I was going to do this on an A31 Cefiro but didnt. I did a bit of research etc and have an idea on what parts you need:

Box

Clutch

Master Cylinder

Tail shaft

Pedal box (I was told an R32 pedal box would fit in the ceffy so its likely to fit the C33)

Hand brake assembly (my ceffy has the old school foot brake)

Shouldnt have to change ECU etc as to my knowledge these run independent boxes.

I think thats about it from memory. Hope this helps

Yes the pedal box fits both A31 and C33, you also need a manual brake pedal (narrower), and manual footrest (also not as wide as the auto item)

Auto transmission is run on an independent ECU, which is located in the driver's side kick panel, the engine ECU will run fine without it. The only part you need to worry about there is rigging up the neutral-position sensor, or bridging the connector, to trick the car into starting, otherwise it will won't think it's in park/neutral and the starter circuit doesn't work.

So the box has its own ECU? is that then connected to the engine ECU or its just on its own?

Everything between Cefiro and Laurel is interchangeable except rear door cards, glass and fixed body panels.

They're the exact same chassis with a different shell on them.

Is that right? I didnt know that. Good news as I may be wrecking a ceffy soon (if it doesnt sell) and if parts fit on Laurel, well that means bigger potential market for me.

Does this apply to C33, C34 and C35 Laurels?

      Duncan's V37.......race car?

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
