I dislike people misunderstand diesels. The reason it smokes is because it probably runs 13-1 to15-1 compression to fit as much boost into the cylinder as possible without raising egts and peak cylinder pressures to beyond what the bottom end and head studs can handle. When idling, all diesels (especially racing diesels) run very cold and will never heat up to proper operating temps until revved for a while or driven under load. Hey "s13mofucka" this thing would probably toast your 240 if you even have one...
