alright so i have a 91 civic hatch with the 4 speed manual transmission and i was wondering if i got an 88 crx si 5 speed transmission and swaped it into my hatch...will it fit? cause i heard somewhere that they both had diff splines

 

should bolt up, but ur probably gonna need si axles.

 

why would you need si axles?

i started with si tranny in my si. it died. put a 4 speed in for temp. and now i have si again. if you use diff axles you need diff hubs to match. input shaft should be fine... shouldnt have a problem. almost seemslike there was a problem with matching up the input shaft - > clutch

 

alright...thanks guys
