Wondering if some one can tell me the difference between these parts on the si vs. the rsx-s and any benefits of the better part.

Fuel rail
Injectors
IM

I know the IM are different whats better about the rsx type s. As for fuel rail and injectors I have no idea. Thanks for the help!

 

whats IM?

hmm i onlyknow that ep3 runs k20a3 and rsx-s runs k20a2 *shrugs*

 

i don't know about the rest but the rsx-s has the same IM as ep3 but the base rsx has a different one, i don't remember what it was about it but it was suppossed to be worse then the ep3 and dc5-s(longer runners or smaller diameter, sumthin like that).
