@ Dave,Im doing Croft and Nat Day this year.Both events normally have a good turn out of RS Turbos.Can think of 5 off hand who are regular trackday cars.All tuned by Karl at NMS.Plus the grey Jam Sport car in Perf Ford.I used to do Castle Combe RS show every year on track,but its 3 or 4 yrs since I last done it.Best of luck with youre engine,get it sorted,bigger and better as they say.All the best,Micky
