I just bought a 2004 Chevy RCSB 4.8 with the sole purpose to turbo. I am home 14 days of the month and will only be driving it once in awhile on the 2 weekends a months that I'm home. I'm looking for an aggressive 4.8 turbo/cam setup. Needs to be streetable but this is far from a daily driver. Only see about 3,000 miles a year. I am not sure on the turbo or cam. I will most likely be using an on3 turbo just to get me going until I can narrow down the turbo to use. I will be running 10 psi for normal cruising and 16 psi for business. Looking for a fun street truck just to raise hell.
Will be burning 93 pump gas NO E85.
Looking to order the kit and parts as soon I lock in a combination. Any first hand help would be nice!

Here is what I'm thinking so far:

-PURCHASED-
-KB hotside w/ s475.
-EPS Custom Cam.

Any help would be greatly appreciated. And yes I have been using the search button... Since I joined in 2006.....

 

Clean for a 2004.

 

here's two i have links saved for (was thinking of maybe one for my 5.3 turbo build i will eventually be doing)... not sure how well they will work with your combo you are wanting (or mine im planning).

Speed Inc - Speed Inc TU1.5 Turbo Cam 228/228

Tick Performance Blower Stage 1 V2 Camshaft for LS1 & LS6 Engines - Tick Performance, Inc.

 

Man, I thought for sure I would get some feedback with a couple hundred hits... Well I'm going to order turbo kit Monday. Going to call Geoff at EPS to spec cam & circle D to spec TC.i'll probably go with dual 255s pumps. 80 lb injectors just not sure what brand. Ordered electric fans. So hopefully I will have everything lined out and ordered by next week. Also going to swap to better turbo after I get a few miles on the setup and get all the bugs lined out.

As always any help would be appreciated.

 

Stock48 triple 12 cam and the on3 78/75...should get the 4.8 to 700 club.

 

Honestly, you should just copy my set up. This thing is a beast at 12psi. I love my borg unit and would recommend it for you. Also, the cam you have up there is going to make for a real dog down low which isn't what you will want with a 4.8L. Run a small cam to get that toque down low and then let the turbo do its job up top. It will make for a much better driver.

 

Oakley6575, thanks for the cam/ turbo advice. I will get the smaller cam and on3 76mm then upgrade the turbo to the BW after I get some run time. I'm really amped to be pulling the trigger on everything. Just want to make sure I'm doing it right. Not new to the 4.8/5.3 but this will be my first boosted ride!! Do you have any dyno numbers at different psi levels? Just wondering about what I would be putting down with your setup. I'm sure 10 psi will put a smile on my face or normal driving!!

 

Speed inc TU0 cam will be great for your build. The 76mm on3 will be great to start, but I am also a big fan of BW long term.

 

Well, got a EPS custom cam spec'd today. Calling to order turbo kit tomorrow morning. Going with a 70mm for quicker spool and solid power curve. Should be fun to drive!!

 

Turbo kit ordered!!
