Below are the most commonly suggested "first" performance mods done to the 2.5 Duratec, and to reduce the number of "I just got my SVT, what should I do first" posts.
=Remove hoodliner=
This will reduce overall engine bay temps.
=Optimize TB=
Virtually free for a dyno proven 1-2 hp gain.
=Intake=
K&N RU-3530 is the most recommended w/ a MAF adaptor.
=Heatshield=
Create a heatshield to isolate your open intake from engine bay heat (heatsoak).
=Maintenance=
- Cleaning filthy TB, UIM and LIM will do wonders.
- Replacing old spark plugs & wires, properly gapped plugs
See Duratec HOWTO Forum
=Remove stock resonator=
For 1-3hp gain and better sound, remove the stock resonator and replace with a straight through design. Magnaflow 4" round is most recommended.
=Y-pipe=
- Aftermarket, aluminum or stainless
- Optimize the stock y-pipe for better flow. CEGers think this is a DIY mod - it's not (in most cases). You will have to take the y-pipe to someone who can perform the optimization.
=Exhaust=
Cat-back brands available are limited. Most affordable and recommended currently is the Tru-Bendz.
=Short throw shifter=
B&M or Steeda
=Gutting pre-cats=
CEGers have gut the pre-cats ("headers"), especially when they have become clogged.
=Headers=
MSDS or Weapon-R
=Chip=
Recommended as the last mod as to avoid reburn. Nautilus Performance is highly recommended, with Brenspeed being another good option.
=Tunes=
an alternative to a "chip", in which the performance changes are loaded on to the STOCK PCM computer itself. benefits are an easier time changing the tune if you change your modifications. The most COMMON tuning solution is to purchase an XCAL2 and get a tune emailed to you, to load on your own. Contact Nautilus Performance for both an XCAL2 and/or a tune.
=For non-SVTs=
SVT TB, SVT UIM, SVT LIM, SVT exhaust
=Other mods=
Suspension, brakes, forced induction, 3 liter, etc. can be found in the respective forums.
This is a a work in progress - suggestions are welcome to improve this compilation.
