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.

really thats a sore i can relax on the manual interior parts now and just have to sort tail shaft and crossmember out ive read that crossmember 'B' is the one to use and have checked my mates crossmember on his factory manual c33 and it is a B but will it fix with the 25 box thats the question fingers crossed as we both are about to take on the same things

Does this apply to C33, C34 and C35 Laurels?

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      R33 GTR running -9 with no tune

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
