Hello all.

New member here, joined up as I just purchased a neo engine for my RD28 Patrol. Maybe some people here will find it interesting/different!! I pick up the engine as of tomorrow, and I hope to get started Australia Day long weekend. Should be one hell of a battle, but I think it will transform the old battler into a real beast!!

So picked up the engine from a workshop in Sydney, picked it up for $1300. Not a bad deal I reckon. Strapped it to the work ute and transported it back to my workshop in Rutherford (45 minutes North West of Newcastle).

And here it is:

As you can see, she looks a bit sad and sorry, nothing a good extreme clean can't fix though.

It was also advertised as being complete minus ECU + loom. However, there was no intake manifold to be found, which peeved me a bit. Never mind.

I also got to take a home a crate full of the extras. Turbo, P/S pump, A/C compressor, alternator, various pipes and pulleys, bolts etc, its all there. Not being familiar with these engines myself, I took to the service manual to find out what I had, and what I still needed.

So I've tracked down an ECU and loom, an intake manifold, AFM, some new engine mounts (because one is cracked), an aftermarket intercooler and some piping to go with it (will fab up any other piping I need), a full gasket kit, auxiliary belts, and a timing belt/water pump/seals kit.

There is plenty of work ahead of me, that's for sure, but I cannot wait to get this all finished, and take on the sand dunes with this powerplant pushing the four wheels!! :D

hey mate i have a gu patrol im still converting to a neo 6 and i can give you a pretty detailed conversion process.as mine is near completely finished.

you use your factory rd28 engine mounts, find a intake manifold and engine harness with ECU out of a S2 r33 skyline (stuff i was never told!)

Why the S2 R33 ECU?

If this was my conversion, I wouldn't use a s2 r33 rb25det ecu... because you can't install a nistune board for future tuning. And yes, you will wan't to re-tune it.

I would use an rb20det loom and ecu with a nistune board.... or if you are going off road, a full wire in ecu. By the time you buy a loom/ecu/z32 AFM etc and nistune... you spent a few hundred more for an aftermarket ecu and loom- and you don't have to run an afm (thus less prone to failure if you suck up water/mud/dust etc).

Spend some money on a decent surge tank (for all the crazy angles you'll get) and have a look at water to air inter coolers.

Sounds awesome, put some picks of the truck up.

A workmate did that conversion to his. He loves it and it goes well! RB25DET neo and came with mines ecu.

Straight bolt into gbox etc, great conversion!!! He used a water to air intercooler setup though.

As mentioned above, use the RD28 eng mounts,

Use the RD sump too.

Also the RD flywheel and a heavy duty clutch. Heavy flywheel will help with heavy 4x4.

      Not R7R. Meant to type R&R, obviously enough.

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Bugger "making it look stock". I put one conventional internally fused Hella relay behind each globe. I just pulled the plugs off the back of the globes and built new loom segments with male and female plug parts to match up to the original loom and the globe, and used the original power wires to each globe coming from the switch through the original loom plug to trigger the relays. Ran a big fat (also separately fused) power wire across the front of the car to feed all the relays. It's as ugly as f**k, but it is wedged down between the headlight and battery on the RHS and the airbox and headlight on the LHS, and no-one ever looks in my engine bay, and on the odd occasion that they do I simply give no f**ks for what they think. Fully reversible - not that you'd ever want to. For f**k's sake. It's a Skyline. They made million of the bloody things. We've been crashing them into roadside furniture for 30 years now. There is a negative side effect to putting relays on the headlights. The coil current is too little to properly clean the contacts in the switches and they get blacked up and you have to open them up every couple of years and clean them manually. I have 25 years of experience on this point.

      R33 headlight relay conversion?

      By joshuaho96 · Posted

      I was poking through the R34 wiring diagrams vs R33 and noticed that the R34 has proper headlight relays while the R33 is like the R32 and sends full headlight power through the headlight switch. I'm not afraid of wiring but I really would like to do this in a way that looks OEM (clipping into open positions on the OEM relay box) and also unlike the factory wiring which interlocks the high beam and low beam on the halogen series 1 GTR headlights I want to make it such that turning on the high beams keeps the low beams on as well. Any advice on how to locate the specific connectors + crimp terminals + relays I need? I was thinking one NO relay for low beams and another for combined high + low running off the factory high beam headlight connector. I don't really want to splice into a crusty old probably discontinued factory harness so fully reversible is my goal here.

      Pretty sure they run the same engine as the Q50 hybrid which specifies 95 RON.  I ran 98 in mine for a while, but it made no difference in performance or economy, so I have been using 95 for the last few years.  I have never hit 6.0L/100km, but have returned mid to high 6 on the highway.  Being a hybrid, fuel economy is a lot more dependant on how you drive it.  At 110km/h, mine never goes into EV mode on the highway, so returns closer to 7.5L/100. urban driving can return low 8s if you are careful or over 10 if you are a bit more enthusiastic on the throttle.

      About a quarter of what you want to do. It's only R7R, not R&dismantle&replaceparts&reassemble&R. ? It is stock. I already told you, you will NOT have broken those. It's f**king 4th gear for Christ's sake. You just chipped the teeth off.
