so im not really into k20 but just out of curiosity what the deff. between the k20s in rsx and the k20 in a civic along with the si civics and type s rsx!!!!!!!! just wondering!

 

I'm quite lost. What is exactly your question?

 

whats the differenced between all the k20s in the cars or is it all the same???

 

I believe this question has been answered numerous amount of times. Do a search around here.

In before the lock, if anything.

 

This information can also be found anywhere outside of Honda-Tech, by the way.

 

K20A3/SI and base RSX................K20A2/RSX-S..............do research son!!!

 

like they all said, its been beat to death on here, but to keep it simple, lots of things vary including compression ratio, cams, cam durration, cam lift, cam lobes, the heads, etc... all adding up to about a 40hp difference between the two, the better of course being in the RSX-S (02-06) or Civic Si (06' and newer)
