Its makes no sense at all really does it. i ask a simple question to which you answered. Ok there is a hint of sarcasm in my posts but that is just down to my 'warped' sense of humour. So no need for the kind of replies you are posting. Anyone would think this is a car forum for sharing information.

As for who builds my engine, if you do a search on here you'll find that i have never got involved with the whole, MAD vs SCS vs AG vs NORRIS vs HADLAND tuner wars shit......as its completely anal!!!! And alot of people who i know on this forum personally ( who are top people in person ) are made to look like complete dicks the way they have their head up their tuners arse! So please do not put me in the same category. But on that point, yes i do think Mark builds fantastic engines. Thats why i have used him for the past 6 years. Can no one else build a good engine?? of course they can but according to some posts on here you wouldn't think so. lol

ps. i will give myself one of these, as it would seem you do actually use (old) f1 spec springs in your builds
