Piston Questions
I’m rebuilding my Honda H22A4. As you can see, its sleeved, so the walls are a different material than the original FRM coating.
I was wondering if I could use oem/oem replacement pistons with different rings.
Forged pistons are also an option, but can I run them without a tune? I’m also worried about expansion size.
Just aiming for stock power numbers, and I have to stay untuned to keep ATTS, any advice helps!
