Any of you guys on the asian bmw forums?
There's a bunch of dudes running single turbo n54s. I'm not sure if it's the fftec kits or replicas of them but theres a couple different variations. The 1/4 mile is something unknown to most of them though and they normally do high speed pulls. It's mostly younger people with rich parents so their cars are always full out modded. A 335i costs like triple the price over there so that explains why most of the owners have open budgets.
