Contact CP Pistons, they can make you a set of pistons very similar to the CTR pistons in an 84 mm bore, or any other bore if you like. Just thought I'd let you know.

I do not know where this information is coming from. I work at an Acura dealer; OEM oversize pistons are 0.25 mm over, not 0.025"over. Look it up or call your local dealer to confirm.
