Ignition and service parts can stay completley original. HT leads, ignition leads, dizzy cap. Cooling system can stay OE too, no need for silicone hoses.
Modify the bost circuit, adjust the carburettor, T25 turbo. Intercooling wise it would be nice to keep the engine bay as OE as possible, wondering if you could get away with a grill mount. The other option is a Forge FMIC, would a double capacity 'breadbin' style intercooler be sufficient? You could get the silicone I/C hoses in black to give it the 'oe' look.
