so it works out to about £108 to your door for a pump that is not proven
and for about £120/£130 you can put a pump on that is trusted time and time again
i did look at these pumps as iv just put a new pump on my 3dr but al the end of the day i wont to no the pump is right and wont fuck my motor up fort the say so of £20 to rebuild a cosworth motor is more than £20
