i want to turbo my 93 b18 i was wondering if i've got to change my fuel pump and injectors and msd my ignition???

 

no offense but all of your questions could have been easily answered through maybe a combined effort of 20 or so minutes of reading threads! but a better fuel pump and injectors will be needed if you want to exceed the hp the stock units are capable of supplying. MSD ignition is a waste of money unless you're trying to push 500+hp... but a better fuel management system is a must and someone good to tune it(ecu upgrade in other words)
