I introduced myself back on March 21, the day I ordered an LSA supercharger kit from Boost District. After many travails and delays and heated phone calls and e-mails, the kit (well, most of it, anyway) finally arrived in mid-May, while I was out of the country.
This past weekend my son (who owns his own independent general service/repair shop) and I started the build....
Some background...
The truck is a 1999 GMC Sierra 1500SLE 5.3L regular cab, short bed, stepside, formerly a 4x4 Z71 model.
I'm the second owner of the truck and have had it since 2015. I bought it with 69,000 miles on it, and it now has 95,000 miles on it.
It is stock except for replacing the engine, the transmission, the transfer case, the front differential, the rear differential, and the PCM with the complete 6.0 AWD drivetrain from a one-owner, wrecked, 31,000 mile 2001 GMC Sierra C3 (Denali predecessor) in late 2017/early 2018.
I also lowered the truck to a stock 2WD ride height, added a rear anti-sway bar and upgraded shocks. It also has a Black Bear Performance 93-octane performance tune, the C3 17-inch wheels, and a few other minor tweaks, but still appears stock:
So this thread will hopefully document the final phase of the build. I'm not going for maximum horsepower; and I'm doing some things that some may find incomprehensible. I'm keeping the stock exhaust and - if possible - the stock air-box.
My goal for this project is to have a truck that GM might have built in 1999 if they had had the AWD technology that they put in the C3 Sierra in 2001 (later teh Denali) and the LSA supercharger technology that they introduced in the 2009. I want it to have OEM sound levels and NVH, and not to be identifiable at all as a modified truck to the "general public."
I'll try to put together a coherent timeline, but photos were quick and sketchy as we finally dove into the project. I also have some questions for the more technically savvy members here; while my son is a fantastic mechanic [and did all the swap work installing the LQ4 and AWD drive system in the truck) and I have a lifetime of history of building motorcycles, this is our first foray into forced induction, and the interwebz are filled with contradictory information.
