Engine change or re-build ?

Post by Jersey Moke » Sat Dec 17, 2011 18:02

Hi

I have the opportunity to purchase a mini engine and gear box with low mileage, which has come out of a 1991 mini.

Can anyone tell me if I could do a straight swap of a 998cc Engine and Gear box from a 1991 mini, into my 1980 Aussie Moke which currently has a 998cc engine and gear box? Will the gear box ratios be the same and did the 1991 cars have electronic ignitions etc in them?

My other option is to strip down my current engine and gear box, which runs fine, burns a bit of oil, has a few oil leaks and jumps out of second and forth gear sometimes too.

Which option should I go with ?

Thanks

Nick

I think the starter moter would be different. Also, the clutch would probably be a verto type and the dizzy slightly different.
That said, it'd probably be less work to swap than rebuild (cheaper too)

You'd probably need to swap the diff crown wheel and pinion out of the the Moke into the new gearbox, I would expect the Mini to have a different ratio. Otherwise if they are both 998s it should be a very straightforward swap.

That said, it will affect the originality and might reduce the resale value, in comparison to reconditioning the original engine. When I transplanted my Moke, I kept the original power unit so that it can be put back to original later.

I'm pretty sure that they didn't have electronic ignition in 1991.

I think that a '91 engine would have a 65D dizzy on i. If so you'd be able to tell as there will be an amplifier module (a black box thing) on the side of the dizzy

Oh, and the cap will be held on with screws rather than clips

Oh that kind of electronic ignition. I was thinking about the SPI type with no distributor and a reluctor built into the flywheel.

Think that might be too big a job to put one of those engines in

Thanks guys I think that I will go down the re-build option. That way I know that everything will work correctly.

Its been done before. I think the idea is to get a "front cut" and transfer everything over.
