i got a 89 civic HB with a 4spd gear box, and i would like to know if 96+ EX 5spd gear box will bolt up to the 89-91 bell housing. I know the 96+ bell housing is hydro and the 89-91 is cable i just want to know if the gear boxes are interchangeable?....are the bolt patterns the same? is the 96+ input shaft different? etc...

you can bolt a 96+ clutch & flywheel to an 88-91 d series motor, and the 96+ transmission will actually bolt up to the motor as well, but the way the transmission bolts to the frame rail is different. you'd have to fabricate a mount and then convert to a hydaulically actuated clutch system.

i don't know if the guts are interchangeable from one tranny to the other. i doubt it though.

 

my fault... the car is really an 89 civic HB(EF9)...sorry for the mix-up

 

well i suggest not to do it urself..cuz i messed mine up when i tried it myself..(91 HF and 93 EX) u can swap over the complete gearing but u'll also will have to swap over the final gear(just the gear, not the whole differential) input shaft should be completely the same.

 

what went wrong with the set up??...thanx

 

just buy a SI tranny dude...good enough

 

if it were that easy i would just do that

but this ex tranny is free

 

i don't know what went wrong, but when i tried to put the housing back together. it got caught and never closed and never released so i was F@#$%..plus this was my first time doing this kinda thing..

there's couple of things to take into consideration...make sure all bearings are exactly the same size(if not u must use the stock ones)..differential won't be able to swap over due to different inlet size of bearing(just swap over the gear instead)..work in a clean area free of dirt,rocks,sand etc.(even a little spec will cause some sort of damage)..keep the parts clean...replace the throw-out bearing relief spring to an SI(new cost about $5)...and finally test fit everything first before u re-install the bell-housing(meaning test fit it in both halves of bell-housing)

 

and if u want to save a little bit of gas..u can swap over ur HF's 5th gear..it will be a little slow but top speed will be higher
