differential swap or not

[kkiepvvessau]

i think the best set up is used the supra auto TT differential. the ratio on the Auto tt LSD, it will launch faster than the manual LSD. my friend tried the GS300 differential, It fix perfectly but lack top end. the 93-98 SC300/400 suspension parts are mostly the same but i'm not sure about the Differential bolts. The IS300 is different set up and the ratio is suck.

Well your diff has nothing to do with top end capabilites. That would be the type of gears you have in your tranny. All the diff does is make wheels turn thats all. It takes whatever torque/power the tranny makes via the engine and is transfers that power to the ground. So your whole concpet there is a little misguiding IMO.

And I dont know how the IS300 is a different setup cause its the same motor and tranny as the supra it just has a little better technology than a 93-97 vehicle. If anything the IS300 should be better cause its like almost 10yrs newer therefore newer and better technology is involved in that car. Is this making sense?

due, you know what you talking about?

well sometimes i do sometimes i dont. However, I am going to be fair about this. I am going to tell you the same thing I tell everyone who doesnt agree with me.

Please if you can refute anything I say by posting a link with facts to back your side up then I will gladly admit I was wrong. I did this to another guy on the supra or bmw thread and I have yet to hear from him. So now the balls in your court.

the differential does more than just turn the wheels. people spent thousand dollar swap differential to get the car faster. read this and you might understand better http://www.z1motorsports.com/PDFs/TT...earendswap.pdf . i'm not a smart guy . i just wants to share about stuff that i know.

well he was pretty much right...though the top end part i did not know, but wut he said about putting power to the ground is correct, since thats what a diff does and allows the wheels to turn, the diff just makes it easier to transfer the power to the wheels without losing it all through lost traction

Well your talking about converting a single wheel turning diff to a LSD(aka limited slip diff) or a ATB(aka automatic torque biased diff). These diffs are also bullet proof none the less. Your stock gears are much more brittle than a forged diff. So when you get a cusco, or a quaife you are able to downshift at higher rpm's much more smoothly and effortlessly. And they make both wheels turn at the same rate. Stock diffs do not do this. This is why they cost so much. You are paying for precision machining and anytime you deal with that your talking some coin. I payed all together with instalation and new spider gear about 1500 for my quaife diff. And it was money well spent.

So again, the transmission transfers power(hence the terminology trans-mission) its mission is to transfer power. And the differential just takes that power and turns the wheels. I guess you could say its transfering power from the tranny to the ground but the tranny doesnt create power it just transfers it. Now the correct analyzation would be that the diff distributes(not transfers) the power to the wheels. I hope that helps a little.

distributes...transfers....same idea...but yea....putting in a quality diff is not gonna be cheap
