Hey all. I tried searching but to no result. I am rebuilding my H22a. Can I use USDM H22a1 parts? Or do i have to use straight JDM H22a parts such as rings, bearings etc etc? I know H22's have two different pistons in it and all that. Just wondering if I can use USDM H22 parts instead of paying a **** ton for JDM parts.

Thanks guys

 

yes, h22 and h22a1's parts are interchangable

 

even internal wise? Can I still use H22a1 rings, bearings, and everything on a JDM H22a? That would save me alot of money

 

i'm not 100% sure, but i believe they can be

 

Yeah the only difference should be piston height, even your rings should be the same, and obviosuly make sure you hone to spec and set ring gap properly.

 

Thanks guys. I will be tearing it down within two weeks. So lets hope H22a1 parts match H22a

 

Right. Piston height is the only difference. I've heard the cams are slightly different and heard they're the same but I'm not sure. Never had any to compare myself.

 

Do you know what year your H22A is? 98+ will have larger mains than an H22A1. Although, you may not need to worry if you are just swapping pistons and rods.

Piston height?

You mean compression height?

If so, you're wrong.

The difference is the displacement of the dome. (jdm are 1.7cc IIRC)

 

The H22a is pre 98.

You're asking the questions. We're giving the answers.

 

haha I know I know. Should I just go ahead and buy H22a rings, bearings and such. Then stuff like full gasket set, oil pump, water pump etc etc be purchased for an H22a1 for cheaper?
