There is no 97 Bbody...

Thats about all I can add to this topic. Other than I have never seen or read anywhere about this being done.

Not to knock turbo Buicks or GN's or any of that whole scene. But, I can't imagine ANYBODY pulling out an LT-1, or any other V8 for that matter, in exchange for the Buick 6. I know not all B-Bodies are LT-1 cars and maybe somebody swapped a turbo6 in for a 305 - but I doubt it.
Don't take this wrong, I totally believe in them, I just don't think that they're very well suited for cars this big. They could probably even do a decent job, I just think they'd have to work too hard to do it. Just my .02

I did read in one of the car magazines late last year that a guy with a late 80'/early 90's RWD fleetwood did a Buick turbo 6 swap into it - reaplaced the 305/307 that came in the car.
If i remember right the car ran high 12's BUT was heavily modified because of the weight.

It's been done, sort of.

The Fleetwood is a Dcar, but the Dcar is really only a stretched-wheelbase Bcar, and they were built at the same factory. So with that in mind... see:

Thanks for all the great info.

BallSS Out,as far as, not imaging anyone getting rid of a 350/305 TBI or LT1 and transplanting a Buick turbo 6 in the car.Why not? I bought a 1989 Iroc NEW,w/a 5.7 TPI,did alot of bolt ons, no cat. and a gear change.The best it did was a [email protected],I got rid of that slow V8 in 1993 at 28,000 miles and had a Buick Turbo 6 put in and the very first time at the track it went [email protected] w/a 1.56 60' on M&H DOT slicks on stock rims/stock suspention.This was a used motor w/STOCK: turbo,inj.,tq,intercooler,cam and heads.It was in TURBO MAGAZINE twice in 1995 daily driven w/ac and 25 mpg. My 1980 Malibu SW has a all stock long block and it will run 11.60-50's.I only made 5 passes last time at the track,running a rich /conservitive tune.My last pass was a [email protected] w/my worst 60' of the day.The Malibu is 3,600 lbs. and I weighed my 1992 Olds CC at 4,580,but a Turbo six is 100 lbs. lighter then a Chevy v8.So thats 4,480 lbs.,it's the same as the Malibu filled w/6 passengers(still feels so much faster than that 5.7 TPI).
With all that said,I think the Olds will run mid-low 12's w/just bolt ons,like the Malibu run 11's w/just bolt ons.
Hope I didnt offend anyone,just when it comes to the V8's,been there done that and needed NOS to keep up w/the Buick's.

YES YES YES!!! Do it, please! I have been thinking about this swap for a LONG time. In fact, when I purchase my 91-92 project, that's the direction I'd like to take. I used to have an 87 Turbo-T WE-4 and I can attest to the power they can make. And if anyone thinks they are unsuited to heavy cars, they need to check out some dyno sheets. I was looking at a combo for a single turbo stock displacement,stock headed engine and it made 700 h.p. @ 5600 rpm and 750 ft. lbs. of torque @ 3200!!! Tell me that's not suited to a heavy car! It would pull easy low 11's in an SS. Turbo buick engines are low end torque monsters. And MEMPH1Z... have you ever looked into adapting a whipple screwcharger made for TBI trucks to your ride? I don't know what it would take, but I know they make them. Just an idea for ya.

Well here's the plan,my wifes 1992 Olds CC is really clean.White,gray ground effect,limo tint and keyless/remote start.We have owned it for 5 years now and w/well over 100,000 on it,the 305 TBI is a gas hog/slug!.I have replaced all the basics bushings,shocks,rotors,drum,springs etc.,but the lack of power makes me sick.I thought about a LT1 or even a built 383 TBI,but I have owned over 45 Turbo Buicks in the past 13 years and know the motor well. I have a complete running GN motor w/all the ac lines,rad. etc.,so I figure ,"stay w/what you know".
I was going to get Caspers Electronics,to make me a stand alone harness($599),use a TCI adaptor plate (700r4 to Buick motor)($100),new TQ 2,800 stall($299),walbro 340 pump ($150),fuel lines/filter,local muffler shop custom exhaust($2-300) and a posi.rear.
I have the GN frame brackets and motor mounts,but was unsure if the exsisting holes in the frame will line up w/the Gn bracket.Is the 1992 frame the same as 1978?Did some of the early Caprice come w/ Buick 231ci,the Malibu did .Or I will just have to fit it and dill new holes.

Sound fun?

Sounds VERY FUN!

PLEASE get step-by-step pictures of this transformation. If I ever buy my GF's mom's 92 Roadmaster, this is the direction I'd like to take with it.
