S1 Exige (you can tell by the dash visible through the window in the engine bay) and a K20 as has already been said.
I had an Elise and dream't of having the Honda engine transplant, but at around 12k for a turn key solution my pockets weren't deep enough. Now an S1 Exige with a honda k20 in, is simple the car of my dreams, one day I will....
