Default Who likes what intake manifold for turbos?

Have a 5.3 and it came with the truck intake. Some people say its ok to use and others like the ls2 intake for the bigger throttle body. Also what about the aftermarket,. Holley tunnel, fast etc. Thanks

Been discussed 1000 times. If your planning on 1000 or less any OEM intake will work great. Truck intake works great.

Thanks. Looking at 700 to maybe 900ish hp. Someone told me that over 12 pounds of boost the stock intake cracks.

It here are a few people on this board running 20+psi and 8second in the 1/4 mile with stock truck intakes, LS1 intakes etc... I'm using the TBSS intake on my 6.0/S475 build shooting for 850+rwhp!

I've been running stock intakes on ls engines with boost for years no issue. Truck intake is my choice.

Stock 48 runs a stock 6.0 at 23lbs of boost with a stock truck intake and runs low 8's in the quarter on a daily driven Nova. I am not 100 percent sure about the specs but it's pretty close. He has proven the truck intake works great. They just look like ****. lol

Yup they look sh$t but they work. ls6 would be my next choice . I like the holley intakes also if you got money to spend. Also look at denmah's builds he also uses stock intakes with no problems.

Google "shaved" ls manifold. Some of them look great over on the truck forums imo.

Thank you everyone for your input. I like the holley but its $$$$$$. I have a ls2 one on my 6.0. This 5.3 im going to leave the stock tahoe one on. Just got to figure out what turbo to get. Any ideas for a single. Stock 5.3 for now but its going to get gone threw with all the upgrades to handle 800 to 1000hp. I heard the 76mm with .96ar will be good. Tubrnetics 76-75 or percision turbo. Cx racin or on3? Any imput
