if so i will order

$249.00 for 5-8 whp? there are many many more mods that you can see higher gains for that price. or that you can save that money for to put towards a other mod. i personally believe in udp's but only after intake, headers, exaust, and tune(toms) was done. but do what you will. as far as bolt on and go? sure, as long as you dont have any aftermarket lighting or stereo equiptment. most people that run a udp upgrade their altinators. best of luck to you.

I order that & add a header, intake & a tune.

Make sure you do your research on how to install those onto the Duratec before purchasing. Most say they are more work than they are worth.

Too bad the Duratec doesn't have any woodruff keys cut into the crank snout.

The timing sprocket can move around on you while doing the underdrive pulley swap. In that aspect, it is more similar to doing a timing belt job than just swapping accessory pulleys.

An obx header will give you more for a similar price. Better fuel economy and more response. However youd need a tune.
