LSM single turbo kit on top of a H/C??? Thinking about adding FI to my 99 SS. I will list my current mods below. I am currently at 414rwhp/387rwtq through my 12 bolt and 4.10s with my chrome 17x11 AFS Zr1 w/315s. I am considering the Ls1 Motorsport's single turbo kit. Here are my current mods:
ARE stage 2 ported Ls1 heads with dual springs
Lunati cam : 226\234 .554\.575 112
LS6 intake
ported T/B
SLP 85mm MAF
whisper lid w/ k&n filter
SLP CAI
SVO 30lb injectors
ARE ported oil pump
Grottyohann headers(1 3/4" primaries to 3" custom flanged collectors)
Grottyohann y-pipe(Rapid Motorsports flanged my header collectors, made flanged 3" cat by-pass pipes,flanged the Grott y-pipe)
SLP Loudmouth exhaust
1LE trans mount
RAM 6130/402 VDS clutch
Moser 12 bolt(HD Eaton posi, 4.10 gears, 33 spline axles, and TA cover)w/ traction control and ABS.
BMr tubular weld-on SFc
BMr tubular LCA
ED Wright tuning (28' timing, with 7000 rev limiter)
removed EGR and emissions system
I plan on upgrading the entire suspension, swapping from 6130 disk to a 910, and adding a Borla muffler instead on the LM resonator. What do you all think about me adding the turbo kit? My SS is a 1999 with 18,000 miles.

Re: LSM single turbo kit on top of a H/C??? i'm pretty sure your compression is 10.8:1 .. much to high to get any amount of safe boost with a turbo.. remove those heasds and get some factory 6.0 heads and you are set.

Re: LSM single turbo kit on top of a H/C??? That cam's gotta go. And I'd agree about swapping out the heads. Flow numbers with a power adder aren't as important as they are without one. The turbo will make up for the lower performance. I'm not saying get crappy heads, I'm just saying don't worry about getting the most flow out of them as humanly possible. The difference won't be as visible with FI.
Re: LSM single turbo kit on top of a H/C??? How is 10.8-1 too much compression for FI? Stock compression is already 10.5-1 and supposedly that's safe enough for LS1MS turbo kit.
