Gettin Parts Togather For My 6.0 Swap. Have Questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

HuntinNut · 02-26-2015, 07:40 PM

Finally got my 2002 LQ4 w/317 heads and have a few questions about parts before I start buying.

1. I'm looking for a LS1/LS6 style intake. If I buy a LS1 or LS Qualifier Intake do I just buy a fuel rail off ebay and use my injectors from my truck intake? Also I'm switching over to DBC so do I just buy the throttle body to switch it over?

2. My motor came without a harness. Can I use a harness from any 4.8/5.3 or 6.0 since I'm sending it off for stand alone anyway?

3. Same question for the ECM. Since Im sending it off does it have to be a 6.0 or will any LS ECM work?

4. What about the knock sensors, can I just swap to a flat valley pan without provisions to get rid of them?

I'm sure Ill have tons more questions as I go along and try to do my research, but I'm chomping at the bits to order parts and just don't want to make a mistake..

My Opinion:
Best strategy here is to ask whoever you plan to do the harness mod and PCM tuning.

The injectors will not work get some for the ls1/6 intake. The harness can be made to work but its gona cost more since it was dbc, and you want dbw, so all those wires and connector will have to be added. And injector connectors will need to be changed if harness came from truck. Also you need tac and petal assembly.
Get a harness from the setup you want to run, saves lots of money. Or order a standalone that you need.

I bought a stand alone harness from BP Automotive, it was less than buying a GM harness and having it redone and its a much nicer setup that a redone one. If you call BP Automotive they can help you out a lot and answer questions, plus they are a sponsor on this site.

I'm wanting DBC, not the DBW that I have now. That's why I wanted to know about the harness since all the DBW stuff wouldn't be used anyway.
