Hello mate,
Induction wise, I've gone for a Cosworth Group A cone filter and trumpet to fit a T3 turbo and fitted it on to the hose that went from the Turbo to the metering unit.
Fuel system goes:
Fuel filter > fuel rail > fuel pressure regulator > fuel return pipe
Brake servo pipe I've used an XR3i EFi pipe. But you can use any silicone hose suitable to draw a vacuum and use the original fittings and fire trap.
