Is it worth it?

Ok right now i have a 91 integra and i have thought over the course of the last year to fix it up and make it fast i've thought about the engine swap or just going turbo but the problem is there are a bunch of little things wrong with my car that i'd have to fix like my interior isn't exactly mint i mean its not shit but i'd have to replace my 2 front seats also my a/c doesn't work i have a leak on the passenger side and occasionally water seeps through my drivers side window doesn't work and just little things like that i've also been thinking about selling it and buying something newer like a eclipse GSX or GS-T any input would be appreciated

Might as well sell it and get a newer car. To make that Integra fast youre basically going to have to rebuild every part of the car. Better just to get a car that was already designed for sport driving.
