Why not sell the prelude that you have now, and buy a 5speed? This way you won't do any serious mods in your car before you actually DO any mods, also, save you a lot of money for other goodies like performance parts. I would say sell what you have, with that money, go find a 5 speed, hopefully if you are lucky, one with Vtec!

Good luck

ps. oh yeah, 5 speed is so much sweeter than any auto, ss or otherwise.
