2001 Sierra 1500 w/ 5.3L Upgrades?

MROY16 · Mar 29, 2012

Any suggestions for upgrades on a 2001 Sierra Z71 1500 with a 5.3L?

I'm currently looking at getting:

BBK 85mm Throttle body, High Output Alternator, MSD Coil Packs, 6" Lift (Rough Country most likely), Brush Guard, 8-12 PIAA lights for the brush guard, DiabloSport Tuner, and Bushwacker 4" Fender Flares

I already have this on my truck:

Halo headlights outfitted with HID's, Billet Grille, LED Taillights, Sound System, 18" Vision rims with 32" Hankook All-Terrains, Full length Thorley headers with True dual flowmaster 40 mufflers, and a K&N Cold Air Intake.

Any input or suggestions is greatly appreciated.

i Am also looking at upgrading my 99, Just not sure how much i am wanting to dump into it when i get back from afghahnastan, Keep an update if you dont mind on what you end up going with and how well you like it.

That place has some good stuff, but its mostly for diesel. The gas engine upgrades they have I already have on my truck.

Upgrade to electric fans. I guess the next step after that would be a different cam or supercharger

I'm looking to order an 85mm BBK throttle body, any info on precisely what kind of performance increase to expect? I was told that power would decrease unless it was a high power engine...
