eta crank on a b23 block

[The Humjet]

I have a eta crank lying around in my garage and I was wandering if I use that on my b23 block what result would I get?
Just a question to throw out there since I was going to rebuild the bottom end with new bearings and piston rings.

you will get 2443cc, not worth it IMO.

i mean, you will still need to change your pistons, or work the ones you have so they dont stick out of the block too much.

a friend bored the block to 82mm, plus the m52b28 crank, that gives you 2661cc, you still need new custom pistons. but this way you could go for a 135mm conrod (with the new pistons you can have the pin higher to compensate the 135mm conrod and the 84mm crank).

with a decent head, either 731 or 885 (or a SERIOUSLY modded 200) you should have a nice running engine.

all this, is considering that changing the block for a 325i/325e one is not easy/cheap down there.

thanks man since I posted the question I managed to get my hands on an eta block, now with the 731 head like you said it should be a pretty good combo
