What can you do with an automatic 2.5L to improve performance?
I have an automatic 2.5L TS wagon. It's very heavy (3100 lb base weight). This weight will go down a little as I swap in 16" alloys. What type of mods can I do that will improve:
(1) acceleration off a start; and (2) higher end power (specifically climbing hills) without affecting fuel economy, being all that much noticably louder, or voiding warranty on a large area of the car (i.e. powertrain)? Thanks for your advice. Let's not go into manuals being superior, and what not--I know they are.

Thanks a lot. But that would void the powertrain. Seriously. What mufflers are good for adding high RPM power? Will an airfilter help? Do I need a performance muffler and intake, or can I just have the one?

You could look at a new torque convertor, or do what someone I know is doing--> get a shift kit, it makes the car shift faster *duh *. I believe Cobb tuning sells em. If you want to look at getting a stick tranny, you should just buy a new car (it would be cheaper than doing a tranny swap).

Any of the engine mods you see listed in this forum will improve power, regardless of the transmission. However, I personally feel that the bang for buck on anything more than a high-flow filter, and possibly a CAI, just isn't worth it. Short of a turbo, you're talking about $1-2k, not counting labor, to realize a 10-20 HP gain.
For long hill climbs, I generally just drop down into 3rd to prevent an up-shift into 4th. |

- Cold Air Intake...GanzFlow, Cobb Tuning etc..
- Lightened Underdrive Pulley - Any exhaust system in the "Products" - Better plugs and wires (ditch the Champions) - Headers - High Flow Cats - Larger throttle body (Cobb tuning) - Air/Fuel monitor and adjustment (you will most certainly be running rich. - ECU reset after each mod. When making a all-motor car, every little bit helps! -Andy EDIT: Oh Yeah, get as much STi stuff as you can and have a dealer install it. I think that is the only way to truely avoid warrenty B.S. |

Use high quality ATF oil to keep the torque convertor cool. too much heat will kill power as well..
