demuire Posted September 14, 2004 Report Posted September 14, 2004 As some of you may know, I've been on the lookout for a 4.3:1 ratio for my T-series diff (and an LSD if I can find one cheap enough). Anyway, as far as I know my diff is out of an RA28 Celica (so I'm told anyway), and has a 3.9:1 ratio. Center is broken, missing bits that should be there. I did count the teeth when I first took it out, but have forgotten now, but I think it was a 43/11 ratio (3.909). Anyway, I was speaking to the boys at Option1Garage the other day (they seem to be the only people I can get an LSD or gears from, everybody else seems to talk a lot and not deliver), and they had a Cusco center and ring gear. Ring gear out of a 4.3:1 ratio, 43 teeth. But they don't have the pinion. Now, looking at this page, it says that the TA23's and some other Celicas had a 41/10 ratio (4.1:1). Not sure how well this applies to the Celicas we have here, but I do know that most of them came with a 4.1:1 ratio so could either be 41/10 or 37/9. Also, was speaking to Chin (Acoustic) when I was back in Malaysia, and he mentioned that he's got a 4.1:1 now, and he's looking for *just the ring gear* for a 4.3:1 because then he will have a 4.3:1 (reusing the 10-tooth pinion). Is this true? Can ring gears/pinions be swapped with each other like that? Or do they have to match each other? Quote
demuire Posted September 14, 2004 Author Report Posted September 14, 2004 People on Toymods recon this could be a negatory. Quote
demuire Posted September 14, 2004 Author Report Posted September 14, 2004 OT: Wow talk about price difference... TA22 diff center from Wacol: $75. Whole diff, $100. TA22 diff center from Kelly: $175. Whole diff, $220. Quote
Redwarf Posted September 14, 2004 Report Posted September 14, 2004 As far as I know, you can't mix and match like that, I believe that you require the right pinion for the right ring gear. I know that this is (apperently) the case with Corolla ones.... :P Quote
Nitephyre Posted September 14, 2004 Report Posted September 14, 2004 what's involved in changing diff gearing. ie: for my car, the diff is the same as an oz Crown I believe.. but it'd be nice to have a bit better acceleration eventually. thats done by changing diff ratio right? Quote
demuire Posted September 14, 2004 Author Report Posted September 14, 2004 Changing diff ratio can help acceleration, yes. bigger number = bigger acceleration, less top speed. Quote
Nitephyre Posted September 15, 2004 Report Posted September 15, 2004 mmm ok.. i guess long gearbox ratios (3spd auto) don't help also eh Quote
