1987 cavalier question

'87 cav 2.0 4i ac, sedan 91000 miles/146000km

any tips? advise? quirks, or suggestions on this model? I'm about to install a rebuilt starter, the dead one wasn't easy getting out because of the a.c. option on the car.

i found a site where a guy hollowed out the air intake tube and added an open-air filter, I'm assuming it's for more power. worth doing? anyone?

I'm bored and want a small worthwhile project for this vehicle
it's already running well and fluids are all new. slight extra noise, very minor, which I attribute to age

thanks in advance for any feedback!
