G13BB Engine expired, replacement wanted

Hi Guys

My 2001 Jimny had 65k miles on her clock and was ‘tidied’ up to make a big old road trip with a 750kg trailer behind her down to Greece, a fabulous trip and the Jimny went fantastically well, pulling the loaded trailer and a fully loaded vehicle up and through the Mont Blanc tunnel without a hitch. However the trip must have taken its toll and the crank shaft oil seal has gone along with a real loss of power for a week or so before the oil seal went after we got to Greece. It feels like the best option would be to take a replacement engine over with me next time I go over. She is a 2001 convertible with a G13BB original engine with a manual gearbox fitted. Two Q’s;
Would the only engine that would replace the original engine be the same engine model or are their other later engines that would go ‘straight in’ without any conversion work/parts ?
Does anyone have a suitable engine for sale ?
Thanks Hugo
