Un-Stock 2000 Z71

[macifre]

Hi! I´m new to the forum also. I just traded my 96 Sierra 5.7 for a 2000 Z71 w/5.3L. I need your help guys, I want to get more output form the stock engine but don´t know where to begin... It´s kind of a difficult task because I´m in Central America with little or no parts available, so I´ll have to order them, I´ll need all the info I can get, websites, stores.... I was thinking about an exhaust system and Chip upgrade or modifier....

 

Which is the best way to go? mmmm... I´m also on a $1000 budget....

 

Thanks for your replies, will be greatly appreciated..

Also, Westers ECU is supposed to be really good as well, but spendier.

Here is the list in order of what I would do:

 

1. Get a K&N FIPK (not just a drop in filter) and try to find it on Ebay. They are on their all the time brand new for $199 or so which is basically the cheapest anywhere

2. Get a free'r flowin exhaust in any brand (sound) combo you would like. A high flow catalytic converter would be a good step as well. ($2-400 typically)

3. A good reprogram can be had from a number of places. I personally do not have much experience with these. ($2-400)

4. I have seen/heard of significant gains by adding different roller rockers to the valvetrain assembly and getting 15-20 RWHP which isn't bad for the typical $150-300 range depending on the brand and size. I believe that these trucks have 1.8's or so. If you wanted short spurts of power, NOS is always a cheap way to go at virtually under $550 for a good dry kit. Easy install and is what most F-body cars are running and will give you adjustable HP.

 

Good luck and have fun....

Thanks for the info, I´ll start looking into the sites you mentioned. I was thinking about buying the Hypertech programmer.... what dou you think about it?

 

On the exhaust I´ll buy it from a local manufacturer, 4" from the manifold all the way back. And I´ll install the K&N for better breathing....

Most people say that they got very little with the Hypertech 3. I would go with Westers, Nelsons or PCM For Less before HPP3. If you want a handheld try Diablo Sport, SPE Proflash or Superchips before the HPP3.

 

With exhaust you do not want to go 4" or you will lose a lot of low end torque. A big no no in a heavy truck. If you go with true duals then your pipe size should be no bigger than 2 1/4". If you go off the Y-pipe then you can use a 3" in 3" out. or 3" in dual 2 1/2" out.
