1991 C1500 TURBO 5.3/4L80E

I can. It's not gonna be anything crazy.
Just stock truck with pump, injectors, valve springs, and turbo.

I've ran 10psi at 2000 towing but it didn't stay there long. It would accelerate and then you would be back in vacuum
5-6psi is a sweet spot and engine will last forever if tuned right and good fuel.
I've got 500,000+ miles on the 6.0 now that I was beating on for years. It had nitrous, water/meth, and boost all at the same time for awhile.
Don't get greedy with timing and let the boost do the work for you.

Forgot bout this.
A friend wanted to turbo his truck so to help him out I sent him a video of boost every morning. Haha he said it was torture.

This is about 70% tps to keep it in 4th with TC locked. About 2100rpms

And on a 5.3 no less. What exhaust housing is that and what options are there?

Thats a 1.0 Housing. and i think for T4 you can go up to a 1.23? Im not exactly sure. but a call to Forced Inductions and they can pretty much put together whatever you want.

So after driving this truck for years it's time to change directions with it.
Pulling engine and trans out.
Putting a alum 416ci in it and debating on turbo on it or nitrous and a holley dominator to control everything with traction control and all that fun stuff.
Trans brake 4l80 with a better converter and sell as a fun daily driver.


The 5.3, turbo, and 4l80 in it now is going into my 2000 GMT800 truck that I started all this out in back in 2004 when turbos weren't as popular as they are now.

Found some DSS Racing pistons on sale today for a sweet price so it's going to be a 404CI since the pistons are 4.010".
823 Heads went to machine shop to get cleaned, surfaced and cnc port work.
Ordered a cam motion 232/242 .621/.604 114 cam today and some their new .670 spring kits.

just waiting on the K1 crank and K1 rods to get here.

I vote turbo, but it'll rip either way!
