you will need at very least a petrol stop solenoid, a gas air mixer a vapouriser a safety solenoid/filter all new copper 6mm pipework to lpga cop11 standard a filling valve and either 8mm copper piping or hyraulic lpg hose inc fittings 2 heater hose t pieces inc jubilees etc some heater hose and some lpg hose to go from the vap to the mixer. if you want a slightly better kit then you want to fit a lambda control system to monitor and adjust the fuel trim. unfortunately you are spo far down as i may have some parts that would have worked but need to check on car first.

the mixer will need to be for the engine or sourced through someone who can work ouit the venturi size etc. the rest is largely univertsal but there is a risk of getting to large a vapouriser and just wasting fuel and power

remember for max power with lpg get compression up and run lean without being so lean it backfires and avoid ram air at all costs
