The turbo 3.8L engine is all original except for coil pack and is currently in a numbers matching 1984 Buick Regal T-Type. The motor has 115K miles on it and is located in Mt. Morris, MI. The reason I am selling is because I just bought an 1987 motor and because there is a high-pitched squeeling coming from it. I'm not sure what the problem is and I haven't had it checked out. The engine still runs, so you can hear the problem before you buy. Engine comes complete with wiring harness, injectors, turbo, and some accessories. Asking $1400 o.b.o.
