It'll take some wiring

I'm not sure what, if anything special, needs to be done if you swap in a 5-spd tranny and take out the 4-spd. You will want to get the ZC tranny w/the engine, unless you have an Si one sitting around, and you'd want to get the Si tranny w/the Si engine if you go that route.
You won't need bolts, for they bolt right in. For the ZC you'll have to get 89 Teg axles and you'll also have to run two wires from your dizzy to your exhaust cam sensor.
Cost wise....are you doing it yourself or having a shop do it?! Tack on an extra grand or so if you're having a shop do it.
