Have a melling high flow pump

Engine is assembled and back in the truck. Time to button it all up, fill it with the break-in oil and start the process!

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.
