Lude Generation

I cant find typeS so regular H22 pistons will do the job. I know there are new ones from DNJ but i prefer used OEM if they are not damaged. Also still need a few valves

Won't you need to let people know what pistons you need as there are two different piston options and it varies on a block by block basis?

Check page 7-6 (page 175) of the 5th Gen Service Manual. I have no idea if it makes any difference but I've been looking into rebuilding a H22 and noticed when reading that section.

i may actually have a spare set of a8/atr/type S pistons, ill try and check - Jackson Bondy is right about the "A" and "B" variants of the pistons but you can run either in a block, you'll just have a tiny bit of piston knock. its not ideal but i know of poeple who have run them just fine, plus some blocks like mine are awkward as its supposed to run ABBA....yes, an abba block but some block are all AAAA, some can be AAAB, luck of the draw really.

Is A or B the tighter setup? I didnt check the pistions code yet(didnt see any), but all cylidners are 87,003mm from front to back and sideways aswell

All my Pistons in my H23 and also in my H22 block are type A !

If drax carnt help I should with any luck have a set of 4 out of a jdm 4th gen h22a
in a couple of weeks. I have no idea what star there in till I get them out I am putting Atr a7 piston's in instead. Once there out i will send you some pics. If any use to you

I hope to finish my motor as soon as possible, but if i cant find others earlie, id be thankful of corse. Do you already know the pistion type? marked on the Block above waterpump. How much you want for these would also be good to know i will calculate a usable setup with JDM pistions.
