First of all, I'd like to say hello and how glad I am to have stumbled upon this fourm. It was a very unproductive day at work but I enjoyed reading as many threads that I did today. I have an oppertunity to (pending wife approval) purchase either a 1990 Bonneville SSE or a 1987 Lesabre T-type for under $300 each.

The Bonnie has 147k miles, white w/ gray leather, body & paint in good condition and claimed to only need a fuel filter to run.

I have less information on the T-type but understand that the drive train is no good but does have a recent paint job. Also it'* claimed to have the rare Grand National style interior in good shape.

Eventually, I would like to have the supercharged drive train in either of these two choices. I have seen a couple of websites that give details on the conversions yet I still remain a little apprehensive. Would one vehicle require less conversion work than another?

I have no clue, as I leave all technical speak to the guys , but welcome to the forums!!!

LOL ..Jeanie.... :P

Randman...welcome, unfortunately its not possible to supercharge an normally aspirated car, but the LN3 3800 powered SSE of that vintage is plenty powerful...

Thank you for the warm welcome, Jeanie.

Thanks for the link, Jim. I assumed that the supercharger could not simply be added to the normally aspirated motor (I tried to add a turbo to a non-turbo Mustang motor back in the day...what a mess). I was more concerned with the entire drive train. It would make sense that a L67 would be more at home in a Pontiac if that is where it came from but what about the Buick? Are the body styles similar enough to where equal ammounts of problems will be encountered? Should I just look for an SSEi?

Hey, welcome.

Adding a supercharger, even if it'* aftermarket can cause problems. The engines and trannys are designed for it. It would just cause problems in the long run.

Although, there is one member here who turbo'ed his old Bonnie.

If I were you, and I really wanted a supercharged car, SSEi is the way to go, or a Supercharged SE, they are rare though

In order to do a true SC swap you would need the engine itself, all the wiring, the harnesses and the proper tranmission. An SC'd car and a NA car are two different beasts entirely.

If you had the time, resources and will power, it can be done. In fact there was a fugly lookin Trofeo on Ebay with an L67 from a GTP...so..anything is possible. The question is..Is it worth it?

Welcome! By the way, you should get them both.

I like that! Buy both!

What he said ^^

Welcome aboard though...and if you're feeling adventurous try these;

http://www.l67swap.com

and

http://www.car-parts.com

If you're considering a supercharged engine then the most reasonable starting point is an L67. Do on search on carparts, you can find an engine, transaxle and halfshafts for under $2,000. You will need the complete engine wiring harness though along with the PCM (Power Control Module - aka the computer), you can also expect other wiring mods but check the swap site...it'* been done before.

Cheers,

Welcome aboard

hehe i say get em both, too! Good cars, both of em!
