actually....
since it's more expensive to "slap" a turbo on a VR6 (which means if it's too expensive for you you'll go cheap) you'll probably come out with less power than you would by putting a turbo on a 1.8t which costs less money. if you checked out the ATP website you'll notice their turbo upgrade prices and power you'll make.

anyhow, you're right. it's all opinions. if a person really wants to make power they'll make power. you just gotta do it the right way.
