Rekin Posted June 19, 2017 Author Share Posted June 19, 2017 Injector loom modified, injectors fitted, splitfire coilpacks fitted & engine loom wiring in progress... 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! 1 Link to comment https://www.sau.com.au/forums/topic/467808-r32-gtst-rb25-neo-rebuild/page/3/#findComment-7835852 Share on other sites More sharing options...

DaymoR32 Posted June 22, 2017 Share Posted June 22, 2017 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? 1 Link to comment https://www.sau.com.au/forums/topic/467808-r32-gtst-rb25-neo-rebuild/page/3/#findComment-7836404 Share on other sites More sharing options...
iruvyouskyrine Posted June 22, 2017 Share Posted June 22, 2017 Wiring Neo in is pretty simple, not much different to normal 25. Let me know if you need any info@rekin and I'll be happy to help. I put a neo in my R32 2 Link to comment https://www.sau.com.au/forums/topic/467808-r32-gtst-rb25-neo-rebuild/page/3/#findComment-7836417 Share on other sites More sharing options...

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. 1 Link to comment https://www.sau.com.au/forums/topic/467808-r32-gtst-rb25-neo-rebuild/page/3/#findComment-7836508 Share on other sites More sharing options...
Rekin Posted July 2, 2017 Author Share Posted July 2, 2017 Working on all the little-bits to make the car go... Time to flex! Nothing beats new parts...replacing the coolant lines. New clutch slave cylinder with custom hose 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 suit Hopefully next week we will be in a stage to fire-up and see if my wiring has been done right! 5 Link to comment https://www.sau.com.au/forums/topic/467808-r32-gtst-rb25-neo-rebuild/page/3/#findComment-7838117 Share on other sites More sharing options...

Rekin Posted July 22, 2017 Author Share Posted July 22, 2017 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 4 Link to comment https://www.sau.com.au/forums/topic/467808-r32-gtst-rb25-neo-rebuild/page/3/#findComment-7841097 Share on other sites More sharing options...
Rekin Posted August 5, 2017 Author Share Posted August 5, 2017 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 6 Link to comment https://www.sau.com.au/forums/topic/467808-r32-gtst-rb25-neo-rebuild/page/3/#findComment-7843087 Share on other sites More sharing options...
