I've been following this post as I am considering GSD as the shop to source and install a turbo on my 2018 6.2 High Country.  I am eager to see how your build turns out.  I contacted them as I was hoping to throw a whipple on my truck but James recommended a turbo kit and he said he's done 4 in the past year and I'm willing to be 2 of them are yours and the other guy's on here.  I am looking to see how these builds turned out before I dump the money into it.  I am only looking to get around 500 hp and James recommended a simple install and 7psi to get the power I want.  We haven't got into the nitty gritty details yet but this post is very informative so far.

They’ve had this dudes truck for a year. I’m no professional but that seems a little excessive. It’s been two weeks since the engine was put back in (again) and no update. Did it grenade something else?

Seems like a low expectation. My very first blower was a vortex. It gave 40-45 percent boost in horsepower. I would be expecting 150 boost with about 5psi with your starting horsepower. Or close anyway. I’m I missing something?

Maybe I should have worded it better.  GSD asked what power level I was hoping for.  I told him around 150 to the wheels extra is all I'm looking for and he suggested the turbo route.  We haven't dug deeper than that and have not discussed final numbers.  Keep in mind, just because my truck has a claimed 420 at the crank doesn't mean it has that.  Probably more like 340-350 at the wheels so bumping to 500 is a decent gain if you ask me. I am planning to hem out the details soon including what size turbo we will go for in case I want to dial up the power more in the future.  This is my daily driver so I'm not looking to do a lot of engine work at the current time.

I’ve driven many modified vehicles. The amount of mods isn’t what breaks a vehicle. It’s the right foot. My current boosted truck is going on 9 years after the most recent refresh. My very first vehicle in 40K miles had a transmission, rear end and clutch, it was stock. I read some post on here about modified vehicles by posters. It seems they’re always building never driving. I don’t care about being the fastest, I want to drive. You can only do so much on street tires anyway.

New 6.2's puts 380 rwhp and just over 400 rwhp with headers and a tune.  Then another 15 to 20 rwhp on E85.  Add a cam and heads and places like fasterporms made 475 on his wifes escalade with all of the above.

 

I would say your shooting low.

I drove one

 

new 6.2 is without a doubt slower than my bb tuned 6.2.

 

considering a k2xx 6.2 puts down about 330-340whp, and mine probably makes 350-60whp max, there is no way in hell the new one puts down 380

Eh, the mods fail and create unreliability. Maybe they last a few years. Even if you do a good job, hardly any aftermarket is oem reliable. 
 

also oem vehicles are designed to take the right foot all day long. Aftermarket can take the increased if you do it correctly. 95% fail on the heat management side. Egt’s, coolant, oil, trans, diffs, etc.

You are perfect candidate to slap on a tvs2300 and call it a day.

Do not go with this shop. They are inexperienced. It is 100% clear they are engineering this as they go along.

 

-Forgot headgaskets after boring the cylinders

-ruined the oem bearings at like 650-700whp (possible it wasn’t the shops fault, but unlikely)

-a truck with huge amounts of work space

-information on the platform, trans, and motors is extremely easy to source

 

it is still taking them an extremely long time to pull this off

The modifiers and pro performance builders are where car manufacturers get their expertise from. Otherwise they would build 100HP slugs and call it a day. I never lost an engine to modification. Even when it came to simple thing’s such as electric cooling fans, trans coolers or flowing intakes and heads. After market and builders have always shown the manufacturer how to do it right. Right now the aftermarket is making parts to put long life back into the engines that GM took out. Eliminating external vacuum pumps and cylinder deactivation.

Very very few aftermarket companies are capable of this.

 

I’m more talking about highly modified vehicles.

 

Example- highly unlikely any shop is building a 700hp jeep cherokee that is more reliable and can take the abuse as well as a trackhawk. You can outdo the oem in minor things but not full builds.

 

also things like eliminating afm has a sacrifice. Obviously gm is well aware more moving parts = less reliability. They decided the increased efficiency was worth it. That’s not really a good example of the aftermarket improving the oem. Most other examples of the aftermarket improving oem are spending more money to improve, and that’s not really outdoing them either since they are trying to build the car on a budget.

I rather build it than pay that kinda of money. If I broke it I’d have plenty of money to fix it with the money I saved. I was always happy with 100-200 HP over stock. The sensation of speed by unlocking the nannies is intoxicating starting at 400 HP. Until recently something as simple as good flowing exhaust had to be done aftermarket. In the seventies when I started exhaust alone unlocked decent HP for the time. The manufacturer usually had to be force into improvements and shown how.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?

      It's Been a Long Time...

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
