Hi guys and gals, i have a nissan silvia s14a it is heavily modified. The problem that i am having is that the car starts fine however when giving it some gas it reaches a certain amount of revs and acts like its going to stall or die. when releasing the gas pedal once it starts to die it seems fine but obviously when i put more on the pedal driving the revs up it then acts like it about to die again. in first gear it seems fine but have the same kind of problem when in second and try to give it some beans seems like its gunna stall or die the same (loss of power) any thoughts or ideas ?
"heavily modified" doesnt really tell much to be honest. What actually has been done? The car has been properly tuned for the setup, right? How did the symptoms start? Anyway just guessing here but could be coils
