Twin turbos!

AceAdams11 · May 13, 2016

Okay to start in have an 02 denali xl. Have had it for a few months and love it. Has always been my dream truck. My parents picked it up at 65k and it has 211k now. Now for the fun.. I have an 87 jeep that's just sitting because I love Pam now. Named her after the chick from archer. Well a friend is going to trade me to Rayjay 60mm turbos for the jeep. Deal going through probably tomorrow. Denali is bone stock except exhaust. I was a mechanic so not dense here. 1 where can I find some good manifolds and piping kit? 2 safe boost level until I get into doing internal work? Intake manifold need to be changed? 3 AM I GONNA NUKE MY TRANS? Any help I will greatly appreciate. Happy to finally be part of the family!

1) Hi Google 2)I thought you were a mechanic 3) yes

AceAdams11 · May 20, 2016

I am a mechanic. However not much experience with turbos. Done all the research now. Was trying to streamline info but there seems to be little movement on this forum. Will post pics when it's finished

For manifolds, flip your stock ones. Boost levels are negligible. Plenty of people throwing 20+ to bone stock 5.3's and 6.0's with supporting fuel mods. 4l80 should hold a fair bit of power without any problems.

Google and Youtube will be your friend with this project.

Look at performancetrucks.net. plenty of guys running boosted engines and really pushing the limits. Given the size of your truck and potential power level I would jump to a 4l80 as they seem to be rather stout and can handle around 7-800hp with a shift kit and tune. A stock 4l80 is comparable to a very well built 4l60.

I'll loose my awd with the 4l80 right.. not a big deal but just curious. Thank you very much btw!

Fairly certain that the Denali's come factory with the 4l80.

dubyagee01 · May 22, 2016

I thought they had the 4l65e.

Only the 2500 series suvs had the 4l80 to my knowledge. My motor came with a 4l80, but it was in a 2500 suburban.

The 02 denali does have the 4L80.
You can also call a dealer (parts department) with your VIN.

If they did I would have ditched my truck a long time ago for one. Just not going to find one. I would love to have a 2wd Yukon Denali with a 4l80. If you find one post up..in the meantime for your reading pleasure..

All Denalis will come equipped with a heavy-duty four-speed automatic transmission called the 4L60-E HD. While not as big as the massive 4L80-E used in three-quarter- and 1-ton trucks, this beefed-up unit has numerous upgrades over the standard 4L60-E for towing and added durability behind the Denali-specific 6.0-liter powerplant.

Wow aren't you a smart guy. You sent me a link for a 2001. Maybe look at the proper year that I quoted.
Also here is a screenshot of the tech sheet for a 2002 YUKON Denali XL 1500. Note there is no mention of 4l6anything being an option for that year. I can also pull this off of alldata and mitchell.
Also when I just did a transmission service on my 2002 Yukon Denali Xl 1500 6.0L V8 AWD I definatly serviced a large ass 4L80 transmission, not the smaller 4L60.
Maybe use more reliable resources for your reading pleasure.

Hmm funny......no response. Smart guy.

Yeah I have a response. why is the OP worried about losing his AWD if going to a 4l80 if he already has one according to your data.

Crawl under his skirt and see for yourself. At the end of the say it doesn't change my shit either way. Congrats on your win.

Do me a favor and take a picture of this 4l80 on your truck. I just wanna see one to make me feel better about myself..consider yourself an educator of the not so smart.

The butthurt is real. I want to be here to help. Not argue.

adventurenali92 · May 24, 2016

Well i can't say whats in the 2002. Not sure on that. Although a client of my detailing business has a 2002 Denali XL and I've driven it several times helping him pick up cars. His 2002 has 231k on the clock and still has original factory trans. It's still going strong and it shifts like a boss. If his has the 4L80 TRANS that would explain why he hasn't had problems with it and it's such a beast. My 2006 Denali XL has the 4L65E trans. Had to be rebuilt a couple months ago at just 83,100 miles. I was pissed that my trans went so young. And he bragged that his is going strong. Ugh. Anyways can't say what your 2002 has but my 2006 has the 4L65E trans.

Wicked · May 24, 2016

Xl=4l80 non xl=????? No data to back that up. Just my first thought that comes to mind

AceAdams11 · May 25, 2016

Lol wow that escalated quickly.

Is this for 1500 or 2500?

4l80's only came behind the 2500 yukon xl, not to be confused with the yukon xl denali 1500 which had the 4l60/5e trans. It could have been swapped already. You can just look at the rpo code in the glove box or look at the trans. You can keep AWD with a 4l80 trans.

**edit** 2002-2003 yukon xl came with the 4l80 in them as an option, not the denali

and to the OP, hit up trick performance or kb systems for a kit. They're stuff is really popular and affordable. You can find them over at performancetrucks.net
