You're right The noise of the X-flow is great. The current engine is a fairly standard 1600 and a little week when it comes to performance driving. The Duratec I've sourced is a 2.3 and I have already acquired some Cosworth internals, Individual roller barrel Throttle bodies, Hot cams, Lighter flywheel....etc....etc. I will be mating it to the T5 I currently have with an RWD Motorsports alloy bell housing. It should be fairly easy to get 200+hp with the build. I figure with the Individual Throttle bodies I should be able to keep some of the X-flow-esc induction noise and with the right exhaust be able to obtain a little of the Exhaust note (Though this might be harder). Either way I'm looking forward to the process and the power gain.
