Lq4 turbo questions

[Vance826]

I have a 07 (Classic) 2500hd lq4 and I have been looking at some turbo set ups and kits for a while now. I have some questions though. I like this kit alot https://www.speed-engineering.com/ls-turbo-parts/twin-turbo-kits/silverado-sierra/silverado-sierra-twin-turbo-kit-1999-06-4-8l-5-3l-6-0l.html

- They stated a 224 cam gave them 495rwhp. Can I throw in a ls3, ls6, or ls9 cam in to expect similar gains or would it be major loss?

- After cam where are we with fuel? What kind of fuel rails should I run and from where?

- I understand the truck intake is good, but what is a better option?

-What heads should I run? I keep seeing 243 heads are a good idea considering my dished pistons.

- I know a torque converter will meed to come in at some point. What do yall suggest?

- Anything else I should buy or pay attention to?

 

My truck is my DD and I can run e85 when the time comes. I am looking for some low end torque rather than hp. Thanks

If you run turbo, you'll be running higher compression. You'll probably need to change your hg and higher torque on the headbolts

I would go with something that has been tested and proven... Turbos are wonderful boosters.. I would go with something that has a solid warranty behind it.

- E1840P camshaft

- Walbro 400 w/ 60lb injectors

- Stock 317 heads, pac 1218 style springs. Get a 4 corner steam pipe setup

- call Circle D and see what they say about a converter
