I wondering what engine from the LS's would be the best choice to turbocharge? I have a grand national now and am ready for a new project. I heard the LS2 is good with dished pistons?

Any help would be great!

Thanks,
Chris

how much power are you looking to make?the ls2 block is a sturdy piece-we are making 1700hp on a stock ls2 block.

I'm not looking to make 1700hp. Maybe in the future lol
when you say stock LS2 block, is that a stock long block?
If not what internals and heads are you running?

Thanks for the help. I have also read that the Dart little M block is very good.

With the right prep it will take alot of abuse.
You would want to pin the mains and do an o-ring deck and head studs or step up to the big head studs to hold the big power on an LS2 block.

I'm still trying to make this block decision..

I think there more to your ls2 than a strait stock block!!! But would be the best starting point then down the road send it out to V.S to make the mods to go big power.

I'm really torn between getting a LS2 long block complete with harness and throwing a turbo on it.
Or go with LS2 short block and go with better crank, pistons,rods & heads.

And now I read that the dart blocks are very good.

Hmmmmm

i would advise putting a turbo on stock ls2 pistons-step up and buy some forged pistons and rods


the only block Dart makes for the ls is a billet block

The Dart block i was looking at was the little m. Does not have to be a LS block.

Does the stock LS2 still come with hypereutectic pistons??? How does the rest of the rotating assembly fare as far as strength?? I've got a 2007 c6 corvette with a d1sc procharger and it's making 551 at the wheels... How much farther can I push it??? I know from the factory they are damn near 11:1 compression...

I'm not trying to hijack your thread, but I figured the info that gets responded will also help you out Chris!!!!:D

Didnt you do your o-ring set up on his block?

I've thought about welding the hole shut in my block where the rod exited and throwing it back together.
With the mains pinned this time. I got about 15 passes out of it last time and the mains were trashed. I broke a rod bolt or the rod bearing siezed. It was hard to tell from the carnage.
It took out the block, 3 pistons, 2 rods, 2 valves and the crank.:smt089

yes, the block is o-ringed, but that does nothing for block strength....thats to keep the headgaskets on the motor...

when we say stock block we mean stock mains, stock liners, unmodified casting as provided from GM...
