3800 SC III swap... What do I need to salvage?

You said you were going with a 97-03 setup (series 2) So unless you put a gen 5 supercharger on and replace the gen 3 that is on there now (theses have the DBW TB that have a different bolt pattern that the 97-03 TB's) then you don't need to have an adapted plate.


If you're going to be using a 97-03 setup you can use everything...TB and all. Everything already fits and is designed to work. The adapter plate only bolts up a 97-03 TB to a 04+ supercharger wich utilizes the DBW TB.

Ok, I guess all this Gen 3/5, Series II/III, etc talk got both of confused, lol. I'm doing the SC III. I'm keeping the Gen 5 SC. I'm going to downgrade the necessary parts to use a cable throttle. This means the wiring harness, ECU, and throttle body. Is this right?

btw, it's being delivered on Monday. To have it delivered to me, I'm paying $1200 for the engine (has all accessories and only 70k miles), trans (G Comp package with shift paddles), wiring harness, ECU, BCM, PK3, ignition, and key. Is there anything there that I'm missing from the Grand Prix (I gotta defeat the VATS)?

Use the OBD1 or (97-99) OBD2 computer, and just have Ryan at GMtuners.com bypass VATS for you and do a base tune. You'll need the OBD2 computer to use the 65E-HD trans. Working with a post 2003 computer is absurd. There's also no specific need to use a Series III computer, so go with the old school electronics. Old wiring, new motor with better supercharger and rods.

Also, just buy the ZZP TB adapter for the N* or LS1 TB for the GenV charger and be done with drive by wire.
