Ok, I have a 93' Vtec lude with a H22A1 and I'm looking into putting type S pistons in it. What parts will I need in order to do this. Also, will it still pass smog in California? I was reading another post on this topic and it was talking about the cylinders being labeled with either a B or an A, depending on the size of the piston. Where is this label located. Will I have to bore the engine at all for this upgrade? I plan on just honing it. Also, I was discussing things with a friend of mine and he said that I shouldn't do this because I will put to much strain on the rest of the engine, bumping the compresion like that. I do currently have a blown head gasket, but I am putting a new one on while I have the head off. If N E one has done this, please let me know how it is working out. Thanks for the help, J
