I've no interest in the Hyundai D4BH, in addition to it being intercooled, it's also ECU managed; it's pretty simple to add a generic front mounted intercooler to the D4BF.

It's my understanding that there is no difference in quality between the Hyundai D4BF and the Mitsubishi 4D56t, they're the same motor aside for the valve cover, simply manufactred by Hyundai under license from Mitsubishi.

There are several variations of this motor with different configurations of the head/cam, indirect/direct injection, ip/ecu, intercooled/na, etc...

My attraction to the D4BF stems from it's time tested reliability, incredibly simple configuration, and lack of electronics. It wil provide more than enough power and torque for my needs.
