Hi guys I'm doing some work on my already T2 swapped NA I went to pull the injectors to have them flowed and cleaned and realized they are the stock NA injectors so I'm wondering If the NA FPR was left as well, what's the best way to check?

 

The difference between the two is the shape. But they both work the same way. The diaphragm in an NA FPR will still react to boost.

thanks, as always rotary rocket your always such a great help! it looks like its good, turns out i think the injectors are T2 injectors, they look red, but have the correct part number... maybe im color blind
