I would say save up your money on this one, the so called "basic" mods of intake, cam, exhaust won't really produce a noticable change and will cost quite a bit. Especially the cams on this car. I'm assuming that doing the cams on a boxer 4 would be a little tougher(pain in the ass) than your average car, not only that there's 4 of them... So save up some more money for boost, and as benyl said the tranny lol
