Mods to date on the 91:	What Mods did to my car(power wise)
dynomax free flow exhaust	Gave a car a more aggresive sound. Made throttle response better. Also gave car a lot more pickup and top end my guess about 7-10 horsepower.
160 degree thermostat	Car didnt over heat anymore (This alone doesn't stop overheating you need to also get a fan switch). This mod doesnt give you power but it is a good thing to do if you were to put a computer module in it.
Throttle Body Spacer	Gave car much better throttle response. Also saves gas mileage if you dont floor it all the time. My guess is about 4-7 horsepower.
Open Element Air Cleaner	Gave car much better sound when you get on it. Also better throttle response and little bit more torque. My guess is about 2-5 horsepower.
LakeWood Lower control Arms	Gave car much better handling.
Pioneer Tape Deck 40Wx4	Gave speakers a lot better sound. Equalizer gave better highs. Gave no power to my car just a better sound system.
Jet Stage 2 chip	Advanced timing and fuel curve. Gave the most noticable improvement out of all the mods. My guess 10-12hp.
Accel cap, rotor and coil and bosche +4 plugs with moroso wires	This was meant for a basic tuneup but instead i actually felt a big difference my guess was about 5-7hp.
