hey guys I was thinking about dropping a 13b into a miata...but i do not know alot about mazda let alone rotarys..so I was wondering if anyone had done one if it would be a cool swap or if there were any troubles or should I just do a sr20 swap (one of my least favorite engines) but I will if you guys dont think it is worth the hassle of treying to do a 13b swap into the miata..the miata is a 1991 and all help is greatly appretiated
