Thread: Two Conversion Plates into 1 New one?

Hello All,

I have two Series 3 Long Wheel Base Land Rovers that had a 2.6 litre six cylinder Land Rover motor originally fitted to them.

One vehicle has a partially completed Nissan SD33 diesel engine and Nissan Cabstar gearbox/Land Rover transfer case fitted to it.

The other has a Holden 202 motor fitted to the Series 3 Land Rover gearbox arrangement fitted to it. The Land Rover gear box may need attention because it jumps out of top gear when the engine is going down hill or cruising along a flat = not under load.

Would it be possible to adapt one of the conversion plates so that it can be fitted in between the Holden 202 motor and the Nissan Cabstar gear box arrangement?

Would this just involve removing the Holden 202 front plate and removing the front plate that marries onto the Nissan SD 33? Then welding the two pieces together.

In this case would the most critical measurement be the length of the front shaft of the Nissan Cabstar gearbox? A distance that is already built into the current Nissan SD 33 to Nissan Cabstar gearbox conversion? Well I imagine that this is so

Otherwise, I suppose I could just track down a Holden 202 Nissan Cabstar gearbox conversion. However, I do like the idea of using what I have got on hand now. Hmmm anyone got a spare Holden 202 to Nissan Cabstar gearbox conversion they do not need any more - just covering my bases

Kind Regards
Lionel

You really do not want to have this sort of problem with your new setup. The alignment can be tested while installing the box.

Hello John,

You raise a very valid point. It is one that I have read about on the "Sticky Notes" section of the Holden Conversion pages.The one that goes something like "Read this Before you ..." I also have a dial gauge.

I am also working from the assumption that both conversions utilise existing manufacturer's bell housings and the conversion process does not involve a new bell house in itself.

When I have the time I will need to have a closer look at what I have got to work with. At the moment it is just a rough concept lurking within my "little grey cells".

Kind Regards
