I have a 93 coupe stock motor and it's a Automatic tranny. I am wanting to go over to a b series with a manual tranny how much headache and extra $$ am I getting into?

 

Why not just sell it and buy a coupe with a manual B series? It's not like the B series is rare to find

 

the auto to manual conversion mount is 250 bucks then all u need is ur b series swap.. not a big deal really.. ive done it like 4 times.

 

You'll need to cut the hole out in your firewall. You'll need to get a clutch master cylinder. You'll need to get a new pedal set for the clutch and the brake. You'll need to get clutch lines. Probably going to cost about $500 to do the conversion.
