can i use the crank,rods,bearings and pistons from a d16a1 in a d15a3? ive been told that the pistons will fit with 75mm overbore but will the other parts work without sever mod? for those who want to know im building a 1st gen crx and doing the "hydra" swap. i am on a budget so any other ideas are welcome.

 

you can use the whole block... if you try using internals from one block to another, in theory it should work, but the blocks are identicle, so why trade out internals?
