      well i think it sicks the beretta 3.1mfi has 135hp while the cavi 3.1mfi has 140hp.
      you would think with the beretta weighing more than the cavi it should have the extra hp.....

        Depending on year the Beretta has a 3.1MPFI with 140hp/185tq. So it's all by year/ecm in my opinion.

          GM was also know to put different cam profiles in different vehicles. Like 1988GTU said in combination of cam, ECM, injector size, etc 5hp differnce is not a lot. You can pull that much just from a custom tune.

              That year didnt have the 140/185. If you do get it and you do have a few mod dollars to spend... Tune the car up (New proper plugs/wire, fuel filter, engine/trans mount, fluid change/check etc etc. Then build a nice TRUE CAI, have Ben burn you a chip, UDP & maybe 2.5" exhaust (downpipe back) if you have left over money.
              Now most people are going to say, "Why not just swap in a 3x00?" well for some people it's just that they dont want to and/or don't want to be like the other 10000000 Beretta owners that mod.

                hmm, yea i think 92 had the 140hp.

                between the ga 3100 and the beretta 3.1 it kinda feels the same.
                and when i had the 3100 it was hell getting parts becuase it had to be for that year.

                but for reason i'm really wanting to get one....
