Oops ya just saw that in another post. Mast Motorsports make the 12* heads, although based on my experience I would try and find another company as I didnt have a good business dealing with them. I ran the turbo kit on pretty much the same setup you had (I had the compstar crank in another LS3 motor that is getting rebuilt). I think on low boost (8psi) you can make 700-750whp and close to 800wtq no problem with the right tune. That's pretty much as safe as you can go. I would watch your oil, as the turbos will eat up some oil. I was literally running almost the same exact setup you were before i pulled my motor out again. The motor itself should be able to standup to all of the abuse you throw at it! by the way, make sure you upgrade your dampner (to ATI IMO) and make sure you have an upraded oil pump as well. It runs a heavier duty cycles due to the turbos.

well your going to gain 40 ish HP from the CI increase, but you will loose HP from the comp dropping. The nice thing for you will be your a forged motor now, so when you do that just up the boost to 12-13 psi and have a BLAST with it!.
we did 720+ RWHP on only 9 PSI on Uniq's car a few weeks ago with all stock except our cam. You can make some great HP with TT kits a few things to do: make sure you have turbos spec for your motor make sure your cam is going to work with TT and the Ci you have HEAD STUDS! thicker deck heads fuel system One thing to think about is maybe do stock CI( stock crank) and do pistons and rods. your motor will love you for alot longer that way! Plus you can push 1000 Hp all day long with this setup also if you do all this you will make a awesome setup and have more power than you can ever use. Dont be discouraged that you will be down a tiny bit on the stroker cause with the 418 you will be able to turn it up and do it safe, thats kindof the point |

I also have a set of ls9 heads that are a much much better casting and thicker deck, better valves than the stock ls3's if you start looking for heads.

well guys thank you for the info. I already have the 418 block and set up..so now I dont have a choice. I was told that wall thickness wouldnt be a problem for a limit of 20 psi as long as i stood under 418 cu. I was told that a 427 would is not recommended with boost at all unless I run iron. But it seems I will do fine with my setup thus far. I mentioned most of parts, and measures taken on my replays. i guess we are reading and typing at the same time.lol Cyber and pyro, will be getting a phone soon. I just need a turbo hug. i am nervous I have to say. I like to stretch the envelope. And this is the strongest engine setup i have ever proceeded with. Basically I am new to the game.
