Hi fellow car fiddlers, I'll be removing my cylinder head in the next couple or three months (to up the valve sizes) and was toying with the idea rebuilding the bottom end in 2.1 form. I guess that you use the 95.5mm diesel throw crank and some new pistons. I have a couple of question about this - I guess the extra throw will reduce the revability even with big valves so is it worth it? Piston wise I don't have a clue what to use - Do I have to purchase new pistons or can I source appropriate pistons from another engine. Anyone any idea what the diff (pwr and tq wisae) would be between a BVH 2.0 and BVH 2.1?
