2002 chevy, 4.3 to 5.3 swap...

[zachs92]

here is the start to my swap thread. no pics yet but some info. pics soon to come, maybe tomorrow.

i bought a 2002 suburban, for a parts truck to make the install ez'r.
here is what in goin to use.
5.3
harness
computer
motor mounts
fuel lines
exhaust(unless i get LPP long tubes before the swap)
other stuff that i might need, this will be my first swap so i figured i waould buy a complete donor vehical just incase.

i might make another thread on swapping the complete LT interior over and to also to keep this a motor only thread.

Sounds like a solid plan. Can't go wrong with the entire vehicle in your backyard or garage. You should be able to take the entire "C1" and "C2" blocks or whichever ones you need out of the back of your original under hood junction block and "reinstall" the 5.3 "C"-blocks into the UJB on your truck, so as to not cut any factory wires for the 5.3 harness. Good luck!

Dig the HD hood.

Got any pics of the 92 swapped interior? (currently fiddling with 95 swap in my 91)

that will be an easy swap for you because you have the entire vehicle. A year or so back I did the 4.3 to 5.3 in my 2000 truck and it wasnt too bad, just didnt have everything

[zachs92]

im sure i will be hitting you up, was there anything that you had to do that was un expected.

ive hard that since im using the 5.3 computer than i need to install the steering colum out of the same vehical because of the anti-theift bs in the ignition. true or false??

i would just have the pcm tuned and have the vats turned off...much easier

hmmm will i have to take the pcm to the tuner before hand to get it tuned and get the vats turned off so i can even start the truck after the swap correct?

i was just planning on a dyno tune.


edit: i just called a tuner, he said to bring in my pcm and he will turn off the vats for $100

[banker099]

yep...vats has to be turned off before it will start
