Here's how you fix this mamby-pamby wishy washyness. Got get an Audi A4 2.0T and try modifying it out to the same level as a stage 1 LGT and then come and tell me which car was cheaper and easier to get more HP out of.
Stop being a whinner and get a LGT or a 3.6R and quit being a goof. There is no way that you'll be disapointed by the performance of either Legacy. The 2.5i CVT base model is basically gutless compaired to either of the forementioned cars. 265 HP from the LGT and 256 HP from the 3.6R, how can you even say that they are compairable to the 170HP of the 2.5i engine?
