I got the V6 in a 91. Don't know a lot about cars so you guys think you could get me some specific names of what to buy to increase horsepower and acceleration.

I always wanted to be the first to say this, so.....3.4 out of a 4th gen would be good. I still have yet to do it myself though

It's your friend...

will be your best friend. 3.4l is your best bang for your buck upgrade and then go from there.
