If you spend the £100,000 all around you'll end up with about a 600-700bhp Supra. And if you're gonna start modifying cars, then i'll take my R34 on my list, bore it out to 2.8 litres, stick two Garrett GT40R turbochargers in it, 150hp shot of nos, empty the whole interior out and just have a carbon fibre dashboard and a carbon fibre based Sparco Evo II bucket seat in it with Takata 5 point harnesses, replace all the body work with carbon fibre versions, put a HKS 5" Stainless Steel exhaust system on it, two K&N 57i induction kits on it, two GReddy BOVs and a fully re-tuned ECU by Motec. Then replace the brakes with carbon ceramic AP Racing brake calipers and pads and Wilwood discs with Volk TE37s on it and that will put out just over 1200awhp and hit 220mph+ :D. But i'd like not to have done up cars in this.
