I believe they have a little flatter power band then the older TT ones but not a lot more power, i really just think it looks cool and they are cheap, since i don't have a daily driver at the moment I'm looking at passable daily drivers, and one option is a cressida, and put one of these in it, clean it up really nice, have OK power, so on so on... I'm not an automatic car type of driver tho and getting one in manual is hard/imposable but the parts from the older 1jz and 2jz bolts right on making it manual isn't hard at least not the bolt on parts. so hence me asking, making my 1uz manual took no tricks to the ecu so I'm hoping this motor is the same.
