Here's food for thought: The R56 Cooper S has an all aluminum engine with a Borg Warner K03 [bigger than the Mitsubishi 10g's on the N54] running 16psig with a 10.5:1 static compression ratio. Straight off the showroom floor it puts 202wLb-Ft to Dynajet rollers SAE corrected. This is on a 1.6L engine that BMW designed. I see NO reason why upping the displacement to 3.0L, lowering the static CR a whiff, running two smaller turbos at almost half the boost would merit any sort of overheating issues. The MINI's engine runs a pathetically microscopic oil cooler that is behind the engine and out of any sort of airflow; the fact that the 135i has an oil cooler in the front bumper is surely going to freeze the oil in comparison!
