this is an old D series write up I did but a B series install is essentially the same as well.

this is the basic rundown in order on how to take it out.

-pull starter
-pull axles
-remove linkage (find a push pin...8mm)
-drain tranny fluid while you are down there
-unhook VSS sensor
-remove header
-remove the slave that moves the shift fork and bend it out of the way, i usually sit it on the pass. side fender behind the headlight.
-remove the 4 bolts facing the pass. side mount that hold it to the block (i think 4 might be 5..)
-remove the three bolts that hold the tranny to the rear mount (dont remove the rear mount)
-put a jack under teh tranny to support it and remove the bolt in the pass. side motor mount.
-wiggle the tranny till it comes free of the dowel pins and remove it from the bottom of the car
-remove PP (10mm 12 points hold it on, pretty sure 10mm)
-clutch disc will about fall out
-remove 6 17mm 12 point flywheel bolts

then it's just reverse of install. make sure you put the dowel pins back in the block if they fall out. there are two. the hardest part is getting the tranny back on the block. get one dowel pin in the block/tranny and then move it to get the other one in and tighten down a couple bolts and make sure everything sits right. grease up the TO bearing and input shaft liberally. make sure the shift fork moves easily back in forth on the ball it sits on w/out popping off before you put the tranny on. remember to add oil, either honda MTF or 10w-30 oil. DO NOT NOT NOT USE SYNTHETIC!!!

you only remove the clutch/flywheel if you are replacing the clutch. make sure before you remove the pressure plate that you have the new PP, clutch disc, TO bearing, pilot bearing...and most importantly, the ALIGNMENT TOOL lol....because they are fucking hard to find. its a very good idea to resurface a flywheel before you put a new clutch on it.
