nice mate.i am also getting a highflow,but i am getting a slide highflow,just waiting for delivery at the moment.be interesting to see the difference,i will post power figures when i get my turbo on and go on the dyno.both the gcg turbo and slide highflow look very simalar,slides highflows are bush bearing and gcgs are ball bearing.at the moment my car has 260hp at the wheels and the best 1/4 mile so far is 13.5 at 165kph,not bad for a stock turbo and the car is auto aswell,i expect the power and 1/4 times to improve when the highflow goes on
