Depends what power you want really, I've had two RB26 set ups essentially and the one I have in my GTR now is the best I've had (the stock unopened motor is holding it back alot however) I have had 3 single turbo set ups on my GTR to date.

I'm currently running a Precision Billet series PT6262 turbo charger, un real response full 1.6 bar by 4200rpm on 98RON however with a built motor my peak power would be a lot better. Previous set ups have included a Garrett GT3582R and a Turbonetics T66 (plain bearing 0.90 roughly housing) I've never liked the poswer delivery of twins however they may have their advantages in the 3-360kw range. However I have no complaints since changing to a single high mount plus the maintenance is a hell of a lot easier :)

Awesome thanks mate :) is it a lot of stuffing around to go to single? Sounds like you have some awesome setups!!

What do you have to change to go single? Do you still get aircon ect. I was reading that some people change a heap of stuff I'm not gonna go to big just something that looks nice and is resposive

if your arfter a bit more kick, why not just get some -5's? you have good supporting modes in place and they will just bolt up to your current setup. would be a cheaper option then going single.

single would require new intake piping, exhaust manifold, dumps and front pipe etc.

If your keen on the single route, i see alot of people getting good results with a t04z

Well it made 320kw on around 20psi which I'm

Not happy with however it may have something to do with the only mildly decent tuner up this way tuned it to around 10.8:1 afr's lol so it would make 350 or so leaned up a bit... However I was also after a bit of life from the stock motor to so I'm not complaining.

Going to a single was the best thing I ever did for my GTR, in terms of changing things that's par for te course however it's definitely worth it.

My GTR is currently getting parted out.... So my turbo set up is for sale complete with hot side piping, dump and front pipe to suit 32/33 GTR and intake pipe lol

Sedat i have been very impressed with precision turbo's. I hve just finished a r34 neo with 5558(precision) it made 367kw on 22psi ethanol and full boost at 3900,

I have just fitted a 6262 twin scroll onto my personal GTR which i was planning to tune this week but found a water leak under the plenum so i pulled that iff tonight.

My aim is 400kw with full boost at 4200.

U should go a 65 series or so for 450+kw

      Quieter performance exhausts (or muffler add-on options)

      By Murray_Calavera · Posted

      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
