01 Tahoe turbo So im new here and have studied out this idea so much my head feels like its about to explode.
What i have: 2001 Tahoe 4x4 100% stock drivetrain
What i want: 550-600hp Tahoe sleeper.
I want to do this as cheap as possible at first and then slowly add better parts. Im not a turbo genius i have basic knowledge from working on my duramax, but thats it. I would like to start out with pretty much an ebay turbo setup, and fab my own hotside piping. With 80# injectors 340lph walbro pump, 4l80e conversion (after i burn up my 60e) and an ls6 cam. If the china turbo decides to explodes then i'll upgrade.
My biggest questions are, what turbo size? is there anyway i can keep my a/c? a cheap electric fan conversion? Who does tuning and how much is it? and just any and all advice you could give me.
Thank you in advance and God bless.

For a turbo I would go with a 69mm gt45. There the best budget turbo you can buy if to have the space. As far as retaining your Ac that's totally up to you as to how you route your hot and cold side piping. But yes it can and has been done. If it was me I would buy a trick performance log manifold as it would greatly simplify the hotside. Tuning your gonna have to get in touch with someone local to you and see about pricing

Thanks for the quick reply, that's one of the turbos I had in mind. As for the hot side piping for $1600 I think I'd rather try my redneck fab skills out and give it a shot. I guess I could do without a/c I never use it but it's just one of those things.
Search google images. You can easily retain a/c and run a 4" downpipe for future growth.
I'm picking up an '03 Tahoe later this month with basically the same running gear. When doing the 4L80e swap make sure to upgrade the input shaft in the Tcase to the heavier duty one.
A 2500 series driveshaft is much beefier and needs a 1350 pinion yoke to work. The front part would need to be shortened as well.

That was the 2nd turbo on my list. I had no idea it was smaller, I guess I need to study it more. But I just think a boosted Tahoe would be the coolest toy around town.

What do you guys think about this turbo? With the fuel im planning on throwing to it, using truck manifolds, what rmp range would you think would put me around 10psi?

Here is a link to check for sizing of some turbos, I am pretty sure someone had the 7875 next to a gt45 69 deal if you search it, and the gt45 is 300 bucks right now.

What fuel? 600HP is a tad easier on E85 vs gas unless you run a water/alchy system. A stock 5.3 will need about 2-2.2:1 pressure ratio to make that power.
A bigger compressor isn't always better if the motor can't flow the air at the right pressure ratio. Don't go comparing a completely stock 5.3 to one with cam/ heads, etc & running 25-30psi if that's not what you intend to do with it.
An S369 would work nicely. If looking at $500 turbo from VS then a S369 isn't that much more. Few hundred bucks.
I'd be Leary of the ones you are actually getting shipped to you on a boat. You can usually find the same turbo already in the states from a supplier that might actually stand behind it if it craps out 48hrs after you instal it. Don't laugh, I've seen it happen. You order that one from China, wait 2wks for it to show up then it craps out you are just out the money & time.

I've used one similar to this turbo before on a stock 5.3. 72mm inducer is a good balance for low to mid manifold pressures. Appears to have a wheel like a Q-trim in a .81A/R. It should spool nicely & hold power up top.

i knew that much, but the 4l60e i have is still under warranty from the last owner. So me being a carless 21 year old thought i would blow it up, have it rebuilt and sell it having 0 miles on a jasper rebuild. Then use that money towards my 4l80e.

Old designation for T4 turbine wheels.
Trim..........Exd.......Ind
O Trim - - 2.296" 2.922"
T4 P Trim - - 2.544" 2.922"
T4 Q Trim - - 2.693" 3.111"
I think it would be a pretty decent combo for the power you want to make, in a usable RPM range. Running a p-trim in a .96 feels pretty close to the same, all else being equal, to a Q-trim in a .81. Q-trim is a tad larger & flows a bit more. That turbine combo is good for 700-750HP & should spool by 3,500 & rev nice to 6,000+.
You didn't mention it but I gathered it will have a stock converter? That necessitates a little tighter A/R for a given wheel flow to augment the response to be a tad lower in RPM.
The LS6 cam will help on the top end but it loses a little torque down low compared to the stocker so that effects spool as well.
How you tune it will impact it's response also..

This one?
It uses a P-trim turbine it appears by the specs they list. So does their 7675.
