A Cometic MLS head-gasket is sandwiched in-between & now its time to finish it offIMG_9084.thumb.JPG.8e0ebcfedd0bbf22883fbd352678c50d.JPG

All assembled & ready to go - a cheeky ASR extended sump has also been given a new coat of paint & will hold 6.5ltrs of oil :)58e0ad20f346e_IMG_9088(noexif).thumb.jpg.3a50baaf2ea5787db0fb040d828ee0f4.jpg

Next steps are:
- Transfer the Alternator, P/S pump, Aircon compressor from the old rb20 & fit the shiny gtx3071.
- Remove the rb20 & gearbox and make space for the Neo and Rb25 gearbox which will be popping inside.
- Work out the wiring

Still so much to do....

If your willing to spend the dollars I would get this for the wiring side

Will do everything you need it to do, I also have all the wiring info somewhere on a hdd so let me know and ill pass it on

oooo ooo yummy, curious with your NEO what oil restrictors did you use? I've read the NEO block already has decent restrictors from factory and there's no need to run smaller.

Neo has single 1.3mm from memory (was like 3 years ago). I put single 1.2mm in my 25/30 Neo.

I read someone said 1.27mm which is pretty much 1.3mm.. I should be good then :)

Running OEM :)

No big news - been trawling through blurry wiring diagrams for the r32 to prepare for the massive job of wiring in the rb25 neo.
I have heard stories of people losing power-steering when doing such conversions and I tried to get to the bottom of this...

It looks like the HICAS ecu controls the electronic power-steering solenoid.
This solenoid is driven by Speed-input; at low-speed there is more power steering assistance & at high speed its reduced.

It looks like the HICAS ecu requires 3x inputs - Speed, Tachometer & Neutral.
As long as those 3x inputs are still supplied to the HICAS ecu, then there should be no issues with Power steering! (fingers-crossed)
Not sure where these 3 inputs splice under the dash or next to the ecu...will need to follow some wiring within the car & see where they lead..

Hope to create my hybrid r34/r32 engine-loom this weekend - some further reading is still required.

anymore updates on the hybrid loom?

Still working on it - have managed to map each wire on the Neo F3 plug as well as the r32 body plugs. Will attempt this weekend on the hybrid loom.

For those playing at home, found an easy method to repin the Neo F3 plug here -

    • That R31 was so cool. Only did Orange Park once. Scared the hell out of me.
    • Selling my TE37SLs since I've switched to smaller wheels.  They're for sale in Japan but it's pretty simple to send them overseas; USA excluded, since JPPost isn't sending there at the moment. Specs Front: 18x9.5j +22 5x114 Rear: 18x10j +20 5x114 Price: 320,000 JPY/ 3,285 AUD (current FX rate) Condition: a few scratches here and there, no bends, distortions or cracks.  Tires will not be included for international buyers, I'll get them dismounted before shipping. They're currently listed on yahoo auction and will be shipped in Japan with the tires if they sell here. Shipping costs to Aus: EMS (1-2 weeks): AUD 1,175 (current FX rate) Sea (2 months): AUD 460  (current FX rate)
    • The alloy coolant reservoir has a sight glass, so as long as I can see coolant in the sight glass it's GTG, as for PS, it isn't anything catastrophic if it gets low, and as it hasn't lost a drop since I have owned the car I cannot see it being an issue, even after putting the "big block" 2.5 in....LOL The only time it gets slightly messy is at oil changes, as the oil filter sits above the frame, and I need to use a plastic bottle with its bottom cut off to catch the flow when loosening the filter
    • Good on you for taking on the job, but it is a big one. Even if you have bolt on manifold and turbo, you will need: Post throttle pressure source to boost controller to wastegate (and FPR, and ECU/MAP sensor) Pre throttle pressure source to top of BOV(s) Oil feed - you can take that from the standard port in the middle of the block Oil return to block under the turbo - this is much trickier than it seems to route a decent/wide pipe past the manifold. You really can't use rubber hose because it is way too hot there, and also the oil out of the turbo core is a bit frothy so it needs to have a decent diameter Water feed - you can take that from the standard port in the rear of the block. Water return - mine runs to a T into the heater box return, just make sure you don't create a high point making bleeding hard. All of those lines should use 200 series style teflon braided hose with heat shielding because everything needs to be routed past the manifold. Also a turbo beanie is a really good idea to minimise the chance of the car catching fire (under bonnet lining in particular) You also need to decide a cam cover breathing solution as well, will you vent externally via a catch can (probably illegal) or return to the intake (plumbing required and can oil up everything over time) Keep in mind the intake and exhaust piping in the engine bay will be custom so you either need to be able to fab ally and steel or have someone you can get a car that isn't running to. Get the wideband fitting welded into the dump pipe at the same time. Also, just my opinion, a screamer pipe attracts attention and doesn't add power, I'd plumb it back if you want to be allowed to keep the car on the road. BTW do you know anything about how healthy the motor is, and what power you are targeting? Doubling or tripling the factory power on an unknown motor is a little risky. Also fuel system will need some attention (pumps, high current hanger, direct power and earth feed, injectors etc)
