    hey all,
    I have a jdm h22a with all the basic mods ihe msd 6al and fuel rail/reg. I decided to do an all motor setup with optional nitrous. I plan on using 75 shot zex dry setup. What c/r pistons would you reccommend for that size shot? and any specific brands of pistons you reccomend? Funds wont be a problem either....

    TIA!!!
    Dave

    With the right amount of fuel you should be able to run a 75 shot on stock internals. If you want to put in some better pistons just in case pretty any aftermarket piston will work. raceeng.com has a good selection of pistons id you do change them.

    i may be incorrect but isnt there an issue with after market pistons in H22's? couldn't he just go with type S pistons and up his CR to 11:1 maybe run a 60 shot instead? with proper tuning he could still run a 75 shot. thats what im doin ;)

    hmm yeah id like to know if certain aftermarket pistons would not be recommended for an h22a. Also I can get a really good deal on some JE 11.5 c/r pistons standard bore would those be able to handle 75 shot? and would that compression be ok for nitrous? Thanks a lot guys! :D

    again anyhting is possible with proper tuning, and if you have forged bottom end, its less likely to die. especially considering that aftermarket pistons have probably resolved the ringlands issue. like i said, i'm not totally sure that you can use aftermarkets. thats something someone more knowledgable would have to address. you could tho run a 75 on 11.5:1 dunno what kinda gass tho, i think that is sorta high for 93 octane, unless tuned very well. but i may be mistaken.
