This is my favourite. My mates 997 turbo, remap, exhaust, cats, headers, filter, and lightened flywheel. Running 560-570bhp.
The GT2, running 660bhp. The intercoolers on that alone cost somthing like £9000!! Total mod cost is around the £40k mark.
You can see the extra mods have made a good difference. The GT2 was also running £150 less than us.
