Need help in fitting turbo II fullrear differential assembly and tranny into my 91 miata. Do any of u guys know how to do it or know anyone that did it. Any info would be much appreciated. Thanks in advance.
You must make a front diff mount; the rear ears bolt in with miata bushings. You must make a custom driveshaft. To connect the hubs, you must either heavily modify turbo-II hubs to the correct bolt pattern and bearing sizes, get custom axles made, or have the miata hubs broached to the correct spline. The couple of people who have done this so far have welded, redrilled and machined Turbo-II hubs.
