i have just done this, and done it the hard way meaning i bought all the bits seperate to save money and i enjoy the challenge, but it is still feckin expensive i have a tubular manifold and a T61, i already had a FMIC, AFC, ITC, FSE, 550's, brakes etc so it was the logical step to go single, if it is your long term aim to go single build up the parts over a year or so, i started with a pace intercooler and made the end tanks myself (cost £350 in total) and went from there, i hate to say it and this may upset some of the traders on here but if you go this route get all your stuff from the USA, i would say i have spent £2000 doing this and thats not counting all the supporting mods
