1275 fuel injected mini engine in a sprite?

I have access to low a km, 1997 mini - fuel injected and I wonder how compatible this engine is in a sprite? Would this be a relatively simple transplant? Can all the related components just be swapped, and the engine bolted right on? I didn't come up with anything on a search - so I'm looking for a little knowledge. I suspect it's not as simple as I think - thanks!

You're right, it's not. The crank is completely different (no flywheel flange) , and of course the Mini has the integral gearbox in the sump. You would need different rear main cap and related things like the oil pan, flywheel etc. There are some differences in the block, but I don't remember specifics any more, but there's more to do than swap a few simple parts. You could probably swap the injection and head though.
 
And the advantage in trying to make this one work.
65bhp @ 6000rpm 72lb ft @ 3000rpm 1966-74: MG Midget MkIII
1966-70: Austin-Healey Sprite MkIV
1971: Austin Sprite
 
63bhp @ 5500rpm 70lb ft @ 3000rpm 1997-2000: Mini Cooper 1.3i (TPi)

Less Power and a whole lot of issues to adapt. Even moving head and FI gets you less HP and torque. Back to the drawing board.
 
Thanks for the speedy replies - and as I suspected, wishful thinking. It's just that the Japanese minis are so cheap, seemed like a potentially great way to source a newish donor car.

It's hard to resist the low prices of the minis at the Japanese auctions, but I'm still dreaming of the day I will be driving a sprite again.
 
You may be able to use the head and injection system from an SPI. The MPI will require more work. Both engines handle sensors and coolant flow a bit different but I cannot advise you of the details. Keep in mind that if you have problems with the ECU or injection components there are few people/shops versed in the U.S.

If you were looking for a way to get more power, the head and blower from a Metro turbo might be easier to implement on a Spridget.
 
Any gain in fuel economy?? May make the swap more appealing. I know computer controlled FI has done wonderous things to modern cars.
