i have a jdm h22a swap. Im lookin to freshen it up a bit before it makes it into the car. My main question is would usdm h22 parts fit. Are the blocks and heads the same completly besides higher compression pistons. Im doing the head over so i assume the valve seals would work as well and cam seals from usdm dealer. What about oem usdm head gasket? What about our oem water pumps and oil pumps. What can i use from my honda dealer and what do i need to go else where for...
thanks

 

all the usdm parts will work. there are two types of valve seals, one type has a rubber coating on the top. dont get that type, they are very easy to damage while installing. heres the part #'s you will want: 12210-pz1-003 and 12211-pz1-003 intake and exhaust. honda has also had an issue w/ the oil pumps as well. the groove for the small o-ring on the back of the pump is not machined correctly and does not come w/ the o-ring. if you order that o-ring from honda it wont fit. you will have to find an oring from somewhere else other than honda. other than that you will be fine w/ all usdm parts.

 

what are the ones you gave my from? different engine or just a different version of h22 seals
