Dunno if this has been discussed already but i'm looking to convert my R32n to an external fuel pump cos i cant be farked buying a new internal pump for it. I have a good VL turbo pump out of my DR30 (upgrading that car to bigger pump) and was wondering if many people have done this already. I'm a mechanic so i'm doin it all myself (obviously) and just hoped someone has any hot tips.

Cheers Michael.

Too hard as in cant be bothered and dont wanna spend money on it. If i was to put in a surge tank i would have to buy or make one then buy a low pressure pre pump for the tank and i'm not keen to spend anything on it cos need the money to build the motor in my DR30.

As i said its my daily driver so i'm doin it all on the cheap and effective.

Any tips on the actual job i'm doin would be much appreciated.

Cheers Mick.

from memory the VL turbo pumps need to be fed into (be at the bottom of the tank with a gravity feed into them) which means that they cannot suck fuel out of the tank.

to do that on the 32 you would need to modify the tank to have an outlet at the bottom to gravity feed into the pump.

how is it setup in the dr30 ?

Interesting point.

I'm not really 100% sure at the moment but i reckon it feeds off a big hose comin out the top of the tank. Could be wrong so dont quote me on this. Havent really looked under the car for a while. I'm pretty sure if i mount the pump low enough in relation to the tank it should half by gravity feed out of the tank once the flow starts. But then again it might not.

also are you 100% the pump isnt using another as a lift pump direct into the VL pump?

VL pumps DO NOT like running dry at all, had 3 fail in a sprinter (ca18det) due to the surge of the std tank - fixed by welding in a small collector tank area in the bottom of the tank.

Yeah didnt end up using the Vl turbo pump. Once i got the car on the hoist and had a good look around it became too hard so i lashed out and got a bosch motorsport 040 pump for it. Didnt realise how cheap those pumps are (at least cheap for me cos we are bosch dealers at my work WOO HOO).

Made a massive difference to the power output of the car now its not dropping pressure anymore. I would highly recommend them. Was pretty easy to fit. only minor modification made to the mounting in the tank. Lovin it.

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      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
