DOES ANYONE KNOW WHAT THE GEARINGS ARE?

A FEW OF US HAVE HEARD THAT THERE ARE THREE DIFFERENT ONES. I ASK THIS BECAUSE I'VE GOT AN 82 BRAT AND AT 70 MPH

I'M TURNING 4000 RPM THATS WITH 185/80/13. WHILE MY BUDDY HAS AN 85 HATCH AND 175/70/13S AND HE DONT TURN THAT MANY RPMS. IF SOME ONE CANT TELL ME THAT BE COOL.

why are you yelling?

Damn dude, don't be so hard on the guy, maybe his caps lock is broke...man Erik, you are starting to sound like all the old farts on this board with 1000+ post counts....chill!

hey, josh, you got yellad at or the same things.

 

there is lots of postings about gear ratios, try the searchg function and see what you can find!

 

welcome to the board

the different rpm could be attributed to the difference in wheel size, but as a genaral rule, if the car is a manual its 3.9 and if its an auto or turbo its 3.7 rear axle ratio.

I believe there were two different 4-speeds used in the EA81 series. The earlier models had a 4th gear that was geared lower (more RPM at a given speed). I think it was in the 1983 and later EA81's that the 4th gear was a lot "taller" than before, giving less RPM.

Actually - 3rd and 4th are different. And yes - the 82 4 speed's have the shorter gearing. It's great for off-road when you lift and put on big tires.

Yup, when I thrashed the 4spd in my Brat (82) I replaced it with one from an 84, serious difference in the top speed, 82= 65@like 4K 84=65@3.6K. As far as I can rember of course, your results may vary. I almost never use the top 2 gears offroad, so it wasn't a problem.

Ah - yes I meant it's great of an off road RIG, with big tires. Cause you can still drive on the freeway.... or you install a 5 speed. Either way.
