i have a d15b1 (dpfi) with a 4-speed tranny.
i'm gonna do a mini me with a d16y8 head and intake.
just wondering if the y8's 5-speed tranny will work too.

 

It should, but from what I read the CRX/Civic Si 5 speed is geared better for performance.

 

thats if your running a hydraulic clutch setup already but if your running a cable setup than no it will be a waste of time

 

I forgot about that part. Fail on me.

 

stay cable for the win

 

yeah, im pretty sure my 4-speed is cable.
what 5-speed tranny's will work for my car? will any EF si tranny work? i heard certain years have different number of teeth. what's the deal with that?

 

What year car do you have? I think the issue is with using the 88 trans on later years (won't work due to what you said). I believe I read that in Honda Engine Swaps written by Aaron Bonk.

 

i have 1990 honda civic hatchback std.

 

your hubs have less splines than regular ones

 

so what 5 speed tranny would i be able to use with the number of splines i have?

 

The wheel hubs only effect the choice of axles. All the axles (88-91) have the same "male" side going into the tranny.

If you fail to understand this, you can use any 89-91 Civic 5 speed tranny you like.

There's another difference with 88 transmissions but that's another topic in itself.

 

word.

 

to answer your question o/p you can use any non rt4wd cable trans from 89-91
