I have a 03 gm 2500 hd 4x4. Was gonna procharge but ended up with turbo for a lot less. Still wanna keep a daily driver. Heads an cam are not to far form bein installed. What are your guys thoughts. Turbos are all new to me. Turbo specs

Gt4502. Divided housing.


Compressor:
.66 a/r ratio
69.5mm inducer
102mm exducer
Turbin:
1.33 a/r ratio
88mm inducer
90mm exducer

 

If those really are the turbo specs, I would leave the stock cam in the engine.

 

Just have it tuned an the heads later on

 

Need help findin a decent intake headers injectors etc....

 

Well youre fine with the stock intake, throttle body ect. Guys make 900 hp on the stock stuff. As for injectors seimens deka 80lb are a popular choice and are what I run. You said headers so this is going to be a rear mounted set up i assume? We need some more details on what youre trying to build here besides a daily driver, like hp goals, e85, intercooled?

 

Id like to keep it under the hood an run pump gas. I dont wanna have one hotside id like both manifolds to feed the turbo. Eventually ill run an intercooler. Im hopin to make mid to high 500s.

 

Look into the forum sponsers they sell hot side kits.
You don't need headers for a front mount kit.
from the sounds of it, you need to do lots of reading.
There's more than just bolt up and run. You need more fuel, control of spark (tune) and the turbo handles the air.
All of this works together to make reliable power.
500 should be easy, but non intercooled will make it tough.

 

Yeah just do some reading, from what you said I gathered you want a front mount set up but no log manifold?

 

Most of these log manifold setups are fed by both banks. Look into tricks kit. I'm very happy with it! And you don't need headers with these kits. Utilizes stock driver side manifold.
