the nissan either rb25 or rb26, they are pretty tough and bullet proof engine. as for the rx7, diff case. to own a rx7, u must have another 13b engine as spare in your storeroom. lol. it only can be your 3rd or 4th ride at home. mind my word, not even as 2nd ride. due to msian hot weather, that rotary apex seal wears off pretty quickly here. lol.

slightly better than the rx7 due to two things, genesis 13b rotary, its a more refine motor from mazda but cant hide the fact it is still rotary, another point is its NA, so less stress on the rotary, but it still need more care and attention and wears off faster than ordinary engine do. and this rotary engines really guzzle quite some engine oil. expecting 1L for every 2-5k mileage depends on the engine condition. i still see many rx7 and rx8 visiting this famous rotary workshop in usj1. lol

better than ori rims ... but its 6kg ++ each ..
