What is the exact difference between the engines in the Acura Rsx and Arcura Rsx type S?

They both have 2.0 liter, four-cylinder engine. I know the Type S has more Horsepower. All I hear is that it is "tweaked"


Can one make the Acura Rsx's engine the same as the type S.(By adding to it) what do you have to do?|||The type S has vtec on both the intake and exhaust side of the valves while the base k20 only has vtec on the intake side. type S also has higher compression pistons than the base. So if u were to try and make the base k20 the same as a type s you'd have to switch internals and switch the base head out for a type s heard.|||I don't know the complete differences, but the main ones are





* - better cams with higher lift and duration


* - raised compression ratio from ~9:1 to 11:1


* - intake manifold (IM) is metal and higher flowing, base is plastic





I don't know of the other differences and I don't know if you can simply swap the cams, IM, and raise the compression (probably use Type-S pistons) and have the motor get the same power. There are a lot of other things that make an S, not just the motor. If you want the performance of a Type-S then you should buy one. If that's not an option then do a motor swap for the k20a (Integra Type-R with 220hp) k20a2 (02-04 RSX Type-S with 200hp) or the k20z1 (05/06 RSX Type-S with 210hp) %26lt;-- the k20z1 has 10 more hp over the k20a2 because the ITR cams were used and a higher flowing exhaust was fitted.





The transmission will have a lot to do with acceleration too. Since the Type-S has a close gear ratio 6 speed quicker acceleration is achived. The ITR has an LSD (limited slip differential) which helps use both drive wheels instead of one. This provides better traction off the line and while cornering.|||The base RSX uses a 2 stage iVTEC which basically switches from a very anemic cam lobe set at low RPM to an average set at medium and high RPM, to increase fuel economy. The Type-S uses a 3 stage VTEC which is more performance oriented. Also, the Type S is about 11:1 compression, the base is about 9.8:1.
