I ran a CA18de and stock CA18det for 5 years on a H165 without blowing up the diff.
For drifting.. better to get a h190 or bw78. I love the idea of cheap parts (unlimited supply) when using the BW78.

Use what's cheap first.. if it's not a daily driver this is a good idea. If you can't afford time off to fix busted diffs, then put something stronger in before you start thrashing it.

i have the motor in a 1200 coupe and i have a couple of spare 120y diffs


i have a skyline diff ready to be shortened and i need to know if im better of just going for the 190 ,but i like the idea of disks from standard on the r31 diff

do the h190s bolt straight in ? or will i need to relocate the mounts?

Hi, check out Tech Wiki related to H190 spec, alot of info you might find usefull.
