Should I re-ring and re-bearing my lq4 for boost?? I’m somewhat rebuilding my lq4 for boost. So far I have the block on a stand with just the pistons in it.
I putting in a BTR stage 2 turbo cam, new melting 295 oil pump, new water pump, new double roller timing chain. 317 heads cleaned and refreshed with double springs, seats and seals etc...It’s gonna have ls9 mls head gaskets and arp head bolts.
Ive been seeing a lot of people Leaving their rings untouched with their turbo builds and It works for them. I most likely am gonna install new crank and rod bearings. Should I keep my rings the same? Or should I get new rings and file them accordingly? Btw I don’t know how many miles are in this block I just assume it has 250k.

Most guys don’t touch their rings, because they usually don’t touch the short block. If you’ve got the rings out of the short block, by all means, open them up a little. How much boost you plan on making?

Im gonna install new rings, I hear moly rings will flake under high heat from boosting and will damage something. What other ring types are out there? I’ve only run moly rings before but this is gonna be my first turbo build though.

we've been 15/16 psi on stock ring gaps L98 and LS3. making over 900rwhp through a converter an auto and they live the dream.
the photos you see of the middle ring land of the piston blown out that are blamed on rings butting up..... I would argue strongly that's from detonation, not rings butting up

I'm playing around with a 6.0L to build back up with some gen4 pistons and rods, and a stock crank. im planning on boosting it to about 15psi. is .028" still a decent gap size for the top, and do I need to open the second one more at this boost level?

its amazing how old some of this posts are but how far we have come in such a short amount of time. who would have though 1000hp with some gapped rings on stock blocks would be normal now days?
