I drove my bosses Skyline today it is a 2.5 straight 6 single turbo one. It didnt seem that fast, i gave it a boot along a bit of road near me where we take cars to have some fun and i wasnt overly impressed. My valver feels faster. It most likely isnt faster but it does seam faster and i only got similar speeds out of the Skyline compared to my Clio along that bit of road.
