Outlaw, the series 5 engine (2nd Gen.) might be a more direct drop in...try gettin like a nose cut, cause the rack from steering box conversion will be a nice upgrade to the old arse system...worked for my 1st gen.
the series 6 adn 7 engines, the bell housing is bigger (than the ones from the 2nd gen), so you'd have to alter the car to accomodate it, unless u get a series 6/7 engine and use the gearbox from the series 5....then ur in business
Neighbour had one a really immaculate RE, and had the entire FC rx7 suspension, rear end, steering rack as well as engine, gearbox etc...said they'd go in the car and work perfectly with minor mods...
great find and good luck with getting it man!
