I currently have a stock 1989 3800 with auto trans that I have put into a trike. The drive line has about 80k on it.

I also have a SC from a 92 or 93 Buick Park Ave complete with crank pulley and intake.

Questions: What gaskets will I need to install the SC? Intake, valve covers?
Will the ECM need to be changed out or just re-programmed?

I'm sure I'll have more as I go.

Thanks.

The Series II motors use different heads, as the blower doesn't leave room on the inlet manifold for injectors.
Check Series I, but you may need to swap heads as well. Maybe easier to turbo the beast instead of using the supercharger. There are youtubes of earlier 3.8s turboed. Check out the guy who did this one

Don't the 92-3 buicks have the series 1 motors in them too?

If for some reason the SC won't fit on the 89, I won't add the turbo to it. Don't have but $400 in the entire Toronado driveline and the SC.

I didn't find a good pic of the series 1 heads, but check and see if the supercharger inlet manifold has injectors in it like the non-sc manifold does.

cool - some stuff I can think of:
crank pulley and the other pulleys
fuel rails and regulator? or maybe same as n/a?
ecu I assume, unless someone can reflash existing one
Does it use the same controls as n/a? SII uses MAP, don't know if Series I does or not.
Should be do-able-ish, you'll want to find a factory SI s/c unit to at least look at.
Prob be easier with a donor for all the bits and pieces.
If you can weld, it still might be easier to do the turbo?
(Sell/swap the s/c for a used turbo?)
