the absolute most horsepower ever produced out of a 1.8T motor is just now breaking into the 600's and its the full on drag car. and he has a TON of money invested. with a chip and full bolt ons you still only make like 220 hp, if you are lucky, big turbo setups only see about 350 - 400 depending on the build, i have also been in some VRT's again that i was just unimpressed by. i have riden in fast civics, fast 240's, and they have only a fraction of what it costs to big turbo a 1.8T. Then the problems . not for me, i'd rather keep my 1 of 7 sets of schmidt race 2k's in america! wich are now 50/50 polished cream
