auto to manual swap isnt cheap. its a lot easyer to buy another 5spd maxima. i've swap auto to manual in a 92 accord and it wasnt worth it. even after the conversion was done, its not 100% like a 5spd. parts cost a lone in the 900 range. laber (me) since he was my buddy i only charged 300.
i know everyone hate HONDAS *civic*, but ask your self why? because everyone drives one for a reason! its cheap a Lego!
