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.

    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
    • I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things
    • I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt 
    • So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm. 
    • Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
