LSCR351

I am new to this board but not to Honda's. I have searched everywhere I can think of for 86-89 Integra, 88-00 Civic transmission internal gear compatability and can not find any information to the question I am fixing to ask, so maybe someone here can tell me what I want to do will work.

I have a 90 CRX Si, that I will I am thinking of swaping a D16Y8 head and intake on to, and converting to OBD1. At the same time I would like to swap transmission gears to like the ZC first second and third gears with my Si fourth and final drive with a DelSol .750 fifth. I know all this is posible to do without any problem, except finding a cheap ZC transmission to take the gears from.
So after looking up the gear ratios for the USDM 86-89 Integra transmission they seem to be the same as the ZC ratios.
Now the question is will the Integra gears fit in the CRX housing?
