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.

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!

What compression pistons?

 

Specifications
Part Number: SC7297, 14028-6
Make: Nissan
Engine(s): RB25DET NEO
Year(s): 1998-2002
Piston Material: 2618 Aluminum
Bore Size: 86.50mm
Compression Ratio: 9.0:1 CR
Connecting Rod Material: 4340 Forged Steel
Connecting Rod Length: 121.50mm
Compression Height: 1.220"

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

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
