i was looking at my haynes repair manual and it struck me that they often talk about the turbo version of my engine interchangably with my 300D's engine......... this got me thinking. What are the differences....... and if they are few and far between then what would a 300D-300TD conversion entail???? I am really honestly just curious....... I'm happy with my 300D as is BUT at the same time I'm a tinkerer who likes to know exactly how things work (many times however I have no idea).
