jmod (I did a shift kit, less than $150), trans cooler (less than $80), 1000 cca battery and a 200 amp alternator (less than $300), 245/50-16's (you are gonna have to replace the tires and battery in a few years anyway, improve them). Higher capacity alternator insures no electrical gremlins that these cars get as the stock system gets older. Swiss-cheese the front of the stock airbox with a hole saw lowers the intake temp and is a slight ram-air effect at 'speed. Provide the labor and do a walbro 255, less than $250. +1 on sawing off the mufflers, I have 'quiet ' cars, my Mark sounds GREAT with the mufflers removed.
