RA23 diff?

[1UZRA23]

This may be a stupid Question, but how bullet-proof is the RA23 1976 standard differential. How much HP will they take?

that depends on how its treated
on my blue shitter its the original diff ,and its a locked one at that
i have raced on it in four 6 hr races and numerous sprint/track days over the last 6 years
i think the reason that it has lasted so far is i dont dump the clutch , i let the clutch out then floor it
but having said that , i have acquired a volvo disc brake diff assembly to fit in the white 28 when the 1uzfe goes in that
i think the rest of the car will break before that diff

Thank you, the volvo setup sounds like a great idea. I am planning to have my 1uzfe in before Christmas this year, but i am keeping the auto tranny.(wife).

simple answer
change wife , then you can , change gears
(joking lol )

does the volvo diff+discs conversion need to be shortened?

[ian]

that depends on the wheel choice , maybe you can get away with it by folding the lip and pumping the guard a little with a guard roller
they are a little wider someone may know exactly
