Thinking about selling my complete new turbo system I just finished for my truck. Reason being I want to go with a nice built LSx motor. Thinking of the new GM LSX454 long block but will see. Anyways the kit is COMPLETE I will include BRAND NEW still in the package 50lb Fast injectors and a BRAND NEW aeromotive 340 fuel pump. This kit started out as a KB Racing stainless kit which I opted for a one of the new Magnum t72 ball bearing water cooled turbo. Turbo has a 96 a/r exhaust side and this thing spools up almost instantly on my little 5.3. A JGS wastegate with a 5lb spring and a 10lb spring. I then finished the kit off by going with a House Of Boost 31x12x4 intercooler and had custom mandrel bent flared end piping made to fit perfect. Also the MAF is built right in to reduce the amount of couplers. Oh and all the couplers have t bolt stainless clamps. The bov is welded directly after the intercooler right behind the grille. This kit will make great power and will last a long time. I'm asking $5000+ shipping. This kit is a direc fit for any GMC v8 nnbs trucks with little modification. Actually only thing that needs to be modified is the front center grille support bracket, it just needs to be unbolted and taken out no cutting or anything. I don't know for sure but I don't see why this system couldn't fit a nnbs silverado. My number is (361)945-6837 call or txt anytime for more info or pics. Here are some pics of the kit...

Dumb question, but you wouldnt want to trade that 72mm for a 70mm with less then 1000 miles on it, would you? My boost comes on so violently, I'd like something a lil bigger so I get a lil lag and not spin so damn much...

Please say yes! lol

Lol Nah man my whole system prob has less then 1000 miles on it as well and honostly the turbo spools up prob the same. This thing hits boost instantly with only a little bit of throttle input. I race in 4wd all the time because of this lol. When I get home I'll take a in cab drive around video to show you all. Hey what were your final dyno numbers by the way? I think besides the size of the turbo yours and my setup are pretty close to the same.

I made 543/502 to the ground. But since then I had a lifter eat itself on the cam. So, Geoff at EPS is doing a spec'd cam for me, and I'm in the process of porting the heads now. It "should" be around 600 when it's back on the rollers after all this I would imagine.
