Converting a 1275 Mini engine to fit a Minor

Anyone done this conversion ? Obviously the crank needs changing - and the front plate to take engine mounts, but what to do about sealing the rear main bearing ? Is it possible to do this conversion ?

To save time/effort and cost try the 1.3 Maestro unit instead

Thing is - i have several 1275 Mini engines in stock ! Does the Maestro engine go straight on to the Minor gearbox ? Or does the backplate need changing ? Does the Minor flywheel fit the crank ??

I *think* it's no to all questions, but I'm told Jonathon has done it before. Since I've got a 1275 Maestro motor, go on JLH, how did you manage it?
PS I know you will, but keep trade secrets under your hat ;)

No one done this conversion ? I need some ideas on what to do with the rear main bearing to seal it to the sump !!

No, as far as I am aware a mini engine has not been fitted into a Moggie, if you want info about the Maestro as Andrew says contact JLH.

There was the white H reg 1275 Turbo Minor. I think that engine was mini/metro transverse to begin with. Can't remember the chap's name now who did it, but he was a concours judge.

I have convertered a metro turbo engine to inline (in my last minor)
you need an ital crank and and the rear bearing cap. ( plus the front plate and a suitable rear plate depending on what yearbox you are using.
Only enginerring needed is to have the mainbearing caps linebored to ensure they er... all line up!

Ah but he only went to £16:00 you were £60:00 above that, but I know what you mean.

I wasn't watching to closely - put in a 'bid up to' of £76 something or other, and carefully left ebay to it , 'cos I'm terrible at resisting temptation

PS bmcecosse, if you want a nasty old Maestro engine sans head, you're welcome to mine - and I'll be driving up to Glasgow in the not to distant...

Yes - it was an expensive crank !! I was only chancing my arm with it - can't get to ebay during the day - just as well - spend a fortune ! In future - don't feel guilty about bidding - it's an open auction. How nasty is the Maestro engine? I live just south of Glasgow.
Turbo - thanks for the tips - but line boring the mains !! I was hoping for some kind of fix to seal the sump onto the existing rear main cap.

The engine's been sat in the garden with no head on it for a few months, so not in a good state - the Maestro it came from was scrapped 'cos the engine was going (don't know more than that), but if it's any use... Where are you? Kilmarnock?

I've seen an engine out of a Morris 1300 fwd which was line bored and put in a minor van and apparently it was a much better performer than the marina. Apparently not too hard to do but the marina is easier obviously.

Sat in the garden with no head on doesn't sound too encouraging !! I'm in Stonehouse - just at junction 9 M74 - the one with the A71 going west towards Kilmarnock.

Aha - can't say I know Stonehouse well, but have driven past it a million times on way from Glasgow to Galloway. No, the block's just been sat out in the wet since I took the head off, and 2ndchance@ebay have just emailed to say that the sale of that crank fell through, and would I like it. It appeared to be legit, so I took it - hope it isn't a con, I'll hang on to the block anyway in case...

It's amazing how many sales 'fall through' on ebay - how do they get away with it ? I guess they just re-register with a new name !
