How much boost can you run on a lq9 with 243 heads

[slowWhitez71]

All right gays I need some input I have a lq9 with 243 heads and im wanting to go turbo and I dont no how much boost it can take or how much is to much! Plus I dont no what size turbo to run! Thanks for any help thats given!

thats a really open ended question. the motor it self i think 13/14 is the limit on stock bolts? but your limit will be the motor/ fuel/ supporting mods.... everything has its limit. on a stock 6.0 with a stock 4l80e with 91 oct id think 10-12 psi on a really good tune?

Are you talking rod bolts, or head bolts that are limiting factor?
I've been kind of wondering myself... I have an LQ9 with cnc 241s and about 10.8:1 c/r that I'm considering putting a turbo on. I have Katech rod bolts, but just OE gm tty head bolts...

Depends on who you talk to head studs are good for big boost, but dbrods has found the rods to be the weak link as of late.
