Bro k24a3 which comes in Uk is the same as k24a2 USA, this was a rare k24a3 which came in Accord type S UK It was mated to a long ratio 6 speed trans, Ast5 I think. Other mods I think are not that much custom hpr headers, hondata heat sheild gasket, RBC manifold, K20a2 Throttle body and Oil pump and I think thats it. And kpro of course is the key to extract this much power.
