Engine 2-3k (depending on spec) are you going to remove and rebuild it and refit etc yourself? you could save money there? Management - EMB? TD do a package supplied, fitted and mapped for £550 and it will do 300hp on its limit. TD have proven this many times. For 350-370hp standalone would be your best bet and those are a lot more money WOLF EMS was £1100-1500 supplied fitted and mapped by TD. Turbo kit - if you want 350-370hp, I think most go for gt28? Please guys correct me if I'm wrong! 2-2.5k + Turbo kit - if you want 280-300hp. A billet td04 will do this perfectly but still looking between 1500-2k NEW for complete kit. Manifold, downpipe, screamer! Everything needed to fit! The list really does go on: Intercooler (unless comes with turbo kit) Injectors Fuel pump Fuel pressure regulator Clutch LSD Brakes Exhaust Electronic boost controller Sorry to go on, I personally think you could do it with 8k but you may have to find some bits second hand. Keep your eyes peeled for the bargains. Hope this helps mate!!
