How strong is the stock HPI diff?

[gavsta72]

Went and bought HPI baja kit the other day, so was wanting to know how strong the the cast alloy diff is, and what about the stock tranny gears?

The gasser will be getting the ESP fully champ ported 29cc for now, and eventually the Taylor 35 when i have the cash.
I've got the TR gearbox, Phatdad bones/cups, TR clutch system, Hostile spur, 19/55 and 20/54 gearing.

Thoughts, suggestions?

I ended up getting the IRP diff cup, Blackbone gears, Phatdad shafts, and Turtle diff case. Now it's big bore ready
