What is the maximum safe hp with a LS2 block and how much boost can they handle? I am trying to decide on a 6.0 or LS2 (I already have) for my turbo project.

I know Mike's running an LS2 block in his CE and it's going pretty quick for a street car

I'm hoping to find out if mine will live on the dyno soon, i'd like to see 1500 minimum at the crank.

We are gonna push it too, but it will be later in the year, so good luck to all before us! I think Mike's pushing 1100+ at the flywheel, maybe he'll chime in on this.

A ls2 block will handle anything you slow guys can throw at it.. It will be the next block put into the Formula,of coarse after it goes through W2W

I know of at least one Vette guy that blew his C5-R and replaced it with an LS2. No problems thus far with the LS2.

You better watch your mouth ....some of these guys are bringing big guns to the fight this year!

I guess you can talk a little smack since you are the LS1 EFI Series champ.

So your saying my LS2 with a callies or maybe a LS7 crank with oliver rods,cp pistons,good heads ,custom cam and a gt-47 w/ air to water should be safe with a good tune.

I know the LS7 uses a different crank sensor, waiting for someone to make it work with a LS1 computer. I get a decent price since I work at a GM dealer.

Newbie question: When someone puts a LS2 block into a Trans Am, Camaro, vette, etc... What does that eliminate? A/C? P/S? Any of that stuff? Any way you can keep it?

Wow, I’m honored to just read this thread.
Some of the biggest names in the FI world taking a moment away from working on there 8 and 7 second cars to answer such a seemingly simple question.
Guess you guys are the only ones who can speak with first hand experience.

How do you have time to race?

Sorry, I’ll shut up know.

Thanks for taking the time to answer my simple question. I dont have the money to build this and wish I would have built a 6.0 instead. I am also probably using a 7.0 pan and dry sump oil system. It will be seeing 22+ on race gas and @10-12 daily.

everything bolts on. Knock sensors are a little different, one AC bracket bolt is a little different, but the rest looks the same.

So I guess there is a way now to keep your knock sensors functional with the LS2?

Hmmm.. I smell project Twin Turbo LS2, with A/C and P/S, one day for me....
