G'day! um, my friends gota R33 skyline. a couple mods like pod filter, a very mild exhaust and a few computer tricks. He has a switch to change the boost pressure from a bit over stock to much higer.... Personally, I've never driven the car, or know its true quater times, but I just get the feeling its got more go that my T. "Seat of the pants" feel I guess. Its only a feeling, but id say it would be about 1/2 second or more faster down the quarter. Could be wrong; different gearing, different feeling being the driver, - who knows. My T is stock and has only done 1500km.... Having said that, the T has it all over it in style, comfort, stock stereo kicks it. Suspension is so much better too from stock. And I just COULD NOT live with an R33 day to day. Ugly, early 90's jap interiour is just plain crap.... oh and those faded UV damaged headlights that look like toe-nail rot. ...
