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.

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.

Well...here is what my take on the subject is: Why not?

I have an '81 Buick LeSabre Turbo Coupe Limited Edition. That's a two-door B-Body. Same as the old "box" Caprice / Olds. This car could haul ass when I wanted it to, yet would only sip the gas in town or at normal highway speeds. It was mated to a 200-4R.

Actually, I just pulled the engine out recently, as it was time to retire the car. Still have the tranny (plus another stock '85 200-4R from a wagon, and an Olds Hurst 200-4R fully massaged tranny to go along with it). You'd need the harness and computer from the old car. May be a bit of a problem tying it all together electronically if you want to stay with ABS, reluctors etc.

"You'd need the harness and computer from the old car. May be a bit of a problem tying it all together electronically if you want to stay with ABS, reluctors etc."

The stand alone harness,made custom by Casper Electronics,is a three wire hook up,w/provisions for TCC,AC,SPEED SENSOR etc. and plug in the ECM.($599)

"Early 80s caddy fleetwoods had v6 buicks in them Well. some of them did. They should work fine."

Is that a yes ,for the frame bracket holes?

Thanks again!

Like I said - I wasn't knocking them. My Buick 6 experience hasn't been that great. I drove an 87 GN about a year ago that didn't really dazzle me based on the seat of the pants feel. Maybe because it was bone stock and quiet and the power from the turbo didn't seem to be right NOW - and maybe that car was a turd, too. It seems that as I followed this thread I'm learning more about the potential of this motor. Being from "The Buick City" - you'd think I'd have known better in the first place, but I grew up as a Chevy guy. I also just figured that with 2 tons to move, like they say "there's no replacement for displacement".
Everyone knows the 305 is a turd (go ahead and flame me - it is!) so if you can make your wagon rock with a 6 - I think that'd be a bad ass build up to watch.
Good luck dude.

Motor mount time!

I have a question for you guys.

1984 Caprice could be ordered w/a Buick 3.8,I looked at the motor mount for one and it is the same part # as the 1987 turbo 3.8
I can get the FRAME mounts from a 1984, but the question is-Will they bolt to the 1992 Olds CC frame.Is the frame/engine craddle,the same in 1992 as it was in 1984 or did GM change it for the 1991-96 B-bodies?

Not for nothing, but...

Instead of putting in a whole new motor and electronics, wouldn't it be more efficient to simply turbocharge the existing LT1?

It's a 1992,no LT1. It's a hurting 305 TBI.

The wireing is real simple,the Caspers stand alone harness is a three wire hook up!I got the motor for free and have done alot of motor rebuilds/installs on GN's/TTYPE's
