Hey guys I just bought an AT B18B. Well i took off the tranny and discovered a weird *** flywheel clutch combo or whatever it is... It looked liek a dome. I was just wondering:

Do I take it of by just removing those 12mm(?) bolts on the opposite side?

I noticed that on the throttle body, the little circle spot where the cylinder for the throttle cable goes had a small cylinder stuck inside of it with no apparent use. I tried popping it out by hitting it, but it didn't budge. Do I need a 5spd throttle body?

My next question is, what other things will I need to change in order to get this into a 5psd car. I've already got the tranny

 

you will need new flywheel (+new flywheel bolts), + clutch kit and then your new MT. you take that dome thing off, you take the auto trany thin flywheel, this will be replaced with a manual flywheel instead.
