ex_datsun_man

hey all, im new to this forum but was hoping for a little help. And im an aussie bw so im a llittle slow....

i just bought a s2 rx-7 with only 98000 km on the clock
(thats about 60000 miles for you imperial users).
Damn nice car, no rust, one old lady owner, always gararged.
only problem is its an auto. so im planing on converting it to a manual.

ive done this conversion once before but it was to a datsun so it was nice and simple. i know i may need the following parts...
- manual fly wheel (and spigot bearing?)
- clutch assembly- du'h
- clutch hydraulics, master, slave etc...
- new pedal box
- manual prop shaft.
- different g/box crossmember????
- g/box, also du'h
- interior trim.
- different starter motor???

is there anything else i might need?
any difficulties i might encounter?

ps. will a factory 13b fuel injection system and factory ecu work on a 12a?
thanks
