Engine Swap

Currently, I have a 2.2L and I am wanting to swap it out with a V6 from another beretta. I have a 95 and the beretta that I am pulling it from is a 96. Are there any issues that I should be aware of before I make the swap. Any suggestions are welcome.:)

take everything from the donor car, as you will need it.

you will need to make you wireing harness obd2 because 95's are obd1.5

if your going to go through the trouble of a swap, find a 5 speed trans. the V6 is much better behind a manual versus the auto.

Well he can't use the harness at all anyways since it's a 2.2L harness. I have no idea if the dash harness on a 2.2L is the same as a v6 though so that may be another thing he should find/take from the donor to make things easier.

Definitely the instrument cluster, if either one has a tach, as a V-6 will cause a 4-cyl tach to read way off. Computer, wiring harness, transmission, CV axles, instruments, engine-mounts, radiator (should be thicker for the V-6), radiator and heater hoses if you don't want/can't afford new ones. Fuel pumps should be the same.

How exactly do you fixes tach issue and use the 2.2 interior harness with a V-6?

You just can't run a 2.2 or quad full cluster. The tach signal has to come from the ICM as my obdii fixes thread notes or you have to get a 96 cluster and it would be fine.

Tyler you should know that the tach signal runs through the engine harness for about 90‰ of it's run the last bit goes from the firewall bulkhead directly to the cluster.

But in all honesty I don't know if anything else is different. It may not be due to the fact that most of the interior stuff is the same.

And it would be easier for him because doing the 96 interior harness eliminates the harness fixes he would have to do to the OBDII engine harness.

^^^^^That.^^^^^In a =@ shell. :wink: Just saying that the cluster itself has to be swapped too for the tach to read correctly, if it has a tach.

Thanks everyone. Another question I have a choice between a 1996 3100 or a 1992 3.1 engine which one would be better for performance, speed, and upgrades?

3100.

Unfortunately, for what you are asking, the 3100 is the better choice. I tend to prefer the 3.1s, as I have had much better experience with their top-ends regarding reliability, but the 3100 has much more potential for power and more bolt-on upgrades available. If you do go with the newer engine, make sure you replace the LIMGs with a steel set, Fel-Pro and Dorman both make excellent gaskets for this to fix the otherwise chronic LIMG failures these engines can (notice I didn't say 'will') sustain due to GM's original use of plastic LIM Gaskets. Victor-Reinz also offers a set, but I have zero experience with their gaskets and they are pricier than the Dorman set. Plan ahead and buy them from Rock Auto and save yourself a bunch of money too...
