Mkii Supra Gear Ratios
« on: Aug 23, 2004, 07:23:05 pm »
Supra gear ratios (mkII)
1982 3.72 standard gearing in both automatic and 5 speed
1983 4.10 available for the 5 speed, auto still 3.72
1984 4.10 available for the automatic, 4.30 for the 5 speed
1985/1986 same as 1984

CODES to look for:
F303 = 3.72 limited slip
F302 = 3.72 non limited slip
F293 = 4.10 limited slip
F292 = 4.10 non limited slip
F283 = 4.30 limited slip
F282 = 4.30 non limited slip

USDM Supras all P-types have LSD, all L-types have non-LSD
In Canada, the Supra GTS (P-type) and GT (L-type) do not seem to follow this rule, keep an eye out for the codes

could this perhaps be made a sticky or something as this is one of the more repeated questions I see?

Don't forget the F312 which is a 3:90 out of the 85 Celica and the 85-88 Cressida's.

Well I did that write up on mkII Supras only if you didn't notice
 :P

If someone else wants to do the research on the Celicas and mkI Sup, you're welcome to it, you can PM me and I will edit this thread or you can make it known elsewhere. The differential codes/ratios are widely needed info apparently

I know this isn't a supra rearend question, but the search feature is screwin up badly. But what is my gear ratio with an 83' Celica Automatic, is it a 3.72 since that what the supras had in 83' on the auto?

Check your VIN plate on the firewall.  Across the bottom are codes for Color/Trim - Axle/Trans.  The axle for your Celica is most likely a "T372" which means it's a non-LSD 3.583:1 ratio.

Damn that would be really low if thats teh case.  I bet I would get a hefty jump in acceleration just by getting a 3.72 or maybe a 4.10 but my revs would be ridiculous at 70 to 90 mph, right?

Yep, pretty much... Mage's car tops out at about 110 with his 4.10s, that's redlining.. My car has 3.42's (stock 82-85 GT and all GT-S's until 85..) and can easily top 100 in 4th..

Hey I was wondering if the ring and pinion are interchangable between the gts celica models and supras. I am looking into getting a LSD from a supra for my celica but I like the gearing that I have now. Thanks

The non-85 GT-S(ST and GT too) Celica all had the 6.7" diff, while the 85 GT-S 5spd Celica and all MKII Supra received the stronger 7.5" diff.

The MKI Supra had a 8.1" diff, you swap in the whole alxe over to a ST or GT MKIII Celica and bolt it on.

I have wondered about the truck alxes, but I have not the specs.

I'm pretty sure the first gen supras use 7.5" F code axles  :unsure:

So if I found a supra LSD I could just bolt it right into my celica?

It depends.. not *ALL* 85 GT-S's got the bigger diff... Check the plate on your firewall for the diff code.. If it starts with F, it's the big one. If it starts with T, it's the small one. Another indicator is your RPM at 60mph in 5th.. If it's around 2100 RPM, it's a T code, if it's around 2700, it's the bigger one.
