Twin Charge
Ok so I have seen a few different cars on here that have had it done.
I am hella intrested in this set-up and would like to know more and what parts I would need to make this happen. What size turbo everything. Can anyone help me out?
Also I was talking with a few people about this before but they just pushed me off saying something about tuning it. But I would really like to know what it would take to throw a Turbo on the LSJ with the S/C....Anyone?

Redline twincharge
PowerPaq, Garrett 3076WGR Turbo, Sprint Springs, Golden Eagle head studs, Titan Headgasket, 3.8" pulley, custom small tensioner pulley, BIG Injectors, HKS 4" Megaflow filter, 8k HIDs, Drag Wing, Custom 3" Mandrel Stainless exhaust, E-Boost2 EBC, TurboSmart Vport BOV AEM Eugo Wideband, 2-10"
FYI the car is tuned with HP tuners as well as the SMT-6. The SMT-6 runs the 4 secondary 60 lb/hr injectors
The cobalt in a youtube twincharge used a super16g
Equations
Total pressure = [absolute pressure + turbo boost (psi)] * PR (pressure ratio of sc) = Boost pressure (boost you see @ gauge) - absolute pressure
Example
Total pressure = [14.7 psi + 4 psi]* 2 = 37.4@vaccum
boost gauge pressure = Total pressure - absolute pressure = 37.4 psi -14.7 psi = 22.7 psi
A PR of 2 I think can not be achieved with the stock pulley, it needs to be larger, such as the 3.8".
If you used the stock pulley, the turbo psi should be at 3 psi.
Boost gauge pressure (with turbo @ 3 psi) = 20.7
I doing research with this, I'm going with this setup soon. I will be using the stock pulley, and I'm looking for a turbo, and doing calculations, also, I will switched to 60's and as you see in my sig, I have a return-style fuel system
