Yes a 89-93 3300 would bolt in just fine. The '93 3300 had slightly
higher flowing heads but the engine internals are the same. You could
also drop in a larger 3800 from say a 1989-1993 Buick Regal. You
would also need to swap the ecm if upgrading to the 3800.

I have a 93 Cutlass Supreme with the 3.1 L (not 3100). The 3800 wasn't an
option for this car, but its the same platform as the Regal and Grand Prix.
Is there any reason why a 3800 wouldn't fit? Could I use a more modern 3800?
How about the supercharged version (I'm guessing I couldn't just add a
supercharger to a normally aspirated 3800, since the compression would
probably be too high). Also what about a turbocharged 3.8 L from say a Buick
Grand National? Would that fit, and how would the power/reliability compare?
BTW I have the 4 speed (OD).

The 3800 will also fit in your Olds Cutlass Supreme. But to swap a
3800 (90 degree V6) in place of a 3.1 MPFI (60 degree V6) you would
also need to get the wiring harness from donor Regal. The Buick Regal
is the only 89-93 W-body platform to have the 3800 as a factory
option. You would also need different engine mounts&struts (dogbones
as I call them), and perhaps some of the coolant/ac line plumping.
The 3800 Series II Supercharged is an awesome swap, but you would need
to buy special internet wiring adaptor/harness to make wiring 1997
technology to 1990 technology bearable.

As for the guy with the Olds Ciera 3300. The 3800 is the same engine!
The 3800 is just a stroked 3300. The swap is very straight forward.
You just need the ECM (only because the stroke of the engine is
bigger) and the engine itself. Actually you only need the blue Memcal
chip inside the ECM, but you might as well get the "Engine
Complete+ECM" as a kit from a local wrecking yard.
