What is the best piston ring gap when building the h22 motor?

I want it tight for better compression but dont want it to smash into each other either.

I have Wiseco pistons with rings...11.9-12.1 compression ratio after .025" milled

 

they didnt come w/a spec sheet?

if not i have endyne/wiseco pistons w/endyne spec sheet...i can tell you what it says

 

please do tell me....

the pistons came with papers but nothing about ring gaps and how much to bore the cylinder walls to...

 

whats the bore?

 

stock bore size of 87mm...

I'm installing new darton sleeves and need to know what is min. and max bore size they recommend

 

well this is off my old spec sheet..if i find the new one ill tell you if its different:

piston to wall clearence:
na:.0030"
fi: .0031-.0032"

ring gap:
.014-.015"

did you mean:

NA:
0.030"

ring gap:
0.014" - 0.015"?

yep, fixed....i wish i had the newer sheet...

 

hmmm, i thought most places wanted you to send the pistons in
with the block so they could bore it to exact specifications

yes that is true....but if you dont have the spec sheet...how would you know


called wiseco...specs for na with darton is...

piston to wall = 0.0035"
ring gap=0.012"-0.015" or 0.017"...got to look at my email again...

thanks!
