Ok I've decided to start saving to put a turbo on my truck. My exhaust guy is gonna do the piping. I plan on putting the turbo behind the y-pipe along with the y-pipe mod. Wondering what size turbo I should run. Along with what size injectors etc etc. And I'm gonna need mike at 5 stars help for a custom tune. Its gonna be awhile til its done, but I'm not just blowing smoke, I'm gonna do it.(Sick of hearing my turbo diesel buddies saying how much power they have. Lol) any advice more than welcome.
Check my thread out in the excursion forum, I also have my kit up for sale in the market place. It made gobs of power, check the youtube videos out in my thread. I never had it dynoed, it picked my milage up as long as you can stay out of it to get the better milage LOL. get back with me. Mine was also tuned with an SCT product, I still have the tunes if 5star can use them for your truck. I highly recomment a MAF that works as blow through instead of the stock maf.
I tried looking for your post in the excursion section but couldn't find it. Any way you could post a link for me? Also does yours only run off the drivers side exhaust pipe?
Thanks!
I have a crossover pipe from the factory passenger side manifold to the custom header built for the drivers side. How much power are you looking to make? My turbo is good to about 650hp but at only 6lbs of boost the Ol V10 mages goobs of torque. I only ran mine at 10lb's of boost for a couple days just to see how it feels. I'm not sure if 5 star could view my tunes that I have in email and make them work for your pcm? you might contact them tomorrow. Let me know what you think after reading my build post.

LOL, my spool time was minimal. small exhaust housing and 415ci, I set mine up that way since I very seldom went over 4500 RPM. I would say I had max boost at 3200.
Power wise I'm not sure on numbers. I was shooting for around 6 lbs of boost. Its my daily driver so I gotta keep it reliable and keep the motor together.

This is the key for turbo sizing on this type application. Small housings and appropriately sized compressor wheels will make for a very strong truck for towing. If you can get it sized so that approx 70-80% of your peak boost level is at 2000 rpms,then you'll have one helluva strong towing engine. With 5-6 psi @ 2000 rpms-you should be able to town in OD just about any load you can legally pull behind the truck-in all but the most extreme hilly areas.

Ok so I'm looking for turbos. Got my eyes on a T3 turbo with 4" divided inlet. 2.5" outlet. 70 ar compressor trim. Am I looking in the right direction here?
Ò btw turboV10 great post. Your an inspiration to me. I sent you a pm also.
T3 is too small. I wouldn't go any smaller than a T4 with a 65mm turbine wheel or larger. You would end up with way too much backpressure, the .70 ar is right in the ballpark. Most of my GM LS1 buddies run a .96 ar but they turn to 7000rpm.
