MX5 Donor

[MoysieWRX]

Have a 1.6 Mazda MX5 Import (eunos roadster) as a donor (92-93 K Reg).
Hoping to start my build soon following saturns guide, once i gather my steel.

Does anyone have electronic copies of workshop manuals/ technical info etc on the mx5/eunos that i could maybe get a copy?

Someone i know thinks that this car would have a LSD. Could anyone clarrify or dismiss that this is a possibilty? Could you tell by looking at the diff if it is a LSD?

Can anyone recomend a good forum/website for Mazda MX5 info and Engine tuning?

Regards
