Changing differential gear ration, need help! - Toyota Nation Forum : Toyota Car and Truck Forums

Gen3cruiser · 03-23-2005, 11:43 AM

Hello,

I am hopefully about to get V6 gen 3.5 and was wondering would it a.) be possible to purchase the differential gear from a camry SE and install it into a regular V6, and b.) how hard would it be?

Thanks!

probably not worth it... an auto is slow compared to stick... changing the ratio isnt going to get you back that 1.5 seconds you loose over 0-60...

*manual conversion hint hint nudge nudge ram poke...*

Anythings worth it..if thats what you want to do....
However, I'd have to agree...if you are going to keep the car for a bit ... swap it to manual. They are fun as!!! I've almost got the parts for mine and i can't wait.

In answer to your question..i don't see why the diff gear wouldnt work..it's from the same transmission (i don't think thye change the transmissions for diff models...).

Your just going to waste your money. On a side mount engine the final drive ratio matters little. If anything have your Transmission rebuilt with shorter gears. That is where your really going to gain. Your not going to get much from a low hp vehicle with a modified final drive.

Hey,

Thanks for suggestions on manuals, but not interested.

Smokingtires, you do know the SE is .8s faster to 60 then the other V6 models don't you? That is a good difference if you ask me, 7.5 range.

Can anyone answer my question and giv insight on it?

they're probablyh referring to the 5-spd se....I don't see the auto doing it in 7.5 even with different gear ratios...

but if you're going to be spending money on your tranny to get better times, I would suggest a high stall torque converter.....the power on the 1mz kicks in at a fairly high rev, and a torque converter that stalls at 4000rpm will help you cut some major time- it will almost throw you directly into the power band

Hey Eye8, could you explain to me the high stall converters some more? I have looked into that as well, but don't full understand how it works and makes a difference.

Also, what is the stock stall convertor at?

Thanks

***Eye8Pussies*** · 03-23-2005, 07:13 PM

I would guess that our stock stall speed is somewhere around 2000 or so? I'm actually really not sure....never had a real reason to check before...

basically what a high stall torque converter does is let your engine rev more freely until the torque converter locks up and makes your tires move.

Now, for example, let's say our torque converter stalls at 2000, and our real power hits at 4000, the revs will slowly go up from 2000 to 4000 because there is already a load on the engine since 2000rpm.

Now if you had a high stall torque converter that stalls at 4000, the revs shoot straight up to 4000rpm at launch before a load is put on the engine.

Or at least that's how I understand it.

You can take a look at www.levelten.com for more info on their tranny upgrade and high stall torque converters.

if you want to ask questions about practical aspects of having a high stall torque converter, shoot tony a pm, as he's one of the few who have one

Thanks Eye 8, just wondering though, does toyota put the low stall converter on for engine/transmisson longevity, or simply to provide nice smooth shifts?

Thanks

***Eye8Pussies*** · 03-23-2005, 08:27 PM

probably the smoother shifts.....theoretically, I'd say that the higherstall converter wouldn't be any harder on the actual tranny except for potentiall the mounts because of jerking when shifting

I asked tony about it before, and he said that it gives a pretty harsh shift....I can't say tho...the only time I took a ride in his car, it was already boosted, so....I'm sure the jerk when the tranny shifted wasn't just because of that

I'm doubting they changed the final drive ratios. But either way, if your going to open it up and change the final drive, why not change all of the egars for the same cost and get a much faster acceleration through all gears? It only makes sense money-wise.

However I would like to see the stats saying it is .8s baster in a 0-60. For some reason I doubt that they changed the drive ratios of a Camry.

Also, high stall torque converters majorly kill your mileage (if that's a concern to you). My brother got one on his SHO and he lost over 80mile/tank because of it.
