Im thinking about doing a b18c1 swap in my 89 civic wagon, I have the crv 5speed 4wd tranny and I was wondering if anyone knows the ratios if the crvs rears diff and the civic rear diff? Im going to mate my b18c1 with the crv 5speed 4wd tranny and drop it n my 89 civic wagon. let me know peeps

i havent heard any1 done this swap and i want to be the first 1.

if not b18c1 then maybe poor man type-R (b16a2 head and gsr block with b16a2 piston)

 

Somebody on the Wagon website has done this swap and if I remember they had problems with the gear ratios. I don't know what they did to fix it or even if they could. Check it out, it may save you alot of work.

I think the consensus is that you would swap in the entire CR-V driveline (diff included), and make a custom driveshaft.
