We now have a bolt in 6 speed gearbox for the FSI

That seems very high for 6th gear, I would have expected closer to 2300 ish. My 6 speed A2 did just over 2000 in 6th.
But that is because it was a tdi (silly me!) an FSI would be more likely to be around 3000 in 6th I guess.

Yes that doesn't drop it down much, i think i see something around 3,200 on mine give or take guessing 50 rpms.
I'd like to see a 6 speed gearbox bring the revs to around 2,800 @ 70mph as a good compromise.

Seconded, 3200rpm by eye.
Interesting 2,800rpm, as that would induce stratiified mode for economy?

Not if you have a proboost ECU fitted!

Andy has a good point. Lower revs don't necessarily equate to higher mpg. It's a bit more complicated than that. The OEM ratios are not chosen at random. The plethora of ratios in, what appears, at first sight, to be very similar car/engine combinations, show that getting the best ratios for each combo is a major part of design and development. The idea that you can take a box (and set of ratios) intended for one car/engine combo, pop it into a totally different combo, and achieve better economy than the OEM ratios did, seems a little naive/optimistic, to me,

Good evening every one.... its been interesting reading the comments and good advice on the 6sp box. knowing that the FSI engine has evolved in what we know know is the A1/Lupo Polo 1.2,1.4 1.6 and 2.0 would it not be better to fit the engine and box from one of these. it might mean some mods but am sure it can work. Any more advance DIY...er ?

TLDR version: If it would fit physically and electronically, it would already have been done. It doesn't, so it hasn't.
longer explanation: The A2 generation is one of the last where the mating of engine to the rest of the car is still relatively small, which is why the 1.8T from the Ibiza / Polo GTI is used. An AVY is a drop-in. A 1.0 TSI is a completely different generation of electronics and it's a completely different ballgame. From my understanding, too, the space under the bonnet is actually also too small - the small turbo units build too high and so they don't physically fit. There's no 1.4 TSIs, but quite a few 1.8T conversions and at least one 1.9TDI.

..and as a reminder, the 1.8T generally means sacrificing climate and *just* fits. It's also a €10k undertaking with paperwork.

The electronics on an AVY are also very different certainly isn’t a drop in, however it does bolt up nicely, but different gearbox flanges etc. The ecu is completely different and requires a lot of wiring work.
