http://mywikimotors.com/n42b20/ NU, pentru ca : "N42 engines are not the best choice for tuning. You may face difficulties in finding necessary dimensions and performance parts on the market. That is why you will hardly be able to implement serious upgrading project. The only way to increase the level of HP is to proceed with chip tuning. You need to buy cold air intake and cat back performance exhaust system. Don’t forget to complete engine management tuning to make everything work properly. Such modifications will make it possible to increase power rate up to 160 HP.If you still require more power the best way is to sell your BMW 318i and buy BMW M3 E46." dupa ce in prealabil motorul "toaca vreo 1500-2000 de ron" ca sa fei readus pe linia de plutire (distributie, garnituri, etc) sa risti un chip pe el...mai bine nu!
