SPYDERLK said:The higher C/R should compression ignite more readily. The turbo only helps when its spinning. Both those ratios seem a bit low tho. 16.5 probably wouldnt be enuf to ignite. Im guessing 19/18 resp

Larry, your post made me curious. I just checked my service manual and the TN55,65 is 17.5 where as the TN75 (turbo) is 16.5.
Andn my comment about the lower compresion ratio being easier to start had to do with it being easier to spin with the starter, not the C/R firing off the diesel fuel once it is spinning.
