I want a fast truck!

Yont283 · August 24, 2002

Alright, here is my problem. I was going to lift my truck but I found out I am going to be doing alot of highway driving for school this year. Oh well, no lift kit. But I wanted to make my 1999 Z71 ext. cad 5.3L a 13 second truck. I will be doing ALOT of highway driving so I need it to be very reliable. What do I need to do to the truck to get it into the 13 second range. I have 4.10 gears on it and simple mods. I want to put a supercharger on it. Do I need new plugs, headers, ported heads, and other mods to get into the 13 seconds. What do I need to do to the transmission and who could preform these mods on my truck. I live in Knoxville, TN right now and would be willing to drive somewhere to get these mods put on right!

I say, put the supercharger on it first then if you need more HP just change the pulley size and do some fuel upgrades and you will get in the 13's

those "bolt-on superchargers" are jsut that, they bolt right up to a stock motor with no mods and work fine, but theres always a way to get a little more. id definatly say super, and a set of "shortie" exhaust headers, and a capacitive discharge ignition system from msd or accel, and if im thinking right, those 5.3L's have the "coil-per-plug" setup, right? if then read this those mods are about the easiest and wortwhile mod to get unless you want to pull the motor and drop in a new cam or modify the heads. higher flowing fuel injectors may give you maybe 5hp, if your lucky, but will run about 200 bucks for a deacent set. then, unless you have money to burn, then get a performance chip, they'll give you about 20 rwhp, but you need to run 93 octane to feel the difference cause a chip advances timing, so in order to not have preignition ping, you need to run a higer octane rating of gas, and btw, a bolt on super works with 87 octane.

this is just my professional .02, since i am ASE certified.
