how to do it correctly?
I think I need to use the 4 pistons, one side v-twin engine!
What do you think about this?

 

What kind of hammer will you be using?

 

 

1 halve of a v6 = 3 pistons... you need more better math teachings

 

Great sense of humor !!
I thought people here would guess that H22 has a sleeve which can be increased to 89mm!
The fact that the engine v6, on one side of the piston 3, I also know.
If you do not understand the question, I will try to explain !!
From v6 engine, you can choose 3 of the piston, which will work correctly in the direction of rotation and fit valves
4 must rotate the piston 180 to fit valves, but it will rotate in the opposite direction.
I saw a reverse head H22, there are deploying all 4 pistons 180.
In my case, one piston will not work properly

 

The problem with 89mm & J-series pistons is the 89mm J32 has steel liners. Those pistons will wear away to nothing after a few minutes. Only the J30's had FRM liners, and those pistons are only 86mm.

You can re-sleeve the H22 with iron liners, but then that shoots your whole save a dollar idea all to hell. At that point the K24 pistons would be easier & a better option than taking apart two J32's.
