying around when I thought I'd compare a few different ones.

      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.
