It's a 2.4 liter, natrually aspired, SOHC engine. The extra displacement comes from a 1mm larger bore, and a taller block (I beleive it's 13mm, but can't say for sure off the top of my head) then the 4g63. Other then that, I don't know what else to tell you. Other then it's obviously in the spyders only.
Speed kills, drive Hondas live forever!
