3c turbo - it shoves out good solid torque (like a slidehammer), if you are taking up an engine swap and already have done a 1C swap i believe you know how to work on diesels - so setting it up will not be an issue.
the first big difference are the fast glow plugs - and its fast timer too (Fujitsu Ten unit) , - i'll tell you how to wire it up when you get it. block the EGR as it only causes retarded power (but a cooler burn too) - if you bought the a/t version chuck out the throttle valve
