motor swap

[matthewauclair]

currently i have a 1987 s-10 pick up with a 2.2 four cylinder with a 5 speed manual and would like to know if there is any way to put a vortec 4.3 and a 4 speed automatic out of a 1999 s-10, i have the ecm and all the wiring for the motor and the tranny any help would be greatly appreciated

If you don't mind making it into your winter project it shouldn't be too hard.

Just take your time, and if you can keep the 4.3L parts truck around until your almost done it'll be easier, since you can still compair this, and that.
Plus you just know that you'll need something off it, if you don't have it right there

Painless wiring can probably make an adaptor for hooking the computer, and what not to your truck easily, with instructions.

do yourself a huge favor, and run a hurst style floor shifter instead of the steering columb swap. I think that it'll even go in the same hole in the floor, although I don't know for sure.

Good Luck, and Have fun

Unfortunatly painless won't do a harness for that type of conversion, and his ECM won't work with that motor. He will need the following



Engine harness
engine
body harness
transmission
BCM
ECM (you will have to have someone delete the airbags from the ECM)
Cluster
all needed sensors
cross referencing pin outs for additional rewiring.
frame mounts
motor mounts

Your better bet it to swap in a 92-95 CPI motor with a 92-94 ECM (though go with a 92 and you won't have to worry about setting things properly for a 4l60e)

im sorry my s-10 is 1997 with a 2.2 and yes I do have the e3cm and all the componets that will go into my truck to make the 4.3 work

Then you should just need to replace the ECM and the engine harness, transmission, motor mounts, frame mounts, drive shaft...
