hi there just my 2 cents worth I have a fg xr6t sedan 6spd auto and its getting fixed at moment so I am driving a fg xr6 non turbs model and the difference is incredabile in the way they drive I would not but a n/a at all not after driving the turbs n when I say they different I do mean regardless off the power but more mean the gearbox side and how much more u need to rev it to do any thing get the turbo for sure
