I recently bought a 1980 mini, having an engine swapped mg metro 1275 engine bored out to a 1301. I wanted to put a turbo kit on it, but wasn’t sure if this would put too much much strain on the engine block and crack it, as it has already been bored out.

That doesn’t really make sense, you can’t take a 998 to 1.3, are you sure it’s not just been replaced by a 1275 lump? I suppose you can get kinda close with a 1098 crank and +100 bore?

That takes you to just about 1200cc.

What’s 100cc between friends?

I have just looked, and it has been replaced by a 1275. Lucky find. I did the dvla check and it said it was a 998, so must have been swapped at some point.

Most turbo conversions will be rebored just to fit new pistons & recondition it in prep for the extra power.

 

Anything up to 1330 can just be considered reconditioning. Going any bigger for a turbo doesn't make a huge amount of sense as you produce more power than you can sensibly use with boost & larger displacement makes it harder to keep the compression ratio down.
