There are so many obstacles to overcome in doing the 'kit' that it makes more sense to put yourself through doing the turbo conversion Ash style.. And after all that trouble you will be severely limited in the maximum power output because of things like the injectors, high compression and the lack of intercooling. My advice, for $3.7K find yourself a wrecked TT and do a swap. You'll save a ton of money, it will work, and best of all - it will last..
