Silverbullet75's V8 Swap - 6.0L LQ4!

[SilverBullet75]

Hi All!

I've been doing tons of research for the last year+ on GM LS V8 engines for a swap into my VX. I've only seen people use the 5.3L so far. Well, I've taken the next step in my quest and just purchased a 2005 GM LQ4 6.0L engine with 4L80E automatic transmission. It has 60k miles on it, and is from a 2500HD truck. As of right now, my decision is to go 2WD (as is the current configuration of the transmission). But, in time I may change my mind. Note: The LQ4 was also used in the Hummer H2, and Yukon Denali.

I chose the LQ4 due to cost, reliability, durability, and mod potential. The 2005 LQ4 is rated at 325 hp (+/-) stock. With a cam swap and/or heads it will generate much more (add variables here). But, my goal is to run it stock for a while, then slowly increase the fun-factor.

My timeline and project plan is as follows:

Now thru end of year:
- Purchase engine/trans (Complete)
- Pay off the engine
- Clean-up, re-seal, replace external parts like water pump, main/rear seals
- Find a 1998-2001 Isuzu Trooper/Rodeo (or VX if price is right) with a bad engine
- Swap the VX's engine and/or drivetrain into the Trooper
- Use the Trooper as my daily driver.
- Sell Trooper's old engine or part it out cheaply
- Clean up the VX's engine/trans cavity
- Remove front wheel drivetrain of 4x4 (TBD)
- Insert LQ4 and transmission for mockup of mounts, etc.
- To be continued

I'll keep this thread going as I progress, and keep a running tally of pricing for those interested. Oh, and pics too!

I'm hoping to prove that this swap can be "affordable."
Autopros did the 5.3 build and projected a way high estimate for completion (IIRC: ~$40k).
I think this can be done way under $8k. Crossing fingers.

I'm doing the labor, BTW,This isn't my first rodeo.
The challenge for me will be the wiring.

So, with all that, here is the engine as it sits on my little Harbor Freight trailer in my garage.
