i have too. if f20 pistons work and work great in a k24 motor and f22 pistons fit and work it shouldnt be a problem. it is a little bit of work. but should be fine. im not saying for this guy to do it, it was an idea. but im doing it. but why is it unreliable to use other parts from something else that may work. there is a guy on there that is goin to use k20 pistons in a j series. you can mix and match parts and work great or better the others.
yea but all you have to do to make them fit together is to mill a little off the top of the tsx rods. all you have to do is weigh and balance the rod. but one of the clutch masters cars used to run f20 pistons and made 13.2.1 compretion. but milling the head is not keeping it simple thats just as hard to get done or harder. here read this:http://www.k20a.org/forum/showthread.php?t=43299&highlight=s2000+pistons
you can use F22 pistons out of a S2000 and use tsx rodes 11.1 compretion and they are cheep than 09 tsx pistons, you dont want to run anything on stock k24a4 pistons they are thin. and the reason you can use any of the k24 series pistons exept k24a2 (tsx) pistons is because the tsx pistons have valve releafs and the rest dont, its kinda the oppesset. and if you are going to swap the head ur going to need a k20a2 oil pump,chain,tentioner.
