looking to get bigger secondary injectors, but which ones
 

im looking to get bigger injectors, either 750cc or 1000cc, not sure yet. going bigger turbo in the future. but arent s4 and s5 injectors have a different connector? i cant find any for my s4. it doesnt say which one its for, can someone link me to 750 cc or 1000cc s4 t2 fuel injectors that will fit in the stock fuel rail
