Hi...

Here is a guide on the Edition 30:-

I don't think the ED30 has any issues but every individual car is different, just not sure there's anything generic.   

The engine with its K04 Turbo on board is more than capable to cope with most things you might want to do with it, for example a stage 1 map without any other modification, expect to see a 15-20 % increase in bhp (expect 275+). If you go for a manual car (and get it mapped) then an uprated clutch would be advisable (DSG  gearboxes can quite happily handle the extra torque once they have been mapped).

An example of what's can be done to and with the K04 Turbo'd car from a well known garage in the south, JKM Perforance:-

Thank you :).

I would assume the standard clutch will be fine for a stage one? Or am I mistaken?

If I'd want to go stage 2 (which is a definite) then i would assume an uprated clutch would be advisable as well as certain other internals to go with it? Fuel pump etc?

^^^^ with a manual gearbox you "may" be ok with a standard clutch with stage 1 but if you plan on going 2 or 2+ then you may as well preempt any problems and fit an uprated clutch. loads of threads on here on which to go for. Now and again there are "Group Buys" on the forum which are great for getting the bits you need at a reduced price.

Also loads of threads on Stage 1, Stage 2 and Stage 2+ and things required and or recommended for each level such as a High Pressure Fuel Pump, Cold Air Intake, Turbo back exhaust system And so on.
