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.

    • Ok guys thank you very much. GCG highflow it is then 🙂 
    • forgot to mention that when it does this it does not kill the engine, but I have not kept the pedal down long enough to let it, as I see no reason to beat up on it as its got to be something simple, small and dumb causing this.  And as soon as I let off pedal, the engine returns to its normal super smooth operation and rpms re-stabilize quickly, once below 4k. 
    • neither stumble or cut really seem to be an appropriate term....hard to explain its like a rev limiter but at 4k, but it violently shakes engine and entire vehicle as the rpms will not rise over 4k, even with slow acceleration. as soon as it hits 4k, it sounds like entire spark is lost entirely. plugs were 1.1 which I used as such, but later put in new plugs gapped down to .8 changed back after issue arose when I replaced the coils, still does it with either plug gap...damn and it was all running so good.
    • Oh how times have changed! I actually lean it out relative to my water/methanol injector duty cycle. The methanol adds a lot of fueling and you can then lean it out even more due to reduced knock. 
    • Yeah my thoughts are the same, a well thought out WMI setup, would be slightly ahead of just straight E85 and you're also chemically intercooling the charged air, dropping it even further. This is why you need to add so much more fuel as soon as you spray. I remember someone taking me through their set up before (Dennis, has a R33, lives around Cabramatta - no idea if he's still around on this forum). He would target AFR 10:1 on 98, then as WMI ramped on, AFR would lean back up to 11:1. Amazingly, he did this all through his PowerFC, a relay to cut power to his EBC solenoid if there was not enough line pressure on his WMI kit. And of course, if there wasn't any boost made above gate pressure, you wouldn't be accessing the load cells with heaps of timing for WMI. One downside to that rudimentary setup, once the WMI came on, the EBC would unleash the dragon, and of course all the timing. Tyres would fry lol.
