This BMW E30 was built by Ivanov Racing Works in Alicante, Spain for Spanish drifter Santiago Plasencia. The car was powered by a 3.5 L M30 inline-six however Santiago wanted to swap that for a turbocharged 2.0 L 4G63 inline-four from a Mitsubishi Evo 9. Behind the engine sits a manual transmission from a Toyota Supra.
