Changing to Bigger Injectors

Recommended Posts

I am removing my throttle body and manifold to be polished up, and while its all removed can i change the injectors to either 550cc or the 650cc saving me to do it when i plan to go single??

 

will i need an emanage to go with this setup and a FSE of some sort? Also i have the ETTC mod so will that make any difference if i switch between the two if the said injectors where fitted?

You will need something to control the fueling and prevent the car from running rich. Minimum you will need is an Apexi S-AFC, but I would recommend the emanage blue or emanage ultimate as a better alternative.

 

You won't need an FSE.

 

It will make as much difference as it does now with the ETTC mod, ie. if you map the fueling for sequential mod, it is going to be wrong when switching to TTC. Personally I would chose to run one or the other and get the car mapped to suit.
