Doing LS Swap - I have no idea what I'm doing!

[jjzepplin]

I just bought a 6.0L LQ9 for $375. I cringe when I have to spend that much on a fuel pump or tank. There has to be a cheaper way. I am leaning into using a stock fuel pump but retro fitting into my existing tank.

I just finished my first LS swap. My plan was to keep it as simple as possible. Insurance auctions are a good source. I got an 08 Tahoe 5.3 that had only 69000km on it. On the down side it was a 4wd so I couldn't use the tranny but was able to straight swap it for a 2wd tranny at a wrecker. If you're watching insurance auctions if you look for a van or work truck it will have a 2wd tranny. I also bid (but lost) on a few Escalades for the 6.2 which would be a good score.

It's good to get all you can from one vehicle. That eliminates the risk of getting something not compatible. I got the engine wiring harness and ECM and TCM as well as gas pedal. I got battery cables and megafuse and power cables to starter/alternator. I labelled the plugs on the wiring harness as to where they go if it wasn't obvious. I sent the harness to a guy who reworked it (thinned out unnecessary wires) and he terminated the end with necessary relays and fuses so I just had to hook it up. I sent the ECM/TCM off to be reprogrammed to remove VATS, etc.

I splurged on a Dakota Digital dash and BIM module. It was expensive but it just plugs into the OBD II outlet but it saves a lot of other hassles.

Here are snapshots from a post I read on facebook. I think I am going to go this route on my swap.

Had a friend do this years ago, the noise was terrible! You couldn't put enough insulation on the tank to not hear it even with the truck running. But if you are fine with that, it will work.
