your 6 liter with 317 heads a LS6 cam with the sts kit
No way would i go N/A if i already had a turbo kit

 

Really ??? I thought about that cam hard mine!!

 

02-04 LS6 cam is well proven cheap boost cam
Sell all that other stuff and recoop some cash
lownslo06-chris.... has the setup i recommended to you but he has a front mount kit...truck runs damn good

 

Ok thank for info I'm thinkn about breakn down trying to do a front mount.

 

trick stage 1 front mount is $2000
but it doesnt include a intercooler or injectors
your rear mount has potential just need to get a bigger turbo
I would just upgraded turbo on the rear mount and intercool it
BUT HERES FOOD FOR THAUGHT!

Stage 1 Turbo Kit

Stage 1kits comes with aluminized crossover and down pipe. A 70mm turbo and blow off valve are standard. Kit is designed to bolt right in on a 99-06 GM 2 wheel drive truck. Rated at 7psi max.


• 70 mm turbo
• 38 mm gate (vented to atmosphere)
• 44mm blow-off valve
• Aluminized steel crossover and down pipe
• Swept runner thick wall turbo manifold
• Air filter
• Cold pipe with bead rolled ends.
• Silicone couplers and clamps
• Oil pressure and return lines
• Oil pressure and return fittings
• 02 bungs
• washers, bolts and nuts

 

Totally agree with this or forged pistons on the 5.3 for a few hundred. Had the 02-04 cam, stock 5.3 and 8-9 lbs on a 67mm when I got my best time.

 

I already have a bigger turbo. I have a t4 1.00 hot side with a .70 or 80 cold side .. Tial 44 wastegate, snow meth and injectors. The intercooler I have though is air to air and isn't real big I think 4" thick by 13" wide 25" long. I just don't want to lose realiablty (if that's a word) in my truck sometimes my wife drives it. I'm just goin to have to break the welder out again I guess. Thanks guys for all the responds so far.

 

another vote for ls6 cam 6.0 with BOOOOOST!!!!!

 

sounds like you have a decent rear mount setup
you shouldnt have any issues with reliability you gonna have a stock 6.0 motor with a stock z06 corvette cam
Will idle smooth like stock with no surging
Should drive like a stock truck

 

Or you can trade me my cam for your TR220
