What is the largest bore you can do on d15 block? I would fill the block to bring back some of the strength to the walls. I know this is a pipe dream but is 81mm completely out of the picture? I can still dream can't I? lol What is the wrist pin size on b16 rods and wrist pin sizes on d16 rods?

 

81??

Why dont u run 1 big oval shaped piston, no water needed :P
ive seen 79, i think thats the max i would ever try running
pistons will be very pricey, custom

 

Oval...hmmmm I think you may be onto something. :P Naw just curious. 79mm ehh? I could work with that. thank god for the vx.

 

what u got planned brother
leak it out

 

damn, must be nice to throw $2000 at a puny D15 block to sleeve it and have pistons made for it.

 

I'd be happy with 79mm. But now since Bone shattered my dreams on bringing up some old knowledge that the vx and d15b cranks aren't the same I need to find me a d15b crank now. This is always something everyone has laying around. lol. Custom rods and pistons weren't in my budget so I may have found something that could work.
