View Full Version : M20B23 crank question

03-06-2007, 12:10 AM
hi ppl, i have a question regarding the M20B23 block and compatible cranks.

down here there are no Eta blocks, and really few M20B25 blocks, so swapping the bottom end is not an option.

since boring the M20B23 is not an option either, due to water passages. the only way to increase displacement would be stroking.

is there any way to fit into a M20B23 an eta crank? or even a S52 crank? even if heavy modifications are required, is this posible somehow?

thanks for any info you can provide on the topic :)

Well we didn't get any of these in the US (aside from gray market). so i would say the best place to ask this question is www.e30zone.co.uk they know all there is to know about that motor. good luck.
