Yes , I had the bigger V8 Airbox with K & N Filters with bigger inlet tubes. Bigger throttle body, larger injectors from TUV and a tune. Sorry I haven't Dynoed the Turbo, not there yet. Had to get a new oil pump, bit of fabricating because it is a different fit. The first pump was so noisy you couldn't drive the car. Nobody is more frustrated with the set backs than me, quite anxious to see it up and running to the point of Dynoing it..
