My question: Is it possible to maintain the good low RPM characteristics of the K20A3 while simultaneously improving the high RPM characteristics? A Hondata flash seems like it would help, but a change in cams may be in order. It doesn't look like Toda makes cams for the K20A3, so it looks like we're out of luck.
Why do I ask? Simple. You can get a Civic Si for well under MSRP. My friend picked one up for $17K out the door. Compared tto a RSX-S at $24K, you have about $7K to work with (assuming that you like the look of the Si ;-)). Anyway, if Toda made their engine kit for the K20A3 (or if you could use the K20A kit) and sold it for $2400, you'd still have $4.6K to work with. Is it possible to make a Civic Si perform as well as a similarly modded RSX-S?
