Hi I'm new this forum I don't know 100% about certain parts but I have 91 Prelude Si 4ws that has been sitting for nearly 10 years. I want to bring it back to life but realize there was an issue with the pistons or cylinder that needs to be replace if anyone knows where I can find the good quality parts and/or find another Engine B21A1 even though its rare to find would greatly appreciate it.

We bought new pistons and oem rings.the frm (fibre reinforced metal) cylinder liners are harder than the piston and rings which wear out quickly. ####Do not attempt to machine this block or bore the cylinders..###.
