03 turbo ecsb Sierra z71
#1
I have decided it is time to let go of my truck. it is a 2003 gmc z71 extended cab has a herculiner bedliner and a gm tonneau cover it is extended cab with four doors. power windows and locks, steering wheel controls, heat and air work flawlessly interior is in mint condition. the rocker panels need replaced, they are rusted. This truck is highly nodified. i will try to sum it up in this ad. The truck is turbocharged and runs low 12s high elevens in the quarter mile that is approx. 600 wheel horse power in a 5600 lb truck.
ENGINE; 5.3 liter bored to 3.905 inches, eagle h beam rods and diamond dish pistons with total seal rings, custom ground cam by howards, comp valve springs and pushrods, 317heads. pistons and rods are forged. motor has about 17000 miles since build.
TRansmission; 4l65e built in 2014 has red alto clutches, billet input and output shafts, a sonnax input drum that eliminates the 3/4 clutch failures that these transmissions are plagued by. keflar 2/4 band, super servo and the beast sunshell a tci 3200 stall converter with furnace brazed fins, anti balloning plate and a billet face.
Turbo is a 70 mm 1.05 a/r that has been on the truck since about 75000 miles it is a gt45 it came from ebay, the hotside and cold side are custom built using a ebay wastegate and bov. i also use a devils own methanol injection setup to keep the intake air temps under control.
I run a aeromotive 340lph in the tank with a racetronix hotwire kit, with a walbro 255 inline to supply enough fuel volume to the 72 lb/ hr fuel injectors. im sure im leaving plenty of stuff out. but thos is most of the details.
