I got this 1991 Lexus LS400 a year ago and I want to do some preventative maintenance I already replaced the timing belt, rack and pinion, ball joints, seats and some other little stuff here and there. what else can I do to get this to the top performance and I don't mean like lowering it or changing some cosmetic things. I'm more mean like better engine performance that will help out the engines lifespan if that makes sense.

Some little stuff about the car

It has about 157k miles on it and it has cloth seats with the sunroof. And it has a car phone. And it has an upgraded stereo I believe it's Kentwood As I like to put it. It's kind of like a Frankenstein of a car
