firstly, that engine in the first pic is supposedly an F20C with a k20 tranny taken from a website
also our sniper friend has forgotten to mention the immense amount of cutting and welding required to fit this engine longitudinally into most cars.. would probably weaken the frame..plus custom mounts, custom driveshaft? etc.
also, isnt the s2000 RWD? so a rear wheel conversion needed from CRV parts? i've seen youtube videos of F20C civics so i know its possible..but still pretty rare..just dont know the amount of work required there
i think the incredibly low price you're demanding is going to be off-set by these other currently hidden costs.
also, 1,35 for an F20C? we didnt have ourselves a road-trip to turkham or quetta now did we? you do know April fools is 3 days away right? Just making sure.
