I have changed me mind again and i am now going to build a "2.1"? ZVH I have all my parts ready and i am using forged XE pistons, Now i know i have to modify the conrod to fit the bigger gudeon pin.
But is that all the work needed to do to the piston and rods?
Also i am using a 2.0 Blacktop bottomend so all i need to do is rebore to 86mm and do the ushual ZVH mods?
Any help/info would help.
Cheers Stu

TBH i plan on doing most of the work my self, I was just looking for information as i have not done a 2.1 before but i have done a 1.8 and 2.0 zvh.

Yes you're on the right track.. as long as the piston clears the rod and the skirt clears the oil squirters.. you're good to go..

Ill see how things go. So the conrod needs to be opened up to 21mm and will need to machine abit of the skirt and i am done?

Also i am getting my head ported while its off.

hi there the water pump on the black top is not the same

^^^ yeah, you'll have to swap pump to a silvertop one as the blacktop rotates the wrong way. I'd also check the block heights or speak to someone who has done a Blacktop ZVH before
