Denalix's 2014 Sierra 1500 built 7.0 turbo build
DenaliX14 posted a topic in Vehicle BuildsOkay, after 11 months of agonizing mishaps, set backs and over all triumph, I figured it was time to immortalize my truck in a new post. Please welcome my 2014 GMC Sierra 1500 7.0 (427) Turbo Build! Block: Texas Speed and Performance Darton sleeved boost ready block; 7.0L (427). TSP Forged wet sump crankshaft 4.0" stroke 6.125 Boost specific billet I-Beam Rods CP 4.125 -12cc Dish Pistons w/upgraded wrist pins. Clevite main bearings Clevite rod bearings ARP Main stud kit Cylinder Heads/ Intake Precision Race Components ported Cylinder Heads w/ valve job PAC spring/ Valve Kit. Comp Cams rocker arms/trunion Texas Speed & Performance SV Camshaft +30% fuel lobe TSP AFM delete kit Lingenfelter ported 95mm throttle body Ported L86 intake manifold. All ARP bolts or studs. Fuel: GM ZR1 high volume fuel injectors GM ZR1 fuel pump (high side) Armageddon 465 LPH in tank fuel pump (low side) Snow Performance Stage 3 Meth Kit with controller and braided lines. Turbo: Borg Warner S480 T6 Turbo 1.32 AR billet 110/96mm.

Mishimoto 180 degree thermostat. Transmission/driveline: Circle D pro 3 torque converter 2700 stall. Custom 5" 6061 aluminum driveshaft rated for 1,200hp 7,300trq MORE to come. I need to get the final tune with the new block. Still runs very well on the old 6.2 tune however, going up to 7.0 adds a layer of goofy on vacuum or under boost.. Next steps Get the PATC Stage 4 transmission kit stuffed into my 6L80E and retune to 900+ whp! Hoping to have that underway around March! Let me know what you all think. Ask any question. I'm open to where I purchased parts, cost of build etc. especially my opinion getting into a build like this.
Spark plug recommendation for boosted setup
318z28 posted a topic in 2014 - 2019 Silverado & SierraI've got a 2015 sierra slt 4x4 with a P1X procharger setup on it and I'm currently running NGK 6510 iridium spark plugs. I'm constantly having issues out of the spark plugs when I build boost it starts missing, the boost is blowing the spark off the plugs a little causing it to miss on the top end because it isnt grounding out properly. Just looking for a good copper/nickel plug recommendation around the same heat range that mine are, I'm tired of these plugs and can't seem to find any that will work. Thanks!
If this is posted in the wrong spot, please let me know as I am new. I am looking for some advice from some other guys who have gone down the same path I am about to go down. I have a 2015 Silverado 5.3 and next week I am ordering an on3 76mm ball-bearing turbo kit for it, Snow Performance Stage 2 water meth kit, 4'' exhaust and a converter (not sure the stall, HELP!) My goal is 620-650 rwhp. I have a friend who put down 614 on meth with a 70mm kit and a 3200 stall precision converter. My questions are this because I am not as familiar with this L83. What will factory fuel support? will I need a pump/injectors to get in the low-mid 600s? What would be a good converter to use on the street but also still be able to pull an open trailer with my sidexside (RZR XP Turbo) on it? Who has experience with On3 turbo kits? Vengeance Racing, a very reputable and trustworthy shop here in Georgia will be dyno tuning the truck for me once I am done. Thanks guys!
