RE: Hey Bill and sleeper
Chip and tune - Definitely alternative, Lidio tuned my car and Jeremi's car and we're both satisfied
driveshaft - order an MMC shaft from dennis, it will be drop shipped from dynotech in troy, but for some reason it's 5 or 10 bucks cheaper through dennis
you want gears too, maybe a converter. without gears the stock driveshaft should be fine.
true duals, headers, and good sounding mufflers - order the kooks headers, then have PF&E do the rest of the exhaust. Give them a call and ask how much to install the headers too. It's a big project, the k-member has to come out. I've done it on my car, and i can probably do it in a weekend for the right price (which would probably be less than a shop would charge). Should delete EGR when you do this, and secondary air injection if it's a gen 2. you will need a chip so that it doesn't throw a code when you delete EGR.
brake upgrade - you probably don't need a brake upgrade unless you plan on driving it on a road course. Good quality gen-2 rotors and ceramic pads are usually just fine for daily driving and dragstrip usage. But if it's a stock gen 1 i guess that's an upgrade.
underdrive pullys - still on my list to do. these are a small gain, i'd worry about them after the big stuff is out of the way. Or do them yourself one day when you want to abuse your knuckles. Not really the same bang for the buck as other stuff.
plugs, wires?coil paks - don't bother with fancy wires or coil packs. what year is your car? i'm assuming gen 1 from the wires and coil packs - 97 and 98 cars have coil on plug ignition. as for plugs just go one or two steps colder with a regular motorcraft copper plug. No performance to be had with platinum or any funky stuff NA. Might help with nitrous or a blower, i'm not sure.
maf - skip it unless you're getting a blower. stock MAF flows plenty for an NA motor.
sway bars - i'm not doing sway bars on my car, because of detroit roads. If i do i'll just go one step up on the rear bar so that the rear end is easier to rotate. If you want to do both sway bars i suggest doing the front at the same time as the headers, because the k-member has to come down for both.
I say get the exhaust, headers, converter, gears, and if it's a gen 2, an intake. Of course you'll need a tune. And some upgrades to the tranny, unless it's a '98. Will at least have to swap out the 1-2 and 2-3 accumulators (unless it's a 98).
