Chevy Beretta 3100

I have a 1996 Chevy Beretta z-26 3100 and I am wondering what the difference is between this engine and a 3.1 engine.

I am also wondering what engine would fit this car if I did an engine swap without too much of a problem. I would prefer something with a supercharger.

Any information would be greatly appreciated.

Thank you,
Dale

the 3.1 and the 3100 are the same engine and if ur lookin to do an engine swap you can easilly put in a 3.4L or 3400 as gm calls it with minimal work

now if ur lookin to do s/c then what u need to do is look for a company like vortech who makes many s/c kits to put on the 3.4( this makes the most sence to me) also gm s/c engine i believe u'll have to go all the way to 3.8 or 3800 (i've heard of one place in canada which does this swap on berettas i'm not sure on the price but i think it'll run about $10k normally aspirated)(check out beretta.net) but seriously consider getting a 3.4 and possibly boring it out for the larger displacement and if u still need more go to a s/c kit!! to put 10k into a car thats maybe just worth that is silly

but think about it cuz i was for a long time and then reality kicks in and i see the "$" figure

I've seen a 3800 SC swapped into a Grand Am (same difference).
It is, however a big project.
If you've done a chip, K&N filter, and a cat back exhaust your 3100 should be quick. Make sure all of your motor and trans mounts are in good shape and then do some suspension work to get that power to the ground!

WRONG! :disappoin The 3.1 and the 3100 ARE NOT the same engine. First of all, the electrical/computer system for the 3.1 is ODB, while the 3100 is ODBII. Those are not compatible. The 3100 has different heads, manifolds (both exhaust & intake), throttle body, PS pump...and the list goes on. The 3100 also has a roller valvetrain and cam, while the 3.l has a flat tappet cam and a non-roller valvetrain.

Also, the 3.4 and 3400 ARE NOT the same engine. The 3.4 (LQ1) is a 60* dual overhead cam motor found in Grand Prix GTPs from 91-96. The 3400 is a standard push-rod V6 motor based on the 3100. It is found in late model Impalas, chevy mini-vans, and grand ams.

And one final note...the L67 (supercharged 3800) would be your best bet if you were going for a supercharged motor.

If your comparing a 3100 Pontiac engine with a 3.1 Multi-Port Chevy engine, they are different.. but.. "3.1" and "3100" mean the same thing.

no.
A pontiac 3100 and chevy 3100 are the same, and pontiac 3.1 MPFI and chevy 3.1 MPFI are the same The are differences between the 3.1 MPFI and the 3100, such as improved heads and intake plenum.

yeah, i was just trying to say, that you can refer to either engine as 3.1 or 3100.. because both 3.1 & 3100 mean the same thing, has nothing to do with anything automotive.

the 3.1 and 3100 have the same displacement, but they are not the same engine

yes, well aware as i've stated. i could call the 3.1mfi a "3100" and still be correct, as i can call a "3100" a 3.1. It means the same thing.

it doesnt mean the same thing.
you can call a 3100 a 3.1, as it has a displacement of 3.1 liters, but you can't call the 3.1 a 3100

3.1 MEANS 3100... just a different way of saying it. it has NOTHING to do with automotive, or motors, or chevrolet. it is plain and simple math & numbers.

Swap for the 3800SC. Shop around, buy the engine and ECU's for about $1500, and swap it yourself. You can't beat nearly horsepower in the high 200's for that cheap, especially a car like that. OR, you can do what this guy said and bolt a super onto a 3.4L, which would cost more, and give less power.... but hey it's really personal preference, right?

looking for a blown swap? try the new 4.4 cad v8. it'll bolt in, more or less, as chevy engineers demo; if you can drop the 3.1, you should be able to stuff in the 4.4 without major surgery. or you could try a 305, 350, or 5.3. i'd mate it to a th-125c or cad fwd tranny.

better stick to that math major buddy.... you can spit out math numbers and equations till you r blue in the face, they still aren't the same engine. the blocks i believe are quite similar and will bolt up to the same tranny's, but are quite different in many other aspects.
