I'll move your topic to the right section for you.....Performance and Brainstorming. This is the mechanical problem section.

In addition. it'll help a ton if you don't type in all capitals. It'* like yelling on a Forum. Putting your year and model in your signature by editing your profile will also help us answer your questions in the future.

The Techinfo and LINKS section at the top of the page are always a good place to start.

HOLA AMIGO! Well you came to the right place for expert help, you'll find plenty of help around here.


8.6 0-60? My non SC '99 could do better than that, sounds like you should start with a bit of a tune up. Then you could gut out your air box or do a cold air intake.

Might just want to jump into a FWI (fender well intake) intense racing sells them as well as a few other goodies for your ssei

Don't jump into anything until it'* running right.

I assume you're running 91 octane minimum? It'* required. No platinum plugs, and no Bosch of any type for plugs or O2. These are bad ideas in a supercharged engine with waste-spark ignition.

Do a full tuneup, and check your fuel pressure for starters. Carefully inspecting your plugs can tell the story as to why the engine isn't running right.

Then we can start talking mods to the engine.

well the car has no problem everything works correctly maybe I forgot to tell you that I mexico city is about 2500 meters above sea level and maybe that'* why the car starts a second and half slower , everything works very well , car had a problems starting the engine but I fixed it and now it has no problems..... I use 91 octane gasoline.... everythings works perfectly computer has no problems...

You should be high 14s or low 15s near sea level, mid-high 15s at your alittude I'd think.

I'd start by replacing your plugs and wires, fuel filter, air filter, etc.

Then buy a scantool, check your overall timing advance and check for KR (knock).

If your in the clear you can move onto an intake ($200US) and a modular pulley system ($100 US)

Check your timing and ignition advance again. Then you can move onto things like Headers, PCM, rockers, etc. Next thing you know you will be in the 13s.

What does your boost gauge show right now at wide open throttle?
