(The intake manifold is often credited with being responsible for the difference in HP between these two variants. The Civic Si being equipped with an aluminium intake manifold, and the RSX Base model equipped with a plastic version).
(The base rsx makes 10 more lbs of torque then the Civic Si due to the fact of the "plastic" intake manifold and it is a dual runner)
this is what type spaz said.....



wow so ur telling me i should swap on into my ep3? lol

 

Your question doesn't make sense? "wow so ur telling me i should swap on into my ep3?" wha does that mean?

I wouldn't put the base RSX IM on anything... lol

Sure more torque by a little but the ep3 IM is the same as the Type-S which is better top end. The SI RBC has awesome runners than them all.

 

ohhh thank you for clearing that up for me

 

lol
