Will echo what Dave said, I will tackle about anything, but won't do
differentials, nor do I have anybody local I trust to do it. The
differentials were generally pretty quiet when new, but from what I have
read and experienced a rebuilt may or may not whine a little at certain
speeds, pretty hit or miss, the one I replaced was rebuilt and made a lot
of noise. Plus the Nissan unit was designed to take much higher torque and
hp than the Triumph diff, plus limited slip (I autocross too).
I don't think the diff swap changes the character of the car at all (kind
of like pertronix, reversible, doesn't really change the car, just modern
and pretty bulletproof) I hear a little more engine noise and a little less
differential, that is a good thing.
I converted my existing transmission to overdrive rather than going with
the five speed conversion because I like the whole Triumph driving
experience too.
Ultimately, you own your car, do what you want with it.
