What year 3.2 will just drop into the Cat? Any mods needed?

You have to use the 3.0 oil pan for sure, probably the intake manifold as well and possibly some of the accessories. But the block/heads are the same dimensions so it will go right in.

i thought the intake manifolds were the same? There is a thread on the swap somewhere.

I would think 2002-2004 3.2L out of a CTS would work...

They also had a 2.6 or 2.8 which is very similar and may work too but not sure on the details.

if you put in the 3.2 could you go with the 5spd too? or would the wiring for it be unrealistically hard to figure out?

Well I have talked to a few people and they all say, you need a clutch pedal assembly from a euro omega... then new master cylinder, cross member, custom drive shaft and perhaps a few custom switches so that the car doesn expect the "push brake to shift" sequence...

Aside from that I dont think there is much more to do...

Those dyno sheets with the 3.2 conversion site are odd. 165 RWHP for the 3.0 seems too low.

My stock 3.0L dyno'd at 185 RWHP. If I remember correctly CateraMV6 and another user on here also got 18x RWHP for their 3.0L cars.

With the 15% powertrain loss, that converts to ~210 hp at the crank, same as what the European 3.0L cars were rated at.

Remember, the 3.2L is a fly by wire engine. If your car is a '97-'98 you'll need all the throttle parts from the old engine including the short-nose plenum. In 1999 the Catera switched to FBW throttle so if the new engine doesn't come with the CTS FBW then the long-nose intake plenum and throttle servos can be carried over from the old 3.0L to the new 3.2L.

The funny thing about this article, is the two posts below, where two owners, claim to own a 2002 and 2003 model, both with tranny issues. Seriously, is this site for real? And what kinda consumer or car driver for that matter does not know the year their vehicle was manufactured? Unless they drive actual rebadged Omegas...

i thought the intake manifolds were the same? There is a thread on the swap somewhere.

Though the intake manifolds visually look the same between the 3.2 and 3.0 you will need to use the upper intake manifold from your 3.0L because there are subtle differences when it comes time to hook up your vacuum lines. As has already been said, if you have a 1997-1998 your intake manifold is cable-driven and is vastly different. In additon to all the things listed below that you'll have to change, you'll also need to change out your valve covers on 97 and 98 models because you use traditional plugs wires instead of the 99+ coil-on-plug design. Also, don't forget to change the flywheel out if your 3.2 engine comes with one already bolted on because those are different as well. As for accessories, when you put your old 3.0L beside of the 3.2L just make sure that you transfer everything from the 3.0L to make the 3.2L look like the 3.0L that came out. That will include the following:

Alternator,
power steering pump,
belt tensioner,
serpentine belt,
bracket that bolts onto the front of the engine by the power steering pump,
oil filter housing,
exhaust manifolds,
metal coolant pipe,
oil pressure sending unit,
oil pan,
engine lift brackets (one of them will have to change location or it will be blocked in the Catera application),
wiring harness,
upper intake manifold,
flywheel.
