hahahaha, thanks guys. was looking at a GTST with a 25/30 in it but i had a chat with my mates and would rather put 5k into a stock rb20. 240rwkw sound alright to me for a daily driver....

People often comment on the poor performance of the RB20, mostly its lack of torque. BUT, consider the R32 has less weight, shorter gearing also helps mask any lack of row rpm torque. Also the lack of stump pulling torque helps traction onto boost, where you can still make big hp through the mid range and up top.

LOL, though i am a scratched record...some copy and pastes from other posts...

And my parting comment will be have a look at this....

STD RB20 with a turbo and ECU upgrade

Compared to a std turbo RB26 with Poncams, and same dyno and same tuner

As you would expect the Rb26 spanks the RB20 down low, but in the rev range that you use at the track the RB20 punches well above its weight!!!!!!!!!!!!!!!

And...

Here is an R34 GTT on the same dyno, same tuner with Poncams and GCG high Flow, and then a very similar car out of NSW (though it had different tuner and dyno)

So, dont discount the performance of an intelligently modded RB20, all with std internals.

Sure there are better engines around, though for the money??? Well the only cars quicker then me at the track are 330-360rwkws well modified GTRs. My little std RB20 with a turbo upgrade manages to go quicker then all the SR20s and RB25s etc, some built, some with just turbos, even many of the lesser modified GTRs makign under 300kws. So if the RB20 was that far behind in performance then this would not be possible. Spend the money on getting some more poke out of the RB20 and what money you can on suspension, clutch and brakes to ensure that the all round performance of the car makes it a quick package :P

      Quieter performance exhausts (or muffler add-on options)

      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
