Well to change the shifting, if you have a 4 speed automatic you could get
whats called a AutoTransceptor, I Think rksport.com has them, along with a
few other places that will be cheaper, it firms up the shift points and the
car will want to downshift more when you get on it.

As for more HP, best mods are a CAI, a crank underdrive pulley, they show
the best gains for the least amount of money. alot of stuff like special
sparkplugs and wires, ECU's and FMU's are just a money pit.

Check out www.domestictunerz.com for more help, there are tons of people
there who had played with the 2.2OHV and the 2.4DOHC motors and will be able
to tell you what works. My username on there is Parallax, so check it out.

The best resource is http://www.j-body.org

Read, Read, Read

And search before asking, otherwise your liable to get flamed lol

Actually you'll get flamed no matter what you post... they've all seen it
100 times before.

Also try clubcav.com

its mostly for cavaliers, but the motors are the same so they will be able
to give you alot of help.

also go to http://www.highrevmotorsports.com

they have the transceptor there for $150.

Thank you all for your great advice; I will investigate every avenue you
have presented.

I know that improving air intake can improve performance somewhat... what
about the exhaust system for this car... any advice there?

If you're going to replace the airfilter go with something like a K&N. It's
a higher flow filter which will allow for better breathing. Same with the
fuel filter, look into high er performance models from Holley etc.

On the ignition side you can always upgrade your plugs and wires just to
start.

On your tranny question, before you do any mods, just change the fluid and
filter and maybe go to a higher grade tranny fluid like from Royal Purple.
That way you'll have a better baseline to judge where you want to go from
there before spending any more money.

These items won't run you much more than you'd pay to do basic maintenance,
but will probably get you that 10 extra horses you're looking for with
hardly any work or expense. If you want more after doing these basics, then
you will have a better platform to start with.

Good Luck and have fun with it!

BTW; If you're new to usenet, a word of advice, munge your email addy in the
header so the spambots won't pick it up. I notice you're using Outlook
Express, just go into properties and add something like "nospam" after the @
and before the server name. It'll save you hassles down the road with spam
and still let anyone who wants to answer you privately to do so by just
removing the "nospam" part.
