Welcome to YW!

I'm so bummed that they didn't allow spectators last weekend, otherwise I would have been there! What class did you win? I've been dreaming of running my 2ZR swapped Vios in LeMons once I get a cage in it.

The C5X family (C50, C54, C56, C59) in the US will all (generally) bolt up to the 1NZ. For the ones with different starter locations you can swap the bellhousing onto whatever gearbox you want to use--that sometimes requires a bearing/bushing change on the pinion shaft.

I don't think any of the modern C5X gearboxes use an external oil cooler or even have a pump, so you'd have to get creative with that side of it.

The C54 isn't commonly available here, but I suspect that it only has different gear ratios and mounting bosses than the ones that are. I've got a thread with a comparison of the C50/56/59 around here somewhere...

I don't know that anyone has done a mechanical print of the bell housing and published it but I could do a paper transfer from one of my spares and snail mail it if you haven't found anything locally to cannibalize.

Most of the aftermarket support for the 1NZ is from Thailand or elsewhere in the Pacific, basically zero options here in the US. I think I've seen a thread about raising the rev limit in the OEM ECU but I don't recall what the secret sauce was to make it happen.
