Diff options for GS400
#32
ive searched a couple times on here but didnt come up with any good, solid, resource...just mainly DIY install threads with random info....
im trying to figure out all the gearing/diff options that are available...what fits, what doesnt....what diffs, or complete rear ends from other models will fit, what ratio's they have etc etc. anyone know of a good online resource that has those bases covered? or should we hash it out right here and now???
lol, thanks

HAHA!! Yea its me Ramon so turns out the gs300 rear end i picked up last weekend wasnt a toyota/lexus rear end at all. i was in a hurry and just threw it in my car and then looked it over when i got home....not sure what it was out of. close, but no cigar. so now im on the hunt for another one...i hear Horrell has a couple sc rear ends...just need to call him.

I guess im a little confused here, is there a speed sensor in the Diff? or is all of the speedometer info grabbed from the wheels?
-EDIT-
Never mind me, just checked the sensor lineup on alldata and found out that I am indeed an idiot.

It's like changing the rear sprocket on a bicycle. The final drive ratio determines the wheel speed relative to the driveshaft. The GS300 has a different final drive ratio than the 400 and 430 because it has less torque. In a GS300, the wheels will spin 3.92 times for every rotation of the driveshaft, in a GS430 (I'm not sure about 400) the ratio is 3.27. If I had to guess, I'd guess that the shop installed a GS300 diff with the higher ratio, which would give you better acceleration but your RPM at a given speed will be higher.
