A question the likes of which you no doubt get VERY often on here! I have a Zetec Turbo Fiesta which is great fun, and I love it to bits, but I want something with real pace and acceleration, and 4x4, and the Cosworth's been a dream car of mine for many years. (Is there anyone that doesn't apply to?? )

I've been toying with thoughts of Skylines, Supras and Cosworths, as I'd like an absolute minimum of 300bhp/tonne, and I think I'd be right in thinking the Cosworth would be considerably cheaper than the Skyline for doing what I want. Is that right? I don't know what price I could expect to pay to have a standard Cossie YB built up to a 400-500bhp spec, or what work needs doing to the diffs and box to be totally capable of taking that power with launches at the odd 0-60 event and some track action, so could anyone give me a rough rundown of prices if they've done something similar?

Engine rebuild, components, mapping, gearbox and diffs, plus the usual intercooler and radiator prices. Anything more I haven't listed in terms of power? Brakes and suspension etc etc would obviously be seen to!
