I really like the FSI but if I was going to have another petrol A2 I’d be fitting another BCB engine instead.When are you going to try it Steve? I just came back from driving my FSI and think it would be great to bring down the revs a bit for motorway speeds.
I don't think any changes would work out as an improvement. The FSI's engine, and coolant maps are matched to road speed, engine speed, and engine load. Changes from one inlet mode, (stratified to homogenised, etc) to another is based on these factors. If gearbox ratios were changed, the maps would not match any of those factors. Not sure what would happen, but whatever it is, it would not be good. Maybe the European Member has ProBoost, which might help, just a guess. I'm quite happy with mine it is.How about an FSI with a 6 speed gearbox? All the benefits of getting up to speed smoothly, but cruising at lower engine rpm?

Because of the way the FSI's engine and coolant maps work to control the mixture, engine temperature, injection pattern, and inlet air flow, using a range of parameters, including engine speed, load, and road speed. The map knows the relationship between those parameters, and they are integral to it. If you change the gear ratio, you change that relationship. The map would not work, no idea what the result would be, but probably not fun.Don't knock it until you've tried it!

Ah, so now you've changed your tune!A six speed conversion, where the gear ratios of 1 - 5 were close to the original, with a longer 6th sounds like an ideal setup. As you say, maps would probably be fine.

Exactly. I have that car.Member - Petra had an fsi with a 6 speed gearbox fitted by Tony and conversion from Germany and by all accounts it was a joy to drive. If it equates to as Andrew mentions 80mph would be same noise level as 70mph that would be a big bonus. Imagine how quiet it would be cruising at 70mph but noise levels of 60mph, very quiet. I'm not sure a 6 speed gearbox would effect the maps all that much. All you're doing is swapping to lower revs with a 6th gear to within the parameters of the 5th speed gear, the only difference would be a potential greater speed therefore wind rush into the bonnet area - yes / no ?
Very nice, i take it you agree it's a nice improvement over standard?Exactly. I have that car.

Yes. Mechanically the car is good, and the gearbox makes it a nice cruiser. I have plans for the interior and Votex skirts for the exterior. It now has a fully refurbished OSS courtesy of @KleynieVery nice, i take it you agree it's a nice improvement over standard?

Its mucky at the moment, and SORN. I was drawn to the colour as much as anything, and being unique was also a bonus.Sounds very nice, i don't think i've seen a pic of the car.
Current state, on A1 wheels.Sounds very nice, i don't think i've seen a pic of the car.
