Nice, keep updating. I'd like to know how that works out for you.

yeah it's an jdm block, this video is to show that you dont have to buy mahle gold series pistons to run forge pistons on the FRM h22 sleeves, I got a cheap set of probe forge pistons and got them custom coated for testing..500 miles with no problems yet

Just a question, I thought the H22a4 was supposed to be open deck? Was that a pic of the the block that came in your prelude after rebuild or was that an earlier h22 block that you built?
