Did any 91 firebirds come stock with 3.8's?

 

also, i know they come with 3.1's but its labelled as a 3800, which is the same as my friend's 91 buick regal, and he says his is a 3.8. and the engine that's in the firebird is exceptionally clean and good running while showing 196,000 miles

 

nope, 3.1.

3100 is the fwd engine designation

 

so the 3800 is a 3.8...?

 

yep

 

No thirdgen ever came with a 3.8 except for 1555 1989 Turbo Trans Am's.....and if you had one of those, you would know it. 82-89 came with 2.8L and 90-92 came with 3.1. 93-95 4th gen's came with 3.4's and the California 95 Cars received the first 3.8L's. From 96+ all 4th Gen V6's came with 3.8's. 3800 is the designation for the 3.8.

 

my aunts 90 f bird is a V6, and she says its a 3.8L, she bought it used, maybe the previous owner did a swap, who knows. she says it has the 3800 badge on the back, so is it a 3.8?

 

Lets see a picture of the engine

I'll let you know....

 

I'm calling Bull****.

 

You sure your aunt doesn't drive a Buick???

What's with everybody claiming to have 3.8's in non-1989 thirdgens lately?

As stated elsewhere, PICS=PROOF.

 

If the engine points from the left side to the right. Its 3800
if it points from the windshield to the bumper. its a 3100
i highly doubt someone wasted money on making a non turbo 3800 fit into the car.
it costs just as much as a v8 practically.

 

dont know what past owners did to the car, hell, its got ss decals on it (after it got a recent cheapy maaco paint job, although it does look decent)

 

We all know what 3.8 came in the fbodys

Other than that it was a 2.8 or 3.1..PERIOD..

 

3800 Series 2 in the 95+ :finger:

 

I meant thirdgen bitch **** :double finger: :sillylol:

 

dont call on me now, just chalk it up to young stupidity, i know nothing of our cars, sorry, i'll figure it all out soon

 

Best of my knowledge:

3.1 = Series I motor. 3100 = Series II motor with better flowing aluminum heads and intake. Distributorless ignition and larger valves. (From the Grand Prix's. Regals and Cutlass' came with 3.1's)

3.8 = Series I motor. Found in 1980's Buick Regal T-Types and Grand Nationals. Distributorless ignition. (With attached Garrett TE44, 61, or 62 turbo charger)

3800 = Series II motor (L36). More aluminum parts and a counter-rotating balancer shaft. Intake faces rear of engine. Found in newer Regals, Grand Prix's, etc with the 3800 badging. (Although some newest models do not include badge) Can come equipped with factory Eaton M90 supercharger (L67), producing a minimum of 240HP, Weeeeeee!!!.

 

Just so you know none of those turbos are stock for a GN or TTA, by the way its worded makes it sound they are stock turbos, stock turbo is a T3, but a TE44 makes a damn good upgrade, as does a TA49

 

Oh, ****, that's right, the T3 was stock... It's been a while since I've played with the turbo cars... My bad.

 

3.8 & 3800 technically were different design. the 93 bonnie I had had the 3800 motor, later referred to as the 3800 series I, after the series II came out in 95

 

Ahh, so we throw a third 231 CID engine into the mix...

 

hows this from my 85-2000 Haynes Poncho, Buick, Oldmobubble book:

1985 3.8L has distributor
1986-88 3.8L TypeI has single coil w/6 posts (magnavox)
1986-88 3.8L Type II has 3 coil pack s w/2 posts per coil

86-88 motors have coil(s) on firewall side of engine

1989-91 3800 has single coil w/6 posts
coil pack in front pass side of motor

1992-94 3800 has 3 coil packs in front pass side of motor

technically, 89-94 motors are 3800 Series I

1995-Present 3800 Series II has 3 coil packs in front pass side of motor

 

I have a 3.8 in my 84 Camaro.

It was a swap in from a 82 Malibu.
