| Isn't the problem with the 1.6 diffs the tiny crown wheel, rather than the diff it's self? The 1.8 diff has a bigger diameter gear and is a lot stronger - MX5OC will have details of how to swap to a 1.8 diff. Get the big diff then get a spangly Kazz upgrade.
I'm running a 1.8 diff as a welder in my 1.6. |
