Generation IV Internal Engine - ls2 block

Hi guys, I did some reading but cant find a common number. I am doing a turbo ls2 and would like some feedback on what the blocks hp limit would be.
Thanks
Paul

sorry for hijacking, but would also like to know how thick r the sleeves? is there anybody pushing to 1000+rwhp? how do u compare L92 block strength to the LS2s.

I should had started my own thread, but it would be heplfull to gather all this info together.

I've read stock LS1 blocks will lose ring seal with big power turbo/supercharger motors that have lots of street miles put on them. The solution for many was the LS2 block.

There are a number of turbo LS2 buildups running stock LS1 cranks, forged rods/pistons (364ci), AFR 225's and LS6 intakes with ported TB's making 1000rwhp+. After a few hundred passes the cylinder liners will crack at the top of the bore. Remedy- simply buy another sub $1000 block and go back at it. For a production aluminum block the LS2 is hard to beat for strength.

i had a ls2 that i sold last spring with a procharger and my machshop guy told me a 1000HP was the limit and that was the cranks(STOCK)limit and i was only building for 650 700 hp so thats why i went with the LS2 block and crank for that build,and dont get me wrong,that was ARP studs and bolts everywhere ,forged pistons,rods

Ive got 8000 miles on my 1003 hp LS2. That's engine dyno not rw.
16 lbs boost all the time. Here's 23 second run to 200mph with it.

Good lord that makes me want an Ultima so much more than I already do.
