I hear engine parts are expensive BUT i wouldn't let that stop you. In my mind i would drive it till it can't give anymore and update to the 3.8 SOHC MIVEC (roughly the same HP) which is not a rare engine.

33" A/Ts and some sliders to protect your investment and ride. don't worry about the bumpers. Maybe take the covers off for the gnarly trails.
