i think the 89 crx is cable tranny stuff in the chasis...its about 400 i believe for the cable->hydro conversion...not worth it im my opinion.
where r u getting the engine from? hmotorsonline has a LS block for 700, but i dunno if u need everything (ecu, ect) so u might wanna go with the complete change over (check for the price, i forgot), then sell that hydro tranny it comes with and get a cable. unless u wanna get the cable->hyrdo
