why do you want to have 100h time PIC for conversion never heard of that, and based on what? then if you are not instrument rated and flying in real instrument condition on training with your instructor you can't have these times as PIC, but if you fly under VFR conditions and training with your instructor then you can log then as PIC times. All your logged times a PIC count doesn't matter you did that under FAA or EASA. So everything logged as PIC under FAA training is PIC for other licenses too. and for your information you are better spending money on time building under FAA license (real IFR are better), because FAA and EASA are working together and FAA license and EASA license will be compatible. FAA issued an A/C about that and weirdly nothing been issued here in Europe......
