Hi, will soon be upgrading to a r34gtt stock mount. I was wondering if there are any modifications to make it fit, or is it a strait fit?

And to get to the r33 stock mount, can it be done by removing the wheel guard, or does the front bar have to come off?

And with the r34gtt cooler on the r33, is there a notible difference while running a bit more boost, such as 10psi?

will appreciate any helpful replies

Thanks,

I installed R34 Cooler on mine,

with the front bar off very easy to do,

since the front bar on have 4 bolts holding it, very easy taking it off.

its really a bolt on job.

performance wise, no idea, only when u increase boost!

Straight bolt up. No mods required.

Make sure you have the r34 duct too. To install the duct, the front bar has to come off. This requires a trim to get the bar back on. You'll know what I mean.

No noticeable increase in power.

What is a duct?

Can i use r33 duct?

Must be some air duct to run from the stock hole in the bar to the cooler.

When I put my R34 cooler in, the bottom of it sat much lower than the stock R33 one. So much so that it's pushing the lower shroud down and creating another airduct under the bar!

I don't know how much difference that would make, but to theorise on your other question about performance, the R34 cooler has bigger in and out pipes on it, and the core is thicker. In theory I beleive this means you could push more flow through it. Dunno if 10psi makes any difference, i'm still running 7.

Considering the R34GTT's are 206kw stock, i'd say that this cooler would be good for at least that. I'd also guess that your intake temps might be *slightly* lower under load due to the increased surface area of the taller and thicker core.

I'm going to mount a JayCar temp probe in my intake somewhere and monitor the temps. If it all seems good, then i'll run it up to 10psi.

      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

      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.
