Volkswagen Golf VI - Wife's gotta Golf - Skoda
>> There are two 2.0 TSi units
There's 4 now! They introduced 2 more revised versions
CCZA - 200ps / 2.0TSi / k03 turbocharger
CCZB - 208ps / 2.0TSi / k03 turbocharger (
no physical difference to CCZA, just different engine software / map)
Both of those remap to the same power, 250bhp-260bhp / 380nm-420nm -- which is sensational. For ~£500 at any Revo Technik UK dealer + no difference in insurance premium if insured via Skoda or the RAC.
The daddies though, the dogs cahoonas, aren't available in a Skoda

240ps / 2.0TSi / k04 turbocharger, larger injectors -- as in the Seat Leon Cupra
265ps / 2.0TSi / k04 turbo, larger injectors, (and in the Audi S3, larger intercooler) -- Leon Cupra R, Audi S3
They remap to ~310bhp. Capable of harrassing some exotic marques on the race track.
I like the fact these cars are well understood from a tweaking point of view.
£500 on a handling pack from Whiteline.
£500 on a Stage 1 remap (+£500 stage 2, +£1000 stage 3)
etc. etc.
The most attractive TSi must be the 5-cyl version in the Audi TT-RS. The new v6 TSi weighs an awful lot more than the 5-cyl which weighs near enough the same as the 4-cyl. I reckon the v6 would impact handling, for not any more oomph than the 5-cyl.
