I'm planning on doing this in the spring time was going to keep it on the DL but i'll post what knowledge i have of the setups and others can chime in on things i've missed.
You will need to do some turbo research to see what size would work best for these cars as a junkyard one prob wont do the trick. a great way to educate yourself is the turbo tech on Garrett's website. I would recomend setting a HP goal and finding a charger that fits within that goal while leaving you some positive room to grow. I'm guessing you are not building the bottom end at all and boosting svt's is new to me but I dont see very many running past 10lbs..most of the time sticking near 7. Too large of a charger will take too long to get there even with the remote factor and the quick spool up they are known for. A small charger will leave you no room to advance HP wise as they it would only be good to to a certain level and then just blow hot air after exceeded. You will also need too look at where it will be mounted. Is it below the oil level in the case? If so, you will need an electric scavenge pump to return the oil to the crank case and lines to feed and return as well. The wastegate I have'nt looked into yet, and am curious as to what others think. You could run an internally gated charger, but most of the time those are factory sized, smaller setups that will really prob only net you small gains. After you get all that figured out, you need a tune asap.
As you can see there is a lot more than just bolting it up and boostin'. And, chances are if you found a turbo at the junkyard it's too small and prob needing rebuilt. As far as I know, and others I've talked to no-one has done this yet, as i've never seen it and a few mods i've talked to have not as well.
