You know what would be cheaper than turbocharging a Series 1 3800? Swapping in a Series 2 3800.
I had my Series 1 3800 for 8 years and never really could get a decent amount of performance out of it until I ported the heads. Porting the heads was the absolute biggest increase in performance I ever had in that engine. I had a CAI, roller rockers, exhaust, ported LIM, and those didn't do much of anything because the heads flow like complete ****.
In order of heads flowing from worst to best:
S1 3800 < S2 3800 < 3100 < 3400 < 3500.
Yes, you read that right. GM 60*v6 3100 cylinder heads flow a LOT better than even Series 2 L67 heads do on a flow bench. If you want to open up a Series 1 motor, your best bet is to get 3-4 grinding stones, a dremel, new gaskets and fluids, and go to town on the heads. I can provide pictures of what I did if you're interested. I'd sell you my heads (since I'm getting an L67 swap done as we speak), but they are for the N/A 3800'* and you'd have to have the injector bosses drilled out in order to use them on the supercharged S1 3800.
