Is it usable with a rb25 neo?

Well.... maybe. What TCU is there? Keep in mind that a NEO ECU either expects to also be the TCU (when it's out of a GT-T) or it expects to talk to a separate TCU. There are specific bits of information that go backwards and forwards between these boxes, and it is almost certain that a Z32 TCU won't speak the right dialect.

If you were using an aftermarket ECU with the Neo, it would probably be a lot easier. And in fact, these days people like Haltech are rolling transmission control into their ECU's capabilities because of just these problems.

It would also be possible to go a standalone aftermarket TCU, although that might be difficult to integrate properly with a factory Neo ECU, for the same reasons again.

If it is in an R31, and behind an RB, then someone has probably put it together, because the VG bellhousing is not the same as the RB bellhousing, even if there are usually similar gearboxen hanging off the back of them.

Google search of 51x00 shows up many parts that refer to Z32, but that may or may not mean anything. The number also shows up some Maxima parts (which were also VG, but FWD) and so it is possible that it pertains to a whole slew of Nissan trannies.

Google of model number shows 300zx

Post up what the entire tag says. Is JATCO mentioned. If its a RE4RO3A, I have one in a R33, bolted to a RB 30/25 with neo head and cold side. It physically fits with modified converter, tailshaft and rear mount. The RE4R01A bellhousing for Skyline bolts straight on.  Never got the box to play nice with the Nistune R32 ecu and matching TCU  so went manual valve body to make it work. Are you confusing big shift kit with manual valve body.

    • Have you put an aftermarket oil pressure gauge on and verified your oil pressure?   Noise being on the block, on exhaust side, how high up the block does it seem to be? It could be the VCT system getting cranky, especially if it's mainly at idle, and when warm, as that'll be your lowest point for oil pressure. Could be showing that oil passages / VCT solenoid are blocking.
    • Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!
    • Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers  
    • This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?
