The MQ SD33 are 24Volt and n/a, the MK SD33 are 12volt either n/a or turbo
SD33 are a great motor and well like most old commercial or industrial built things are as tuff as an ox
They fitted these engines in forklifts and UD diesel trucks
But, like most things with some age on them , they can be great and last forever or they could fall apart in a headbeat
Theres blokes pumping well over 15 PSI safely in a SD33 with many Ks on it , some are even as game as pumping near 20 PSI in them
They are getting harder to find parts for,usually resulting in purchasing a complete car instead(ya shed full of parts)
Theres a bloke on another patrol forum who has dyno printout of his SD33T, daily driver putting out 400NM at the wheels, not shabby in any language
Youll pay more for a TD42 n/a , than the best SD33T you can find
Both great
