Hi are there technical mechanical differnces between these engines -
looking at the way the power and emissions it looks like larger injectors and a remap have been done.
On a web site .... a forum member claimed if you look at all the part numbers they are all identical (this person was located in Russia) ..... can anybody verify this. His claim was all the engines are identical and that software is responsible.
However if you go onto Superchips Bluefin web site TD4 can make around 190 bhp and SD4 around 215bhp .......... leading me to think there are diffences ..... ie injectors.
Hope somebody can shed some light on this.....
