fyi guys, most honda parts that seem the same but have diff part #'s and cost diff, it usually only means one part was made here and the other over in japan, hence the reason the TSX parts cost more even though its the same as the civic b/c it was made in japan

I believe you are not supposed to use the TSX bearing for this setup, make sure to use the Si bearing or 05 RSX bearing if you are going to use the TSX FD

the k20a type r trans already comes with the 4.764 final drive ratio. as does the 02+ ep3 civic, the tsx, and the 05 rsx-s. the 02-04 rsx-s got the 4.389 final drive. use the needle bearing to match the countershaft you are using. ep countershaft=ep bearing......
