A question to help my understanding

    Hey all,

    I was looking at carzone and the likes and came across older 2.5 litre TDI's and I looked up some info on them and found that one incarnation was a 150hp unit with 229 ft lb of torque.

    The 2.5 is a V6 but one of the 4 cylinder 1.9 TDI's could produce 150 horsepower in its PD setup and had 236 ft·lb of torque.

    I was just wondering if I had the 4 pot PD and then swapped the 2.5 in what difference would I notice? Smoothness in power delivery only?

    The older 2.5 still was a 115 Hp which my current 90 hp VE TDI could get up to with a remap according to Joe at ChippedIre.

    With developments in diesel technology jumping in leaps and bounds Im curious how the older bigger engines compare to the newer smaller ones.

    I thought the 2.5 was a 5 cylinder... in fact I am pretty sure it is.

    My opinion - the 2.5 would probably be a lot stronger and last longer. I have a 150 golf and people say that the hydraulic buckets give trouble in them, *fingers crossed* I have had no bother with mine than feck

    The newer engine would be smoother and more fuel efficient, also cheaper to tax!

    Is that not the petrol one thats the V5?

    So the acceleration would be smoother and a bigger sense of power and strength at the touch of the pedal with the 2.5 150 vs the 1.9 150?

    EDIT:
    Ahh yeah, I googled it and there is a 5 cylinder inline 2.5 TDI in the old A6's as well as the 2.5 v6 found in later ones.
