Only dealt with them once when they first got into using the tall blocks for 1.9 conversions, although all seamed well with the car I did a deal on another car with my mate by means of a swap but 2 weeks after he had it he had a nightmare with it, and this was only 6 weeks after the fresh engine install, I went back with my mate to SE and was basically told tough sh*t in a nutshell as I waved any warranty by selling the car
