Ive been looking at the kb racing turbos and what they offer. What extra stuff would you need for the kit to be complete and it says it offers the 40mm wastegate and the 50mm blowoff valve. Would it be smart to upgrade the 40mm wastegate to a 50mm or can i get away with the 40? Im planning on boosting my little 4.8 here soon and just need some help with getting the kit complete. Could i also get away with running low boost and having the stock injectors and stock transmission and in time when the funds come in swap the 4l60e to a 4l80e and beef up the injectors?

thank you

 

i'd recomend talking to kyle. he know's his kits best and has seen them perform on dozens of applications.

 

im in the same boat other then i swaped over to an 4l80e already, but i´ll install the turbo kit before i start with fuel upgrades, my plan is stay stock there and learn how to tune with low boost then i´ll upgrade fuel and up the boost, talk to kyle hes really helpfull and takes its time over the phone

 

He wont steer you wrong. I have had one of his kits with his help through recommendations, and I have over 50k miles on my motor with his kit and it goes through hell. I even drive it at -40 degrees below zero. I even still have the master power turbo on it, and it still runs low 12's on low boost.

Good Luck!

 

FYI the stock injectors are not going to allow you to do much at all.

 

what is Kyle's name on here?

 

i understand but seems like being at 7000ft above sea level, i dont need near as much fuel then you guys with the same combo (of course i dont make as much power) someone correct me if im wrong but i have alot less air here so i need alot less fuel

Let me know what I can do for you.


Also, even at altitude, you still need some bigger fuel injectors. At min, 36lbs flex fuel injectors or 43lbs 8.1 marine injectors. Stock injectors are only 24lbs and that's not really even enough for a healthy NA 6.0
