I didn't respond immediately, in the hope that someone actually knew a god answer, but seeing as no-one has responded yet....

I wouldn't hold out too much hope of there being a "kit" to rebuild one of these. Whether you can even get everything you need to fully rebuild one might even be hard to answer. I'm sure that you can likely get calves and rods and pistons and rings and bearings and the like. But sneaky little minor parts might be harder to track down.

Gawd. I just saw the typos in my post and nearly had a seizure, until I realised that calves is easy to mistype from valves.

Engine swap options are obvious. VQ35s of various sorts from later V cars and Z cars, and the same with VQ37. With or without turbo, depending on your willingness to go down that rabbit hole.

Honda K? Arguably a better motor, just sounds like shit.

Most parts would be available through suppliers like partsouq, amayama, nengun, Nissan themselves. Doubt you'll find a rebuild kit as such. There are some parts that are shared with other Nissan engine families. Things like bearings, valves, valve guides etc.

Partsouq/amayama will be your friend when it comes to part numbers and price.

Depends what needs to be done.
I'd personally go with VQ35 crank, cams and forged rods into a VQ25det, making it effectively a 2.8L with 8.8 compression.

There are no VQ25det "kits" that I am aware of although there is a mob (Takumi Autoworks) in the UK which are putting a kit together.

      GOT SUM's RB34

      This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O

      Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though.

      215/45/18 tyres are probably a little on the low side compared to the factory tyre, it should be closer to a 245/45/19, which will get you about an extra 11mm of height, and should make you speedo read a bit closer to reality. 245/45/19s will be a bit too far the other way and you risk a speeding ticket as your speedo might read slower than your actual speed.  245/40/19s would be correct if you are going to 19in rims, they will give you a similar total diameter to the 245/45/18 tyres.

      That's something I forgot to put in my list. The aggressive anti-squat in R32 is a f**king menace. I still need to decide if I'm going to drag the subframe out of my car and weld in the GKTech corrector kit. The main reason to dither is the need to switch to spherical joints in the lower arm to account for the twist induced in the rear pivot caused by lowering the front pivot. And yes...we do put better subframes in R32s, and I wish I'd gotten an S14 one instead of an A31 when I did the "take off and nuke it from orbit" HICAS delete all those years ago.
