Anyway, as i have an engine that has great fule economy and ok power (114BHP,ok for a 1.5), i was wondering what performance mods i can do to it as most of the mods i would normailly got for (Skunk2 inlet manifold.ect) are all for 1.6 D16Z engines, and i dont have the cash for new Cams and cam gears, any ideas?
