If it'* the 3300 to 3800.. it will fit... I know that for a fact because it has been done... ( witnessed it first hand ).. if it'* the engine swap you're tech is doing ... then I want as much info as you can get if possible... I know the hardest part ( other than having the money for all ths ) is to fabricate an extra frount engine mount.

L27 - 1990 - 1995 Engine, (3.8L), (SFI), V6, HO, 231 CID
As for the improvements part....I don't think so, at least not on the 92 that is! 93, yes it had improvements. The 92 was a backwards step for GM in my books. Making a EGR-less engine isn't great. I should know I've got one! Cracking Exhaust Manifolds & Burnt Exhaust Valves as "NORMAL" occurances is NOT an improvement!

I know the older Luminas had 3.1.. then they also went to 3.4... I wouldn't mind doing a swap that way.. but bigger is better.... 3.8 */C'd babey

I beg to differ, a little.... If I remember correctly the 92 SC Bonnie was using the old 3800 and it made 205 HP and 260 lb ft of torque... The NA engine had improvements, and was badged as the TPI 3800, in 93 the SC unit had some changes to help durability and power. So for 93 - 95 the 3800 SC made 55 more horses than the NA units..

1992 3800 TPI 170 HP 225 lb ft of torque..
3800 SC 205 HP 260 lb ft of torque

And as of 93 - 95 the SC 3800'* made 225 HP and 275 lb ft of torque..

Damn, been into Bonnvilles too longgggggg

In order for it to make 55 more horse, it would be the series II. Series II puts out 205 HP and the first car to see Series II were those 1995 Bonnevilles that it had it ordered as an option.
Edmunds made an error on this, too. Supercharged Series I was 225 HP 92-96. Then 96 I believe got the Series II SC.

Also, the first year to get the 3800 were SOME '88s. It was an ordered option. Other than that, they had the 3.8s that can in the '87, which was the first year of the FWD model. (not 86)

Ok, has anyone noticed the spacing difference between the driving lights on 95 bonnevilles? SSEi95, yours are close together like mine, but I've seen an SE and an SSE that are farther apart....Terminator, I think one was yours. Can anyone confirm? I'm just about wrapped up on the body styles, I'll be posting Engines tonight....then Trannies....and so on.

I thought Terminator had an SSE? His are farther apart. Crap. I'm probably all mixed up. Working out all the body differences is a pain. Hope the drivetrains go easier.

He does have an SSE ('95) but his lights are closer together. Check it out for yourself.

This is neat how things are done totally diffrent between Canada and the US when we are so close......

Your wright they did start using the 3800 SFI or what we call the TPI-Tunned Port Ijection 3800 in 1990, but that was buick and possibily Olds... The Bonneville didn't see this engine here in the US untill 92 when potiac changed the the larger and more areo dynamic body style.. And true there were a lot of these 92 egr defunked cars.... These were a problem... Notice how Will'* car has one, a 93 SSEi.... But through 91 the pontiac Bonneville had the 3800 EFI engine... But for 92 the SC 3800 only produced 205 hp and for 93 with the better 3800 SFI engine being used along with the improvements to the SC unit power was pushed to 225 HP... And remember I have a 91 Bonnie with an EGR valve and stiil got a burned valve, sounded like an exahust leak.. Its been a year now seince I fixed it and it still runs like hell.....

BTW thanks for that EPROM part # I finally got a new one a few hundred miles ago, and it runs better, shifts better, starts better, idles better, and my gas milage is where it was when I got her... These little chips can cause a lot hell
The Buick engine is different from the pontiac engine though. Timing components are where the difference is! Another example is the good old 350 CID! The Buick 350 was a 90 degree V8 with splayed heads while others were 60 degree V8'*, also 2 350'* were diesels too! The only reason GM went with an EGRless 3800 in 92 was that it passed Emissions without one! GM will NOT spend extra money if it doesn't have to, regardless of the outcome down the road!
