Building an h22a starting with the block and moving up.
block is getting sleeved here shortly, just looking into what pistons to get

Im looking to run a high compression motor with a direct port nitrous shot (~150 shot), built top and bottom end.
(head = new valvtrain, crower stage 2or3 na cams???, ported/polished, etc etc)

I want to keep the stock bore (87mm) and stock rods.

looking at the wiseco 11.5:1 pistons. anyone with experience with these?
will they hold up to nitrous? and high rpms?
looking for all suggestions here good and bad, still in the beginning stages of this new motor

 

wisecos are good arias srp probe rods eagle rods manley rods cp pistons are good

 

hmmmmm
so now its a tossup between CP 11.5 and wiseco 11.5
any other comments/suggestions?

 

cp are greats pistons

 

any pros/cons of the 2???
or a link to a thread on it?

 

why are you sleeving if your gonna go all motor save some money and get forged pistons that will run in stock sleeves

 

FRM sleeves FTL!
no bueno with lots o N2O
and one of the stock cylinders has a scar.

 

The Wisecos come with more features off the shelf than the CPs do. They come with moly coated strutted skirts and offset wrist pins if I'm not mistaken. CP would charge extra. CP makes very nice pistons as well. (I have a set in my current project) It just seems like you get more for your money with the Wisecos

 

stock sleeves will take 100 shot no problem but yeah with a scar i would replace but not sleeve not worth the money unless your gonna turbo

 

Good info on the pistons thanks!

and i plan on running a 150-200 shot direct port shot and i dont wanna risk it
plus i got the sleeves and installed for under 300

 

Sleeving will be a must for dependability when spraying nitrous.

IMO anyway.

Personally I'm going to be running some arias pistons in my H, i think you'll want to go with a bigger dome piston if you really plan to run crower 3's, i ran them with some 12.1:1 pistons at altitude (which amounts to about 11.1:1) and they really didnt make power until about 7.

 

god damn $300 for sleeves and installed were did you get that hook up

 

ive been looking and cant really find any pistons higher than an 11.5
any ideas on who makes some good ones around 12.5-13?
and if i decide to go crower 2's is 11.5 going to be high enough?

 

11.5 would be could for nitrous anything higher than that on a big Nitrous shot would require race gas.

Good lUck

 

i already planned on running 110 vp gas.
just cant find any pistons over 11.5 without going custom
