when putting turbo pistons....stick to factory ring end gaps??

sup pplz got my pistons and rod combination (je9:1 and

eagles)aiming at getting a little over 12 psi as max boost on my ls/vtec to keep it as a safe daily drver. now i'd heard that the rings should be a little looser than stock but im very skeptical bout it.....................what gap have u guys used

also i have the arp's head bolts...........what would be an ideal torque setting for them

thanx
ne input will be great

Ususally what we do is run the top ring at stock gap, and then gap the second ring pretty loose. The loose side of stock specs.That seems to work well.

that's my theory too, but since the car is going to be turbo i pretty thought the gaps would have to be different cause of the extra load that is involved, and since u guys been the done that i'm trying to gather as much usefull info that works........... u know

If they knew you were turbo charging and gave you those specs, then I would just use what they give you. If they just gave you a range then go on the loose side, because you don't want the ends of the rings basically welding together and galling the cylinder walls.
