2.2 Ecotec turbo'd

Ok, as I gather info for my 2.2 Ecotec/5spd swap (from 02 Cav z24)into my 92 GTZ. I am wondering if anyone successfully turbo'd the ecotec in a Cav, what did you use to do the setup? I am basically going to need a custom exhaust mani for my swap since the cavi's downpipe is too high for my firewall to clear. it comes out right where my steering rack is unfortunatly. I would really like to use the Saab 9-5 Aero's setup. The 250hp version. I know its the 2.0l, but without doing the crank/rods/pistons the compression ratio is not that far off from the turbo'd version. So i'll just leave it as it is. If I blow rods, I guess thats all the more reason to upgrade to 2.0. Now if anyone has any links or they have knowledge about this setup please post here or email me. I appreciate all the help...
