Engine Swap

[SoonerPmp83]

Hey Guys, i was wanting to know if anybody has swapped a 6.0 LQ9 into there 2000-2006 tahoe? Wanting to know what all is required and budget for that?

All of the Gen3 engines are essentially identical so it should be a direct plug-and-play swap. About the only real difference would be the throttle body (cable versus DBW) if you have a pre-'03 truck. There may be other small differences such as steam vent lines, emissions hoses and maybe injector plugs. But, between your stock setup and the LQ9, you should be able to drop it in and go once you have an LQ9 tune flashed in your PCM.

Ok so essentially I just need to buy the engine and swap over parts and get a tune. I have an 01 with cable throttle body so i might upgrade. I will assume the 4le60 will be alright with the 6.0. Its something i have wanted to do and I have 220k on my current 5.3. Thanks for the reply

Yes the 4l60e will be fine, it's what comes in the Denalis with 6.0's.

Sounds kinda crazy, it just might work though. Let us know what you find out. Open up a whole new ball game for us.

It's been done, there was a member recently who just did a 6.0 swap. I'll try to see if I can find a thread. He just swapped the 6.0 in and ran for a bit on his 5.3 tune until he got Blackbear to get him a 6.0 tune for his pcm. Everything off his old motor was a direct swap onto the 6.0 IIRC.

I'm working on a swap into my 03. Got an 05 6.0.

YES!!!

YES!!!

Lol. Was trying not to say anything until I was in the process or done, but I had a question about the 317 heads. Once the motor is in, gonna get a little more stuff done.

I picked up an '02 6.0L yesterday to rebuild and swap into my '01 Tahoe. There's some good information in this thread:

Great info there!

OP, lots of guys running 6ltr swaps here. It's not hard to do if you are mechanically inclined, shop quoted me $2k just for the swap, but I wanted to do more than just a straight swap so I did it all myself. Its a snowball effect if you start modding the motor lol.

I ran my 6.0 on the 5.3 tune for two weeks. The computer will compensate to a point. But if you start mashing the throttle it will lean it out and blow a hole in a piston. Same goes for extensive high was use. I drove mine two hours on the highway to the tuners. Took it easy and never had an issue. I also used everything off of the 5.3 and put on the 6.0. Use the 4l65 also. Direct fit no modification to anything during the swap.

6.0

Schweet! That should work well. I'm curious if it has EGR, hard to tell from this angle.

 

[Tonyrodz]

Not really sure. It's an 05. I haven't really had time to really drool over it yet!

Talked to my mechanic, he said there's no egr on it.

Yeah it would be on the passenger side manifold connecting to the intake. Its usually tuned out anyway.
