managed to post in the tutorial section, sorry.

Ive just got a R32 Gts, and it has been modified with a RB25DET engine and gearbox, most of the engine part is mounted and working, the part where im at now is the wiring part, have come so far that i got the Ecu harness threw the firewall and that, now im wondering what i need to connect to the loom inside the car, its for the intstument panel i guess, ive got a wiring diagram for the RB25DET tho half of it is in japanese... so having trouble sorting the parts out, anyone done this and can give me some help or tip on the way?

That might help... basically I used an RB20 ECU diagram.. worked out which wires came out of the RB20 to the body loom.. marked them with tape.

Then when I got the RB25 wiring, I looked for the same wires coming out of the rb25 ecu, and connected them up to the corresponding r32 body loom wires.

Using that method I got through the whole conversion in a few days of mucking about. A professional would have done it much quicker, but it cost me nothing.

thanks mate, ill start with that, problem is that the harness from the RB20 engine was taken out before i got the car, gonna dig in the boxes i got with the car and see what i can find, else i probably need to follow the wires from the instrument panel.

is there a good diagram of the RB20 Ecu also? i searched but only found for the RB26

moving forward, managed to find the fuel pump relay controll cables, who when i try to start the car i just here the click from the controll box, tracked down the cables thats coming from the fuel pump controll box, and they comes up to one connector att the passenger side, but i cant tell where they should be connected, and in the R32 service manual there seems to be some wire diagrams missing, like from that connector and forward :D

      Front tower strut brace options

      By iamhe77 · Posted

      Anything for a 2003-2005 G35 will fit an M35. Just be mindful about clearance if you're running a plenum spacer or runner spacer.

      You know how I know I'm getting old? Because I feel this quote jells with me and SAU Forums, ha ha ha. I've gotten lost a few times as I had muscle memory to scroll to where I wanted on my phone and just click, now I'm lost... Ha ha ha     "I used to be with ‘it’, but then they changed what ‘it’ was. Now what I’m with isn’t ‘it’ anymore and what’s ‘it’ seems weird and scary."

      Rb25 into r31/wont idle

      By MBS206 · Posted

      You don't lose spark if your battery isolator isn't wired correctly and the ECU still has power from the alternator.   Car has an epic wiring problem. Sounds like power connected really really badly in places. Possibly a power pin on a ground pin for the ECU, and constant power in locations that should be switched ignition.   It needs someone good at diagnosing electrical, a good multimeter, and someone with the wiring diagrams to match the engine loom that has been put into the car, and wiring diagrams for the body side of things from the car.

      Front tower strut brace options

      By PNM35 · Posted

      Hi folks, what options exist for PNM35 or what models share the same dimensions and fitment for the front top of tower strut brace. I have seen a few options pop up through Google, the Ultra Racing Australia for one. I have seen some eBay ones that claim they fit C34 and M35 but can't find details if to work out if its true. Also found Taiko / TEMA4x4 claim the one type fits: - Nissan Stagea (2-nd gen; M35) 2001 - 2007, - Nissan Skyline (V35, HV35, NV35, V35, PV35) 2001 - 2007 - Infiniti G35, G35X (3-rd gen; V35) 2002 - 2006 But not sure how true that is. Anyone fitted one or know of someone using one and can confirm what does fit?

      AC Compressor

      By Butters · Posted

      I got the full kit.   The compressor as above is much smaller and lighter.  Also quieter. Bracket is visually mint and much lighter. The dryer and heat exchanger(rad) are one unit. Also smaller and lighter.  Much more room for an oil cooler. The fan I got was a bit Meh and I might change it.   And above all else it is more efficient, tested a good 3-4 degree's cooler than the old system, which is a lot. Disclaimer though - It wasn't a back to back test given different days. It really does feel colder though(always).  And this example is in my car with that crusty looking old compressor, not new vs new
