On a standard 2litre YB the GT30 is a MUCH MUCH more driveable and FUN Turbo in my experience on both road and track. Its also made the Sierra a FASTER track car in my opinion.... more power for more of the time! more driveable and controlable. Just Suits a 2.0 YB alot better in my experience.

I love my GT30 and should have switched years ago!
