It is expected to be no lot of difference in setting up turbo kit to 1.4 engine- it's the same Gamma KIA engine as 1.6- just with reduced volume.
You can take a look at following topic:
http://ceedclub.ru/forums/index.php/topic,3496.0.html- unfortunately it's in Russian only. Some guys in Ukraine really set turbo kit to Ceed, seems like nobody from our club did it in Russia.
I recommend to contact trusted tuning guys in your home country if you have no appropriate experience.
Except kit, it will be needed to change cooling, lubricating, exhaust systems, driving gears and clutch (because of the torque essential increasing)- if above left with no attention, turbo will finish your car (or yours
) very soon.
Price of good solution could be up to 8k$, atmospheric engines aren't so good object for tuning- it's much better (and cheaper) to sell Ceed and buy Golf or Ibiza with TSI.
