Can I turbo my stock 2010 Tahoe 5.3L?

[chilleblanco36]

Just curious of what it takes to do this. I currently have a BB tune and that’s it. I’d love to have a low boost turbo kit.

nah, i forbid it

you can turbo anything with enough money and time. finding out if your engine is healthy enough for boost and how much its going to cost you is your first steps.

What’s going to be available in the budget after you install the turbo to deal with the domino effects of the weak links you’ll find?

Here’s a good article for starters...

My engine has 145k miles and has been maintained very well. Tranny services at 100k as it should. Truck is driven very mildly. I’ll be doing all the work myself. Just wondering if I had to delete the afm and all that before hand?

Me and my buddy build turbo mustangs all the time. Currently working on a twin turbo coyote in a 2005 Mustang GT. This is my first Chevy that I’ve owned for about 5 years now. My other Chevy is a 2007 C6Z.

Just unfamiliar territory for me with these 5.3L engines.

It's not the engine that you have to worry about. The stock bottom end is well-known to hold ~800HP all day long and plenty are hitting 1,000. I've never thought of it, but I'm betting you could keep AFM assuming it's in top working order. I'd shut it off in the tune, though. You're fortunate to have the 6L80. With careful trans tuning, I'm betting you could safely put 10 lbs. on it. If yours is FlexFuel, you won't need injectors if you run 93 octane E0-E10.

I’ve had the AFM disabled since day one after reading about it here. First I used the plug in to disable. Now it’s disabled in the tune.

I disagree on the injectors.

With H/C/I/E .........at 5900 rpm I was damn near 100% duty cycle on the OEM 38# flexfuel injectors(this was on a 93 octane); that was at 360 wheel on the dyno. I have since upgraded to the OEM 50# flexfuel injectors from an L96/6.0

 

[chilleblanco36]

Note taken. It appears after a test on all cylinders, possibly upgrade fuel pump, and upgrade injectors, I could run 10 psi or less. I’d be good with 6-8. No real reason for wanting to go boosted except for the cool factor and being different.

I think a whipple kit is a lot easier.....

If were going with the ease of installation, Procharger wins by a large margin. No wiring, splicing, oil or coolant lines needed.

 

[chilleblanco36]

Whichever is cheaper I’m in.

I accept this. Looked back over my napkin notes- 6 lbs is about the limit (mathematically) for FF injectors.

I was about to go down this route with my 5 3. It looks easy enough with the kits out there. Then you read stories about people nearly catching their ac lines on fire from the heat.

Unless its a project vehicle i wouldn't even consider it if it's a heavily used vehicle. But thats just me.

I ended up spending my cash on a 6.2 swap and i am very happy. 6.2 alone is 100 hp over a 5.3. Add headers small vvt cam and youre another 100 hp over that. More money but factory fit and reliability.

I was just gonna supercharge my 5.3 but it had high miles. Also reports of blowers obliterating MPG. I think id do a procharger since you can stay out of boost easier at low rpms and retain decent mpg.

With my 6.2, i tailored the shifts to shift at very low rpm with light pedal. It can get 14.5 in mixed drivinfmg this way. I couldn't do that with the 5.3.

You gained 100hp with a cam and headers on your 6.2l?

Any 6.2 will gain that easily. Ive built many 5.7, 6.0, and 6.2 engines. They all gain about that with headers cam and tuning.

 

[chilleblanco36]

What’s the average cost for a 6.2?

No idea the average. I found a 50k one shipped to my house for 3500 total. I spent around another 1000 on it with cam, lifters, gaskets. Of course scope creep sets in and I added stuff like a small converter and ed the heads. Its real fun to drive though.
