Anything is possible. Just how much work are you going to have to put in is the question? Shaun and I have tossed this idea back and fourth for years now, and yeah its basically a PTO off the differential housing. That said it will be far less aggravation on an aggravating project to just start with the AWD 4t65, I mean you need the rest of the system anyhow may as well just start with getting all of it. Honestly just buy an entire donor car. You'll need it, i'm sure. also the Versatrak fluid is $33 a quart. The other question to ask is "what is the goal here" if its performance that system from what we found was far less of a "performance" oriented system and more of a "bad weather" system. you also have all the running gear out back to deal with as well as making it actually fit in a car that never had the provisions

Yes, you can swap in a 3400 LA1 where an LH0 (your 3.1 MPFI) resides. From my understanding, the 3400 is a bored out version of a 3100 (L82), itself an updated LH0 with SFI and other minor improvements. Your real issue will be that you may have to convert to OBD2 or send your computer out to WOT Tech or Milzy Motorsports to get the computer programmed to run the LA1. That would eliminate the probability of issues with the new engine. What most guys have done here however is swapped out the 60 Degree V6 (the 2.8, 3.1, 3.4, 3100, 3400, 3500 engine family) for a Buick 3800 S2. You could go supercharged or keep it naturally aspirated, however this would be the easiest thing to do as the 1996 Buick Regal and 1998/1999 Chevy Monte Carlo both had a 3800, but in naturally aspirated form. In theory, you could get a donor 96 Regal and convert your 93 to OBD2, and 3800 power it along with the transmission since the 3.1/3100 had the lowest gear ratio of the 3 engines available. The LQ1 had the highest ratio at 3.42 and I think the 3.1 had it at 3.30 or something along those lines. There's a lot of threads of people swapping a 3800 in their 1st gen cars on here.

well, about the only thing you can do to a 4T60 from a N/A car is rebuild it with parts from a 4T60 out of a turbo grand prix. The 4T60 in the turbo grand prix is the same as in 2.8 and 3.1L N/A cars, just a lot beefier, like better valve body and torque converter for example. There is a shift kit on top of that, I think, but it can only be installed during a rebuild, from what I have heard. While you got the motor apart, get a crank from a 3.1L, cuz a 3.1L is simply a stroked 2.8L. I would get the 3.1L crank because of the torque gain you will see. The 4th gear on the 4T60 is very weak, but I dont think you'll be doin high speed runs in a dune buggy. If you rebuild the 4T60 with parts from a 4T60 out of a turbo grand prix it will hold 210-220HP. The stock trubo grand prixs had like 205HP and 225lb/ft which was limited. Just rebiuld with those parts and you should be good. Good Luck!!! Welcome to the board Robby
