These results give me a little tingly feeling in my balls thinking what the -5's will be like on my 30/26. Obviously provided it's setup as brilliantly well as yours is.

Hats off to you for your perseverance with it! Now the fun begins (driving it!).

Enjoy!

Car is finally booked into Insight on the 19th of April for the ECU, fuel system and sensor wire in plus the tune. Thats the good news. The bad news is that V-cam aint gonna fit with my pistons and ho

Small update.... ITS RUNNING. Fired first go! Smells like burnt dust apparently .

A 9174 would just make the EGP pressure issue worse and in my mind it seems like a bit of a GT RS shit going on. Not that it's horrendously bad (It wouldn't be no twin buttplug pressures), That's NOT

I think you need a 4wd dyno to do the final power output.

Do you know how much timing your running?? not sure if you know, when running tight squish you dont need the timing and if you put timing in it does not like it and what AFR is the tune to under full load?

I can't answer that Bobby. I will find out specifics later on as the tune is not finished. it only had 9 runs or so. I dare say the AFR's will be a little richer then what you like ;)

As for 4WD dyno. Wanna spot me a run up on yours? :P

Was lucky enough to take a mates 26/30 for a belt in Melbourne with dash 5's built by rp

300rwkw at 3000rpm

You will love it

A fair bit of thought went into it all. I think the interesting thing is the cam duration. They are not massive lumpy grumpy things!

Having seen a sorted 30 with 5's on the same dyno.... providing it's sorted, you're in for something special ;)

What is the deficit going from rwkw to awkw in your experience Bobby?

300rwkw at 1400rpm less than Paul's is insane!!!

Didn't your mate Deimar do a test at CRD one day and there was 2 KW in it?

that member repetition looks to be a virus - i saw the same thing a few pages back.

were your cams dialed in?

Zero zero... We only did 9 runs from a totally new ECU and that's what it spat out.

They will have a tickle this week to see what it does. If it takes away from the midrange I don't want it!

I mean when the motor was build! since the cams are custom, its why i asked if cams have been dialed in to find zero? if not, i think its a good idea to know where the cams should be before playing with them

We know where they are at zero zero. Yavuz set the loves up where he thinks they should be.... Not to say a degree here or there might make the difference.

Lets see what next week brings ;)

Geeeez looks like that port work on the head is doing the trick...

Who would have thought HKS knew what they were doing :/

But did they? its had the super special cams and springs changed in....

Edit: of course they know, but is it better than something that could of been done locally, as yavuz deemed it necessary to make these changes

Its hard to quantify any gains from port work without doing back to back tests. You really need to do a stock head with all the same bolt ons. Then try a worked head with all the same bits and compare results. However, not many people actually have the time or money to try that exactly.

Everyone gets tempted by changes when they have the engine apart lol.

Well nothing changed apart from the head, cams and an extra 0.5mm on the pistons. ECU did but meh

      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.
