Duratec Performance is just that - what modifications can be done to the 2.5 Duratec to increase performance.
3.0 Duratec engine forum
Forced Induction forums (Turbo, supercharger and Nitrous)

The Contour is not a 1/4 mile car. All motor 13s is very difficult and beyond most people's budget/knowledge/expertise.

V8 / RWD / AWD: Yes, it can be done - if you have enough money.

"V8/Mustang sound!"
No cat-back or custom exhaust will give you that sound. It's a V6. There are many nice sounding exhausts available.

The SVT exhaust is a single 2.25” to two 2” pipes.

The SVT resonator is the most restrictive part of the exhaust. A popular modification is to replace the stock SVT resonator with a straight through glasspack or resonator. A popular one is the Magnaflow 10435.

19lb injectors will support 225-240 FWHP (standard on SVTs), which is sufficient for most 2.5s.

Terry Haines confirmed that the UIMs from all model year SVTs are indeed the same. Ford changed the part #s because...who knows.

The 5 extra horsepower is a result of:
- later heads being ported, early not
- later heads have a revised/added intake port hone
- .25 compression ratio increase in later years

Rick Miller from Extrude Hone also confirmed that the UIMs from all model year SVTs are the same.

=Non-SVT Duratec Performance=
- One of the most popular exhaust modifications for non-SVTs is to bolt on the SVT exhaust. The only modification needed would be to add a hanger.
- SVT Lower Intake Manifold (LIM)
- SVT Upper Intake Manifold (UIM)
- SVT Throttle Body (TB)
