hi all, is NA fuel injector difference with TT? i think TT's fuel injector would be higher flow right? im sure that #6 injector have the problem, that why my #6 cylinder misfire. now i got a TT injector from wrecker. The wrecker said that they are the same. i would like to make it sure. can i fit the shock TT injector in NA? any problem of that? if cant use it, any idea how much for the NA injector and the parts number? i think i need to get a band new injector. Thank you everyone Jack
IIRC, TT injectors are 370cc and NA are 259cc. I believe you can use TT injectors without any modifications besides corresponding ecu changes, but they are not necessary unless you are looking at some fairly extensive modifications (like nitrous) Coz sells them for 134USD, with part code listed as : NIS300-1660015V
Yes. Individual injector control is not possible with the stock ecu so you can't even make it possible by modifying the ecu. It will run rich, as it will still be using the injector pulsewidth of the 259cc injector, and thus more fuel will get dumped. You could replace all the injectors with 370cc but you'd need heavy modification to see any benefits of this. Injectors are one of the applications where you want the smallest flow rate possible.
