TU2J2 1.3 8v Rallye Bigger Injectors
 

Hey guys, I bought 1.3 8v Rallye engine, I want to make bigger power from him. Which bigger Injectors can I use on that engine? Which one fit?

that will not make any difference without also getting more air in and using an ecu that can be mapped

You only need bigger injectors when your current ones won't supply enough fuel for your engine spec.
The Rallye ECU is especially flexible when it comes to mapping, BTW, no ECU change needed. :-)

The problem is that I don't have rallye injectors, and I don't know which bigger ones will fit. That's why I need them

Then just get some standard Rallye injectors and you will be fine with those.
