My brother sent off his TD04 to have the 19T setup done with it. It's nice to see what kind of numbers he will be getting from the thing. He went back and forth on options for a while and finally decided that this was probably the most ideal. His car's a daily/auto-x/rally-x car, so the midrange ooomph is nice to have. He's ran a TD04 tuned, a VF35, and an 18G. I've always thought the car was the most interesting with the TD04 simply because it was so very spunky. I've driven it a number of times for auto-x/rally-x and always didn't like the wait on spool up. I run a NA personally, and on tighter courses, I would pull better times simply because he was below the spool range a lot. With the 19T modification, it'll be quite a little beast. His only difference is that he's running an external waste gate and wants to try and keep the smaller, stock exhaust housing, unclipped, if doable, so spool would be even sooner. Any way you slice it, the 19T's a nutty setup.
