Many thanks both.

Assuming I can get a flat pack MX5 chassis (Talon), what are the merits of the Mazda diff case or the Talon one?

Cheers.

OEM MX5 diff case - cheap, lots about. Awkward shape as it's wide at the top. Used in several kits unmodified. It does have a Mazda-engineered failure mode in the RHS arm so it will snap in accident and prevent the PPF from puncturing the fuel tank/acting like a battering ram in an MX5.

Talon MX5 diff case - more expensive, but will be very nicely engineered (I'm very happy with the quality of the Talon parts I have). Much more compact, will give you more fitting options WRT chassis choice. Customisable; you can put whatever mounts you want on it to suit.

Thanks, I think the Talon case looks a neater option.







Ahh, I have just seen the price, £175!

I'll sell you the 6mm thick base mounting plate and oil seal rings for £30 you can have a go at making one your self, shouldn't take you much more than a complete working week to make a jig,cut all the plates with a grinder and weld it together so it's oil tight.
Don't forget the book is called 'build a car on a budget' not 'build a car for free'
Also has every body met my new publicist and Roadster historian 'PorkChop' doesn't he do a wonderful job, he's worth every penny!
(shame he doesn't get paid for it)

Phil
I am not saying your case isn't worth £175, I am asking whether I would notice a difference when driving the car if I went that route.
It's £175 that I don't 'have' to spend.

How the diff is mounted has nothing to do with how the car drives it's how the diff reacts when you apply a turning force to it. If you suddenly drop the clutch at 3000rpm away from the lights or change from 5th to 3rd it lifts the nose of the diff, get it wrong and the nose of the diff can end up breaking free and your back side will be next to it.

I do it for the sheer love of it Phil

And yes, preventing excessive movement at the diff nose is a key thing to get right.
