The 6262 sillyness is never ending... New cams just got the most power and torque it's ever made

Dale is 100% correct its a well proven fact that smaller cams in RB's aid in response. Even going from a stock cam to a type b pon cam will cost you response. Been many track guys that have thrown the

Left it for now. Was up too 262kw at 5500rpm 14.5psi. Was just having a play tonight and good to hear it running.

Waiting on the new fuel system to arrive so we're ready for the eflex.

Surge tank and lines are on the way after ur very helpful input Matt. Cheers for letting us know about urs.

Fark im so keen to get mine on the dyno now.

Looks very similar to GT2871 results on a neo 25, I have a turbo that is highflowed with the same wheels that looks very similar to that graph though less power due to the restrictive rear housing.

Be interesting to see how well this turbo performs when you finish the tune! Neos always seem to give fantastic results.

Yeah.... Nah! It doesn't haha

Neo usually make a little less power actually because they are pingers

The few tuners I talked to seemed to think they always made more power as they seem to rev more, seen two results that seem to point that way, eg matt from nistunes r34 that makes 310rwkw on a 0.63 gt3071r with poncams on only 18psi, dyno sheet is on here from a reputable dyno/tuner, and then mine which is a highflowed rb20 turbo with the rb20 rear housing still that makes ~258kw on only 16psi

On the same dyno for both?

Regardless from what i have seen, neo's seem to get a bit more compared to regular rb25det's with similar bolt ons.

Yep both on same dyno same tuner. Pete from nistune and the morpowa dyno in adelaide, he told me every neo he has done has gotten fantastic results compared to the r33 engine, "chalk and cheese" were his words from tuning multiple neo and r33 motors.

I also had identical everything just changed from r33 rb25det to a neo rb25det with the r33 intake, all the same sensors, hoses, literally everything the same just the block changed and went from ~236kw at 18psi to 258kw at 16psi.

That's a solid improvement!

Is there any rewiring for sensors or the loom etc needed to put a neo rb25 in instead of an s2 33 rb25 or does just the ecu need to be changed?

The 34 looks like it will put up a good number, I think you'll shite 400kws in Jez

Im curious to see when this turbo maxes out.

I know Kurtis is now a power junkie but this thing is aimed at max response with strong top end. I have the goal set at 350+.

Time will tell with my one too. Its a 700hp turbo. But same again its main goal was response and 380+

He'll make it, i have faith! Its a 700hp turbo vs my 550hp turbo and i NEARLY made it, so you guys will make it for sure :D Cant wait to see, its sounding good!!!

      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

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
