i came upon a 93 civic si tranny and i was wondering what work would need to be done to get it to bolt up to my crx si..

 

not gonna happen for under $800.......

sell the 93, buy a 89-91

 

i dont know about not doing it for under $800.

since you already have the tranny, all you really need is the conversion kit, which you can pick up used from a member off here, now if you were to buy it brand new then that + a clutch/flywheel kit then i can see you getting into the $800's

 

due to the mounting difference of the tranny rear mount, custom welding is involved.

The conversion kit you speak of it for B series, not D series.
