Home for the basic kit info. Your engineer will need to quote for the work, but probably around 2k Euro or less? I had it done at same time as annual was due - always helps to combine work. Remember your future costs will be less because everything is new (just coming up to my 500 hour magneto servicing). EASA mod 300 Euro. But once you do it, aircraft thinks it is a 182, so budget for a 182 paint scheme
.
Don't forget that what you take off the aircraft has value. I sold all my old stuff - engine, prop, engine mount etc. And the 5k went towards my costs. So overall cost was less than 0-300 zero timing - or close - but now have confidence of everything new and bulletproof A4M keeps turning.
