There will be very few 4 cylinder engines with the same level of durability as the 4G63. The up spec Genesis 2.0T has an output of 204kW so there has to be some more room for improvement over that (base trim 2.0T is 160kW - figures are from wiki) and guys are always cutting out trans tunnels for SBC/trans combos so if you're not afraid of some cut and paste and could get your hands on a Genesis wreck for cheaps it would be something different.
