If your putting the 20b into a second gen RX you need to use and upgraded flywheel for either a T2 or the stock fd flywheel..but you must use an after market clutch for a T2 try an exedy hyper single they are good...and you can use the stock counter weight from the 20b..

 

where can you get the exedy clutches?
