02 denali 6.0 w/dbw throttle. This is the lq4 engine with lower compression from what I understand.

Going with a custom twin turbo setup, currently gathering parts (fmic, manifolds, flanges, efans, piping, etc.). Been trying to do some research on common mods. I've seen the writeups showing what it takes to do the ls6 style intake swap, though I'm still a bit fuzzy on throttle body compatibility since I have DBW.

Anyway, it's unclear whether I should do a cam/intake swap, or just leave it alone and run the turbos on the stock motor. I've read the z06 cam/springs are a popular setup, as well as the ls6 intake swap.

I am also kinda pondering on a head swap. Not because I need the power, but because my truck came from up north and ALL of the header-to-head bolts are solid rust. In fact one is already broken off. I am sure that I will break off more if I attempt to remove my stock headers (necessary when I do the turbo setup). So, odds are the heads will need to come off due to broken studs, and I figured perhaps I could turn the situation to my advantage. Any heads recommended? Remember I do not want to increase compression at all...if anything I wouldnt mind lowering it a few tenths of a point.

I dont mind doing the work and putting the money into the truck (look at my sig) but I hate doing mods that have little to no real world benefit. IS this **** really worth fooling with, or should I just leave my stock cam and truck intake in place and be happy with the 6-10psi I plan to run on the turbos? Same with the heads...swap them, or pick up a set of stock 317 castings and bolt them back on?

Truck is a daily driver and must remain fairly smooth and tame, though I have no problem with a little bit of a lope at idle as long as idle is strong and doesnt surge. I'm not looking to rev to 6700rpm either, but 6000 with a strong top end would be nice. I know it falls off above 4800 or so right now.

Throw me some opinions people. Thanks in advance.

 

Vic Jr. intake with intakeelbows.com upper 90*. It works good......

 

Does it work 1000 bucks good though, that is the question?

 

I went lean on the number 7 cylinder because of the intake i was running (stock) The vic forced equal amounts of air into each hole, thus no lean spots.

So yes it is worth it. Safer, more power, and looks
