i have a 90da w/ auto trans and blown engine. im buying a 91da w/ manual trans and good b18a it has severe body damage. anyhow on the swap any special things i need to switch over such as harnesses,computer etc. besides the basic engine, trans, shifter, clutch/brake pedals. also is the hole in the body for the shifter or do i have to cut one? any and all info greatly appreciated. this seems like a lot of work for such an older teg but i just couldnet stand to see them both crushed so i figured i make one good one

 

trans , flex plate instead of flywheel linkage instead of cable, half shaft is different chance out the ecu and passanger side engine mount is different

 

hey bro i crashed my 91 integra (auto) and got a 90 integra with a manual tranny in it.... so i took jsut the motor out and swapped it in the 90.. everything is the same... Obd0 and everything mounts up the same... nothgin different expect the clutch set-up, the pedals, cables and flywheel...and u need a new driver side inter shaft for the axle... new motor mounts a plus ! and some patences
