Right there is a few ways you can do this and not everyone will agree on this but i think the best way is to get a turbo ECU and get everything else that runs it and bolt the lot a FE engine. Parts i used when converting the 85, all from a GT, so if its a 91 then just get all Glanza parts. ECU Engine loom Dash loom Inlet manifold, throttle body & sensors MAP sensor Injectors Full turbo ignition system, Coil / ignitor Ignition leads Spark plugs Dizzy Thermostat housing Oil filter housing Sump modded for a return or a turbo sump Intercooler kit VF12 turbo kit, mani, downpipe, turbo, oil & water lines, wastegate & screamer Turbo flywheel 3 puk paddle clutch Think thats it, i used a turbo PAS setup aswell. People may have more to add or say you dont need it all Its really easy Jamie give it a shot bud.
