Upgrades to make a 86 Honda prelude faster?

Hi, I have a 1986 Honda prelude, 1.8L dual carbourated, 5 speed, 170, xxx miles. I just did a tune up (Spark plugs, Oil, fuel filter.) this car runs really good, and is somewhat fast for being almost 30 years old. I want to do some simple upgrades on it to make it faster though. I have around $250 bucks and was wondering how far that could get me.

No simple upgrades will make it faster, sorry.

Take your $250 and save it for oil changes.

Come back and ask when you have $5000+ to blow.

Get a fast guy to run behind you pushing it.

Replace your air filter… Toss your spare tire… Rip out the carpet… Go on a diet… Anything to lower the overall weight… Subtracting weight works like adding horse power… Mostly… Or just buy an ls1 car
