Altezza diff question

[grahamd]

Norbie's right - mine is a 4.3:1 and would love to get my hands on a 3.5 or 3.7:1.
Usually take off in 2nd gear because 1st is too low.

[Norbie]

It's not hard to get a 3.58:1 ratio for an F series, that's what I'm using now.

[{Mr Crabs}]

Thanks all for you your help ,I knew they had a F series diff.I have a MA61 rear end to fit in my car with a poo LSD.+ reps to all.

Norbie - what car is the 3.58 set from?
Wonder if the crown wheel & pinion would fit my IS200 housing.

[Norbie]

RA65 Celica with manual transmission. I believe the RT142 Corona with manual and IRS will also have the tall ratio but they're a lot harder to find.

And most of the celicas and coronas have done 300000 klm now so there getting a bit tired , beware of high klm ones.

quick question.. how would the f-series c&p compare in strength with the a-series? I know they're the same size, but I just can't see an f-series diff standing up to the sort of power your typical modified JZA80 cranks out.

[whatthe?]

I dont think JZA80 and IS200 A series are the same size Greg. Different codes for TRD parts for one thing

PS, I just ordered the TRD F series 1.5 way for my IS200 Gotta love that Aussie dollar at the moment

[Draven]

well then, that's a homo way to code diffs
Was under my car today, and the diff did look undersized... but that could just be compared to the big fuckoff getrag gbox

[Norbie]

JZA80 A series is 200mm according to various sources, which is approx 7.9".

[Draven]

that's a much healthier number.

[whatthe?]

About G series size. Pretty safe there you'd reckon

When Toyota went to the A/B series they seemed to have lost the plot.
The Supra A series is much larger than the Lexus A series. Very strange system.

Have a couple of B series Soarer torsens and they are still larger than the Lexus A series.

Went to Toyota today and they don't sell the 3.58:1 CW&P for the Celica or Corona anymore. Will have to shop around for a 2nd hand unit to try.
