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?

      That's probably OK. That's a face to face compression joint between two surfaces with the clamping load provided by those bolts. So.... it's unlikely that the bolts will end up feeling that load in shear, unless the clamping surfaces are not large enough, bolts not got enough tension on them, etc etc to prevent the two faces from moving wrt each other. Which... I would hope the designers have considered, seeing as it's probably one of the most important things the upright has to do apart from resist collapsing in its own right. But yes, it would definitely be worth asking them what their safety factor on that part of the design was. I tend to think that the casting, being a casting, is not necessarily the strongest bit of material in the world. It's about an inch square, and when you think about the loads that are being put into it, you have to wonder what safety factor the Nissan boys (and every other OEM engineer who has designed all the millions of other uprights that look essentially the same) used to account for defective casting, aging, severe impacts on the wheel, etc etc.

      Those bolts would be orders of magnitude stronger that cast aluminium though.  And its mainly clamping force, not shear they are dealing with?

      Except all that twisting force that is breaking a cast piece, appears to be going through 4 bolts in the picture Johnny posted of the BryPar one...

      R34 auto to manual conversion help

      By GTSBoy · Posted

      The smart approach is to use the gearbox loom from the manual car. Makes it a lot easier - just plugs into the switches on the box and plugs into the main loom up near the fusebox. Then you only need to deal with bypassing the inhibit switch. The other approach requires you to use the wiring diagram to identify those wires by colour and location, perhaps even indulging in a little multimeter action to trace them end to end to make sure, and then.... you will have the answers you need. The R34 wiring diagram is available on-line (no, I do not have a link to it myself - I would have to do a search if I wasn't able to go to the copy I have at home).
