very nice

why change ecu tho? :P

Simple really - Rob the guys whos built the engine reckons the swop will give a noticeable difference because theres much more adjustment with the F con as its 32 bit not 16. This is also well supported by pretty much everyone Ive spoken to and Rob is acknowledged as one of the best mappers in the UK. .

So whilst it may not give much more power it should be much more driveable and more economical ( 99 octane aint cheap in the UK ) Also it will cope better with any future uprades should I lose the plot completely. :)

the other deciding factor is ££££

I have to pay for a full map anyway when its run in regardless - A full power FC map costs £300 an HKS one £500 (both from TR Racing) Ive been offered a HKS F con V Pro at a good price and can sell the power fc and the z32s for at least the same money .

Bearing in mind the costs Ive already on the engine at £100-£200 ish difference its a no brainer.

Took the car in to have the F Con Pro v fitted and mapped.

If only it was that simple.

First there was not enough current getting to the tomei fuel pump so it had to be rewired.

Then it was all systems go

First power run at ! bar gave 520 bhp :P Then boost upped to 1.3 and we got 490 ft lbs of tourque :yes:

Unfortunately one of the power steering hoses started leaking so no more could be done.

Still it looks like it will see over 600bhp which means the nismo clutch will need changing for an os twin plate as it wont cope with the launch control.

By the way anyone know if the power steering pipes are the same as a skyline.

Great car mate. Are you anywhere near a drag strip? Would love to know what times you can acheive.

BTW for a serious fuel supply solution have a look here: http://ripsltd.com/products.html

At last the mapping is completed.

We had to put a twin plate giken clutch in because the uprated single plate Nismo clutch simply surrendered.

The dyno readout was not working properly but Tweenie rob estimates 610-620 with just over 500ft lbs torque . This is based on him driving the car as well as the fcon readings and his experience with rb26s (which is considerable)

All I know is its bloody quick and bloody thirsty.

The wait and grief all seems worthwhile now.

Its my shade of green. But there the similarity ends.

Green with envy.

Very nice.

My shade of green too, but like Hugh's, the similarities end there with mine too. :banana:

Where is that rear wing from? I love it!

      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.
