April 17, 201213 yr so im figuring out what the gears are in the transmission, and in the rear end in my ea82 4wd manual transmission. does any body know? im sure many of us would like to know so we can modify are subes further
April 18, 201213 yr Check the Ultimate Subaru Repair Manual. I posted a chart there with pretty much every EA8x transmission listed.
April 18, 201213 yr I did the work for ya too... and I was right... http://www.ultimatesubaru.org/forum/showthread.php?t=84798
April 18, 201213 yr Author ok awesome! but what about the rear end? or is the final drive gear ratio the rear end? Edited April 18, 201213 yr by wilcox
April 18, 201213 yr Author ??? huh the diff cant have five gears, i dont get what your saying, are all of the transmission gears added?
April 18, 201213 yr Author ok i see what your saying, because it is a transaxle, the diff is in the transmission. so the final gear ratio 3.9 is what the front and the back diffs are, but then they also show the other gears
April 18, 201213 yr Well... The 5MT on the FWD (2WD only) Models has very Long gears... that makes 'em to be at very Low RPM's on High Speeds, but I Don't know the Final Ratio... Sorry for Hijack the Tread but does anyone has that info? The Chart posted on the Above Link only covers the 4WD models. Kind Regards.
April 18, 201213 yr Author i just wanted to know the gears in my car witch is dr 4wd, and i found them. im curious to see what bigger tires will do to my highway speeds, and where it puts my rpm at what speed so i know where to drive in my torque range. witch is about 2700 to 3700 rpm

April 18, 201213 yr Actually, the peak torque doesn't start until 4200 rpms. 2700-3700 is a good cruising range, but not really the heart of the "torque range" +1 I shift my car at 6K when Im going somewhere "hard" because it when I shift into the next gear (usually 2nd or 3rd) I start at about 4K and it just keeps on pullin!
April 18, 201213 yr Yupp 1986 Subaru GL with weber carb on an EA82... even with a HG leak and I still get some pretty amazing pulls.
April 18, 201213 yr Author even though the redline on the tack starts @ 5ooorpm? i tried shifting at 5k once and you can hear it loose power and "whine out" doesnt that bother you that its bad to wrap it up that high in rpm
April 18, 201213 yr Im pretty sure mine starts at 6500... Ill check when I clean him out... But if I try to drive at 6K rpms (like hold it) I can feel the loss in power, but under hard acceleration, I feel it pull the whole way... could be the Weber that provides the extra boost... but soobies love to high rev...
April 18, 201213 yr Usually I Shift at 4K, but I have Redlined my BumbleBeast during Speed changes on certain circumstances when accesing to a fast Highway is Needed or similar situations, that EA82 Weberized runs Awesome at Higher RPM's without any noticeable loss of power, and gotta Love that Boxer Rumble on Full Throttle! Redline Starts at 6,500 RPM's : http://www.youtube.com/watch?v=Pz56wdwKDrA Kind Regards.
April 18, 201213 yr Look at the Above Posted Link, is a Video, the RPM's gets up to 7,500! Sorry for Hijack the Thread.
April 18, 201213 yr Look at the Above Posted Link, is a Video, the RPM's gets up to 7,500! Sorry for Hijack the Thread. Ive shifted there by accident once... guess I thought I was driving an auto or something cuz I looked down and was at 7500 in 2nd gear and shifted into 3rd and remained on the gas I had no idea they could chirp tires into 3rd haha Edit: back on track, Wilcox, what set-up are you running? year/model and mods?
April 18, 201213 yr Just want to say thanks for the link to the list of D/R trans gears ratios! Any way to tell a turbo 5 speed from a non turbo 5 speed by looking at it? Spline count, clutch type (push/pull), anything that clearly sets them apart?
April 18, 201213 yr I knew where the valves would float on all my EA82s. my '85 was about 6200 (tired motor was tired) the others were all more like 6800ish. not that bad for it.

April 19, 201213 yr Author +1 I shift my car at 6K when Im going somewhere "hard" because it when I shift into the next gear (usually 2nd or 3rd) I start at about 4K and it just keeps on pullin! i researched it and it depends, with stock components the peak torque comes in @ 3200rpm and peak power @ 5200 rpm. but that is also with the craptachi, so maybe the weber makes the difference. http://en.wikipedia.org/wiki/Subaru_EA_engine
