H22 crankshaft

Hi,

I am looking for a crankshaft for h22.
It can be from h22a, a2, a5, a7 or a8.
All offers to PM.

are you sure I thought there was a difference between the h22a and the a8 and a7

^ Yup. Not knowing what you want to do with it but be aware.

a2, a5 and some H22a = 50mm
a7, a8 and some H22a = 55mm

Obviously 50mm mains cranks cannot be used in A7 or A8

I have two blocks in my garage h22a2 and h22a7. so it does not matter to me

If they are both unmodified it would be best to build up the H22a7 rather than the a2

The plan is to rebuild h22a7, but if I will be able to get normal crankshaft, I will put PDE pistons in a h22a2 bottom end and use h22a7 complete head and intake, exhaust manifolds.

why?

Higher comp but he says he will whip the PDE pistons out and put them in the a2, so it doesn't matter either way.

I have an a7 that I need to strip down and the crankshaft will be available. Where are you based?
