Just asking some questions to do some research. I found a 2004 5.3 w/ pcm and harness with 3,000 miles. I read the sticky, but what do I need for the swap? Can I use my tranny? Is the 2004 drive by wire? Where can I get the mount kit? What about wiring? I know these are somewhere in the sticky, but I have to ask. How long to do the swap? Do I have to cut and box the frame for the a/c? I know I am asking a lot, but at 175,000 miles on my old 5.7, I want to get busy with this.
if you had everything in hand or available I'd say you could do it easily in a week but since its your first time I would say to allow yourself two weeks, three weekends, to complete the conversion. It's not a difficult conversion, just time consuming. Check out the OBS to LS1 conversion page for a some of the things that you'll be addressing along the way.
im in the same boat, gettin ready to install a drive by wire LQ9, does not seem hard just time consuming but should be worh it. For adapters and wiring check hotrodlane.cc or nelson performance maybe even e bay
Thanks for the info. I'll check the pages. So, two weeks to do the conversion? There must be a lot of modification to this swap. I've installed several engines and swapped some imports for my daughter's boyfriend, but usually done in 3-4 days.
There are a lot of loose ends to accomplish on an OBS to LS conversion. If this truck is your primary mode of transportation, you will definately need an alternate means of getting around. What electric fans are you going with? Who's doing your computer & harness? What exhaust manifolds & exhaust system are you using? What intake air system will you fabricate? Will you be cutting & welding the frame for the stock A/C compressor use, or going with a top mounted passenger side Sanden 508 & bracket & pulleys from Street & Performance? Can you fabricate your own A/C hoses & fittings? Your driveshaft, will it need shortening, like mine did? How clean an installation are interested in? Will you be degreasing & painting the engine bay & forward frame before the install? What high-pressure fuel delivery system & filter will you be installing? Do you have the pin-outs for your donor engine & and transmission wiring info, so you know what to wire? What will you be doing with your ABS brakes function? Etc., etc., etc...Quote:

I will probably use Nelson for the wiring. I hear it's easier.As far as the A/C, I need to look at the price of the passenger side mounts and pulleys versus modding the frame. I don't know about the ABS, haven't gotten that far yet. I am open to suggestions to make this as painless as possible. I can park the truck to do the swap as I have another car to drive. I want to detail the engine bay while I have it empty. Do you have any pics of your swap I can look at to get an idea of placement? Thanks.
This setup works on 5.3? Anyone here tried this?Quote:
