[Man in small car]

I have a 95 Geo Metro, WHen I was dating my wife she had it, i laughed when I poped the hood the first time. But this is a very good car. It has 90k miles on it now and I drive it every day. It is very nimble, especially in Dallas traffic. It only has the 3 cyl and I was wondering if there was anyone who knew of some mods i can put on this car to make it just a little faster, I.E. 4 cyl motor, Storm motor, anything (besides nitro).. Any ideas would be apreciated :sun: in my Geo
