STS D21T MK II buggy motor

STS, the Taiwanese RC manufacturer, has released this new team version of their 3.5cc buggy motor. Called the D21T MKII, T standing for team, this new engine features a 14mm crankshaft, a 5 port liner, comes with 2 combustion chambers for using both the turbo or standard type glow plug and the motor itself has been custom made, which suggests some extra hand work done, but we dont know what exactly has been done.
