Howdy all! 1.4 tdi questions

[unclesfunnyonions]

Hi everyone, as the title suggests ive got a few questions relating to the 1.4 3 pot.


Right, first off, what are the main differences between the lupo (75bhp)
and a2 (90 bhp) engines? Im thinking along the lines of turbo, inlet manifold
etc. Obviously it'll run a different map, but after serching the web all i
found was that the Audi ran a lower compression ratio (18:1) than the
vw (19.5:1) suggesting it runs a different turbo.


Any info would be greatly appreciated, part no. and the like. Also your
experiences tuning said 3 potter!


Regards Alex.
