3800 in a 96 beretta

[Chayes1988]

will a 3800 fit into a beretta z26

Probably but you will have alot of modding and fabricating to do.

Mostly on the bottom end I'm thinking.

[coddegt]

supercharged or non.
gotta watch that snout clearance
put heavier springs up front to compensate for the wheight
increase.
yeah its possible. with a little fabricating.
also that 4 banger has a different trans pattern.
you will need to use a v6 trans in order to fit.
many little things.
overall it is possible.

cool thanks I already have the 4T60E b/c it came with the 3100

Hey, what's up? I'm new to this forum. So, you seem to be in an odd situation. The 4T60E is more of a vacuum controlled transmission than most would like it to be. The 4T65E was offered in 97+ years, but some GM cars had them as early as 95. Also, The 4T60E, if it's the 94-95 version, is the 4T60E-HD version of the 92-93 transmission. That means you could pair it with a 91-93 supercharged 3800. The 3800 is an awesome engine, but it's too bad GM really messed things up. 87-93 were OBD 1 years, and then 94-95 were OBD 1.5, meaning that you had the OBD 2 connector but most wiring was experimental for the OBD 2 change. Your 4T60E has wiring available for either setup, but you would be able to use only the 170 HP NA 3800 or the 225 HP supercharged 3800. With an OBD 2 setup, you can go with a Series 2 supercharged 3800 engine.

The best way of going about this would be to get the OBD 2 PCM out of a car that had a Series 2 3800 with a 4T60E transmission. The supercharged versions of the 96 Riviera and Bonneville and the 97 Grand Prix GTP had that setup, so find one like that and try out some wire routing. The 96 to 97 years were also experimental for the PCM, but at least they were OBD 2. If you were to get a 98+ wiring harness, you would have a very modern wiring setup. However, you would then have a harder time figuring out the wiring to the transmission because the 4T65E was used from 98 to the present day.

All the Series 2 wiring is the same length, whether it's supercharged or NA. The difference is that the wire loom separates the wires into different areas. Whether you go with NA or some sort of forced induction, you should get the supercharged version's PCM to make it easier on yourself. The NA 3800s with a 4T60E got OBD 1.5 wiring, so you would have to go stock on the engine setup except for some porting and other things for which the OE tune can account. Overall, after all this writing, just know to look for a 96 supercharged Riviera or 96 Bonneville SSEi or 97 Grand Prix GTP wiring harness. It will hook right up and plug right in. If you go NA, you have to tune a bit or just download someone's HPT file. With a supercharged 3800, you will pretty much eat up your 4T60E after a while.

As for engine mounts: The Beretta had the 3400 available. Get the front mount for that and use a GM side torqe axis mount that will fit. That will bolt right up, but the issue is that it may not be secure. For the most part, it should be. See if you can get some solid mounts or ones filled with polyurethane caulk instead of rubber. Did the 3400 Berettas have engine mounts that reached out to the radiator support? Those would be good, but you would have to use a W-body 3800 mount set, which means using 3800 heads from a W-body as well. Not that much of a problem because the W-bodies are the Grand Prix, Regal, Impala, Monte Carlo, and a few others. Pretty straightforward, I think.

Well, that's all I've got until questions come up. A friend of mine and I are working on a 94 Cutlass Ciera 3800 swap, and it's pretty much the same thing as this. Check out 3800Pro.com Forum and MotorSwap. It's very informative. I recommend going NA because 205 base HP is actually pretty good for a Beretta. You can get some more power out of porting the LIM and exhaust manifolds. How much money do you have to put into this?
