Is it possible to put a 94 beretta v6 into a 94 Chevy beretta that current has a v4?

Yes, it is possible, the only problem you could run into is the v6 runs hotter than the 4 cylinder, so your car will read hot as hell, when it really is not, (ive seen it done) you may want to check up on whether the mounts are in the same place tho as it is a bigger engine... = ? = I'm not sure on this but I'm pretty sure you would have to redo the wiring. Like the 4 would have a certain wiring and the 6 would need a different wiring. as for size I belive you would have to cahnge motor mounts or something It's possible but you have to redo the wiring, change the motor mounts, and theres probably other crap that I don't know. ? Yes it is possible. all inline 4 cylinder and 60 degree gm blocks have the same transmission bolt pattern. I just got done converting my Fiero 2.5 with a 2.8 v6 from a beretta. the only problems that u are going to face is mounting and a wire harness/computer. Since the Beretta comes standard with a v6 a junk yard is a good place to find the mount u need and also a wire harness. Everything must also come with the new v6, like fuel pump map sensor map regulator maf sensor fuel pump relay and regulator, and lots of other good useless stuff that they put on newer cars. Good Luck!!
