Ok here'* all of the differences:
L32 connecting rods are stronger than L67
L32 has GenV blower and L67 has GenIII
L32 is Drive-by-wire TB vs a mechanical TB on the L67
L32 is has a returnless fuel system and different injectors than L67
L32 may have larger valves than L67

Timing, firing order, etc should all be the same because an L67 programmed PCM can be used with an L32 as long as a mechanical TB is still used. Just putting the GenV blower on a S2 doesn't make it a S3 but the GenV is more efficient.

Your girlfriend'* sister is going to have the L26 motor. The L67 produces 240HP and the L26 produces 205HP. The Bonne may or may not be faster with the L67 due to the Bonne being heavier. A couple of quick mods could probably fix that though

I'm guessing a GT2 is something similar like the 2010 camaro 1 LT or 2 LT...and all the people who call it an LT1 camaro or LT2 camaro.. I wanna slap them and say.. "an LT1 camaro is a 4th gen camaro with the LT1 motor..you have a 1 LT camaro!"

correct

there in fact is such thing as a GT1 and GT2 grand prix for the 2004-2008 model. the badging on the car does not change but there are more standard options for a GT2 than an GT1. its the same with my alero which is a GL2 in the scheme of GX, GL1, GL2, GLS. and we have no exterior badges at all depicting these trim levels on our cars.

all I know about the series 3 is what has been said already about it. I am not a fan of the drive-by-wire because it feels more delayed and disconnected than a car with a traditional TB.

GT1 and GT2 aren't models though, they are option packs just like we have the in Bonneville and any other car for that matter. The point I'm making is, no one on GP forums calls them bay that ....that I've seen and I'm on a lot of forums. So when we are talking about a car and someone says a GT2 is a model.. that'* a new one to me.

I agree the GT2 is not a model of its own. it is a trim package that comes with the better options lke HUD, heated leather, N/A Gen III motor.

I was just wondering if i could get a Bonneville SLE with high end options also found on a SSEi without having to step up to a SSEI. because a SSEI will cost more than a fully loaded SLE.

I want a HUD, power sunroof, and a supercharged Gen III.

but i have heard from you guys that you cannot not get a supercharger on a SLE like you could on the 1992-1999 SSE'*. and did i hear from one of you that a Gen III 3800 isnt even available on a Bonneville?

All i want is a Bonneville with the options i want for around $7,000 with low miles, a low milage 2001 SSEI will be over the $7000 limit. BUT a fully loaded low milage SLE will be around that price. but i also want a supercharged 3800 so i am in a pickle.

anyof them with low miles will be over the $7,000 limit there is one here in NH that is a 2000 SSEi like mine but not as many options for $8,000 with 63k on it. but it will need work and no warranty

maybe cars are a little cheaper here or something. I have found several 2002 low milage SLE'* for around $7500.

I found a 2000 SE with a 3.1 for under $6000 but i wont buy a 3100 motor. i didnt know they made newer Bonnevilles with a 3.1

SHe got a good deal on her Grand Prix. $7200 for a 2004 with the GT2 package, every option, 60,000 miles

They didn't a 2000 SE has the 3.8

i figured it was a typo. or the owner has never popped the hood
