What is the bore size of a B16a First Gen., I believe it's 81 is that correct? I'm looking to get some Type R pistons at that 81.25 witch means I have to bore the block, I think. Any other piston help would be great, like other recommendations or anything.

Thanks

yes, 81 is stock, the 81.25 is the over bore, dont do it unless your cylinder walls are in bad shape and need it. i say get the 81mm ctr pistons for that motor, its a good combo :)
