R32 GTST rb25 neo rebuild


Recommended Posts

Injector loom modified, injectors fitted, splitfire coilpacks fitted & engine loom wiring in progress...5947b1ec03160_enginewiring.thumb.jpg.f8cefb44982d82e0f6b0358dd8aa012e.jpg

 

Ditched the thermofans as they weren't really keeping temperatures under control, back to engine fan but a bit too close for my liking...

Have purchased GKTech engine fan which supposedly is thinner & more efficient (win-win) - on its way....

Dummy-fit the top intake manifold & Neo engine cover to see how it will all look. So far so good! Couple of hoses on their way from Japan to finish the intake plumbing...

Hopefully finish-off the wiring by next weekend & get the car ready for some intercooler, intake pipe & dump/front exhaust fabrication!

Loving the progress, making me lean more and more to doing a neo rather than a standard RB25! you had any real difficulties with the wiring so far? or has it all been pretty straight forward?

Wiring still in progress but a lot trickier than a s1 rb25 motor.

The neo loom has so many plugs for TCS, ABS, Sensors, Headlights, etc so its been slow progress to work out which to keep & which to cut.
So far, Ive worked out that the rb20 ecu grabs ignition voltage near the plug at the airbox and its a matter of wiring this to the brown eccs/ign relay & another pin on the ECU.
Im trying to make sure aircon, power steering, hicas, wipers & all dash switches/sensors work with the Neo so am tracing each wire to each plug and working through it slowly.

The Knock subloom on the r32 is separate and connects into the rb20 engine loom; whereas the Neo knock loom is integrated into the Alternator subloom; still working out best way to connect into the Neo loom.

Working on all the little-bits to make the car go...

Time to flex!

Nothing beats new parts...replacing the coolant lines.

Tailshaft shortened, balanced & fitted.

Replaced the 30mm Turbo spacer with a 20mm spacer, much  better fitment now, hopefully the dump/front clear the aircon lines now...

With a 7ltr ASR extended sump, means more oil - bought enough for two changes & gearbox oil to suitoils.thumb.jpg.6e066d3e750d15669343cb30b8c2ae10.jpg

 

Hopefully next week we will be in a stage to fire-up and see if my wiring has been done right!

Wiring loom finally sorted and Nistune + flex board soldered in.
Despite AFM plugged in, larger injectors on a stock map and no intake pipe connected, the engine cranked & started!

Car will be towed to fabricator and tuner on Monday, hopefully have a running car this Friday if all goes to plan :)

Some fantastic work done by Havoc Fabrication, their attention to detail, care and professionalism is above all else. Thanks to their workshop for tackling this mammoth of a job.

  • Custom stainless steel intercooler piping with zero holes cut
  • Custom stainless steel intake pipe from z32 airbox
  • Custom stainless steel dump & front pipe with another cheeky o2 bung for wideband sensor/tuning

A couple of wiring gremlins to sort out last minute but the car is ready for run-in tuning this Monday :D

    • Once the airbag is off, to remove the steering wheel.... Undo the 2 plugs into the clock spring, and the horn connector from it's clip. Hit the 19mm nut with a rattle gun (preferably) or if you don't' have one, you probably want an assistant to hold the wheel in place while you use a breaker bar to undo the nut Then, screw the nut back on 3 turns, and pull the wheel sharply towards you. If that doesn't work hit it medium force with a rubber mallet on either side, or possible behind if you can get there. If that all fails (it shouldn't!) you might need a steering wheel puller
    • So, to next task....the carbon fibre steering wheel was either an expensive factory option or a chinesium special. Either way, I don't like either the flat bottom or thick ring style, so it had to go So...to remove the steering wheel.... First, disconnect battery negative and stop on the brake pedal for a few seconds. Then, remove the small circular covers on each side of the wheel's rear surround to uncover the airbag clips. You need to push something like a flat bladed screw driver through, you need to push the steel clip inwards and pull the side of the airbag forward. Once you've done the easy side, same on the centre console side. You can see the tab you are shooting for circled in red Then, disconnect the horn spade connector and for the yellow airbag plug you need to get something small under the black locking tab to pop it out, then the connector releases......airbag is off  
    • @99RS4just wondering if you ever took photos of the footwell lighting / how you bypassed the controller, im keen to haver footwell lighting come on when I open the doors too   
    • Ultimately, if the tip is not far into the runner and the o-ring seals, then you are in business. Have you applied pressure to it as is? It is not really a problem for the injector to twist once it is bolted down, the oring seals it and you don't want it jambed into the oring too hard The plenum is intended to take multiple size lower injectors with different adapters, but the way you have it is fine if they seal.
    • Are these the Dmax ones you are in reference too? https://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35#description Not a bad idea to get the uni flange ones. I have sent just jap an email too. Will see what they say lmao. Only thing is the Dmax ones are on a big back order. Low key anything will be better then my OEM ones I got as they are sounding like popcorn when I go under load lmao 😂☠️🪦.
