More than that, the driveability of 500hp turbo is just like stock.
500hp NA is alot more of a PIA to drive. The turbo will also be better on gas.

New project: '00 S-10 ext. cab, ZQ8, 370, T-56, daily driver.
having 500 NA is cool dont get me wrong but having had an old school 406 i made 400 HP NA and it was a pain in the ass to drive on the street... you have to go to radical almost to get it accomplished. now gtting 500 HP with a turbo would be the way to go. easy on parts and you dont have to build as much of a radical motor... but hey 500 is 500 no matter how you get there... good luck keep us posted.

<div class='quotetop'>QUOTE(Jamest @ Jun 29 2006, 08:17 AM) [snapback]56630[/snapback]</div>O.K THIS IS WHAT YOU MAY NEED. I HAVE UPDATED WITH A NEW CAN SPRINGS METH KIT AND AN S/D TUNE BY ALLEN NELSON: 475.7 HP AND 521 TQ AT THE WHEELS.I RUN A STOCK LQ4 ON 10 PSI AND I THINK I AM IN THE HP RANGE AT THE CRANK. AT THE WHEELS IT WAS 340 HP 400 TQ AT ONLY 5.5 PSI. I HAVEN'T HAD IT DYNOED YET AT 10 PSI, BUT I CAN TELL YOU BY THE SEAT OF MY PANTS ITS A LOT FASTER. THE LQ4 IS A CHEAPER ROUTE JUST ADD STRONGER PISTONS AND A GOOD CAM AND YOUR GOOD TO GO.

Jamest what are you running for rotating assembly and pistons in that, that sounds beautiful, what is your compression ratio
Also James about how much would need to be invested to get a setup similar to yours.

Man this is an old thread?
O.k. I have a stock 6.0L, lower end. LQ4 The heads have been cleaned up and arp head studs. Comp cam with springs and hardened pushrods. and that is it. The motor is basically stock. It is still holding up well. I now have a Trick turbo system as where I used to have the STS. Both good systems.
I run 9.4 to one I think, or 9 to 1 I can't remember.
Oh yea, I have more HP and Tq now, and it still runs like a normal truck. I get over 400mls.to a tank on the highway!

thread revived, i'm building an lq4 at the moment but i'm going out on the preverbial limb. Mine will go like this:
03' 2500hd LQ4 stock shortblock
04' 5.3l 706 heads with stage II port and polish
trickflow dual spring kit with titanium retainers and seats
comp cams 220/222 .581''/.581'' 114LSA camshaft
GMPP open plenum manifold
AeroMotive fuel rails and regulator
8.1L injectors
88-95c/k radiator with oil cooler and transmission cooler (double row core)
OBX Lts with catless y-pipe
mine will be n/a and i still have no idea what kind of power it will make
but the lq4 is very versatile and respondes extremely well to boost, especially with a set of ls6 heads, you have to be extremely careful though because the ls6 heads will bump the compression way up and boosting could be tricky, but with the better flowing heads, you can gain alot of HP with the same boost

You can gain a lot more if you went with a bigger cam in that 6.0.

2005 GMC CCLB DRW 6.6 Duramax 4x4 191,000 and counting
2013 FORD CCSB F350 6.7 Powerstroke 4x4
always comes back to the cam, jeez, i gotta drive this thing to work each day and with the 5.3l heads, if i get too much cam and too much power, i'll end up with a truck that has the worst kind of street manners. i'm going for a scolded monkey, not the bat out of hell.
