here is a list of some parts I've replaced JUST yesterday and today:
spark plugs
plug wires
distributor cap & rotor
fuel filter
air filter
thermostat (PITA)
coolant flush
few 5/8'' (or equivelent metric w/e) coolant hoses here and there (about 30'' worth)...(PITA)
exhaust manifold gasket (PITA)
trans oil pan gasket (PITA) + new trans fluid + filter
new steering-rack-boots + new powersteering fluid (PITA)
full tank o' premium (PITA, $44 fill up) + fuel injector cleaner.

all these improvements have made a HUGE difference, on top of the other maintence I've been doing to make it better. now this thing will FLY. all I will say is I need something wider than 185s on the back. I'm starting to understand the likeness of the 240z in my car lol...... and I haven't even started on the suspension or interior yet... oh god.....

mos def!
