hey everybody starting a ke70 4age+t build...

couple of things do you need to swap ke70 xmember with a ae71 xmember and i have a 3rib 4a block with the 8flywheel hole crank and from info it has smaller conrod bearings wondering if the main bearings are the same if they are

is it possible to fit the bigger crank in.

 

cheers

yes to both your questions.

you'll need to change the x member over so you'll have the correct mounts.

The cranks have the same size mains so you can change it as well.

 

And just for your info, :) try using the search function next time, most questions have been asked before.
