well since my engine is here and i'm collecting parts i figured i'd start a separate thread in here to document everything. there are other 5.3 swap threads but none on CK5 are done using a turnkey engine. if you look through most of them, a majority of the work is wiring, i dont have to worry about all that, ive a grand total of about 6 wires to hook up which includes A/C. i guess my thread will be more focused on the mechanical side of things, part numbers, etc....
so for those that havent seen my thread in the suburban section, here's my engine. it's a 2004 5.3l from BD Turnkey Engines in Reno NV. its got 78k miles on it and arrived to me complete with ECM, harness, engine cover to oil pan, flex plate to serpentine belt. it's DBW (drive by wire) and came with the pedal and TAC module. it also included the up stream O2 sensors for fuel mapping. Bryan at BD Turnkey, does away with the rear O2 sensors, MAF sensor and evap system in most cases. on my engine we decided to leave the pigtails for the smog equipment on and include a MAF sensor due to some smog issues a few other guys have had here in NV with engine swaps. the rear O2s, and evap are turned off in the ECM and the MAF sensor is only used as an intake air temp sensor since the engine is run in speed density rather than mass air tuning. chances are, i wont need any of the smog wiring left intact on my harness. but if for some reason i do, its there to use with a reflash of the ECM.

i'm using an AC Delco EP381 fuel pump and a WIX 33737 fuel filter. my engine does not have a return line from the fuel rails, it returns from the filter back to tank. i'm also using an engine oil cooler, the engine does not have ports for cooler lines so i'll be adding that myself. still need to research that a little and see whats needed.
