Sorry guy's I'm at my folks house, and don't have my (dealer) broacher handout that I want to reference. Anyway my question is this. I know that the base model RSX and Current model Civic's share chassis architecture, I know our cars (Ep) share similarly configured k20 series mills.
Reading on in the broacher, I observed that our 1st & 2nd gear ratios are different; the RSX has taller 1st & 2nd gears? Our car is 150-200 lbs heftier, according to the broacher. Our torque curve comes later and is de-tuned to produce only 132 lbs/ft of torque while the RSX has 140 or 142?? Reading further revealed that the base rsx has some sort of advanced technology that enables the intake runners to work in unison with ivtec, by choosing from two sets of intake paths, to improve power delivery also evenly distributing torque. I did not notice our broacher mentioning anything about the variable intake runners? we do share the same k20 right?
Also if in fact our engines are identical, where does Acura extract the extra 10-11 ft/lbs of torque? I notice the RSX has a single exit rear muffler, in theory would cause a bit more backpressure, returning very minimal amounts of torque gain?? I don't know, but I sure would like to know. Also a huge photo in the RSX's broacher reveals the valve cover assy and the oil fill cap, the RS's oil fill cap in the photo shows a recommendation of 5-30w oil while ours shows 5-20w. If our engines are the same what
