Oppps! You have the Mitz engine. In that case, you might be able to look at some parts for the Mirage/Colt 1.5L.
Better yet! Get the 2.0L Tib motor. This will give you the HP you are looking for.<img src=icon_smile_big.gif border=0 align=middle>
I am doing some searching for you right now, I will get back if I can find any links for ya.
