3.73 G80 price check...

I'm pretty close to buying an entire 1995 940 for the rear end, ac system, and squirter block. At this point, all I'm ready to change over on my car is the rear end. So, I figured that I'd ask how much for a 3.73 ratio G80 rear end? Of course, shipping is a no go, so if you have one in the New York area, please let me know.

If you know how much they typically sell for, please let me know.

-Thanks

EDIT: For what it is worth, please note that I have searched the for sale section for 'G80' and 'G 80', neither of which works. A search of 'rear end' comes back with a lot of stuff that isn't what I'm looking for.

Do you already have your eyes on a specific 95 940? If so, just buy it cheap..

Are you wanting the whole axle to swap into your 940, or do you just plan on getting the guts into your 240?

If you’re dead set on getting the later ac, the g80, and a squirter, it’ll be cheapest and easiest to just buy a parts car.

I’ve never bought a g80 by itself, but I’d imagine you could get an entire rear end for under $200. Just a guess.
 
G80 lockers with ring & pinion gears, 3.31 & 3.73

For significantly less labor, purchase a full 1041 rear end. ATL pullapart price is around $100 if your buy “without rear brakes/backing plates”..... I.E a naked rear end. Setting up a non LSD or G80 is not worth your time unless you desire to learn the process.

A late NA will get you a 4.10 rear with G80...... a near free +10% torque to the pavement

I've sold a few g80 pulls for $120 shipped. I can get it in a slightly bulbous large flat rate box (your success here will be hinged on how charismatic you are at the USPS counter)

The gear ratio in that 1045 axle will most likely be a 3.31. The first 3 years of the US market 960 wagons had 3.31 gear sets.

I usually sell G-80s with their ring and pinion set for $125-$150, plus shipping.

My 95 940 NA donor had 4.10 installed with a G80 (which I sold and fitted a real LSD :cool:)

I understand the early 960 rears did come fitted with the 3.31..... but weren't they open as opposed to G80?

and FIXED my prior post.... meant 1041, not 1045 DANA rear end.

For reference my 1992 960 has a 1041 rear w 3.31 & G80 locker as stock.

Also I would not want 4.10s for a street car with the small tires as it would be wound out on the interstate. Find an online speed calculator and do the math before going 4.10 so you are comfortable with the outcome.
 
^ Depends upon your gear ratios.

When I can find a Camaro / Firebird T5, I plan on putting in 4.10s. With a .63 overdrive and 25" tires, you're doing 85MPH before you hit 3000RPM.

So, yes, depending upon the rest of your system, 4.10 might be a bit much. It depends. :e-shrug:
 
Camaro T5 Gen4 numbers:

Gear Ratio Top Speed Redline
1st 3.75 39 6500
2nd 2.19 67 6500
3rd 1.41 103 6500
4th 1 146 6500
5th 0.72 202 6500
Rev 3.53 41 6500

Tire Size: 225/45/17
Diameter: 25
R&P: 3.31
MPH RPM in 5th
45 1500
55 1800
65 2100
75 2400
85 2700

FWIW in my C10 I have an S10 T5 w 3.73 and barely need 5th unless cooking on the interstate.
 
Not the Gen4 T5, which is the V6 option. Gen4 V8s got the 6 speed. The one I was referring to is the Gen3 V8 T5 with the 2.95 first gear.

More like this: (Gear MPH RPM)
2.95 39.97 6500
1.94 60.78 6500
1.34 87.99 6500
1.00 117.91 6500
.63 187.16 6500

Good highway cruising with the .63 5th. 86MPH at 3000RPM. Much more usable 1st and 2nd gears. This is the default T5 set of ratios in the calculator on the Tremec page that I linked above.

Mark G, what are you setting the car up for?

I figured you were after a Gen3 V8, which are getting hard to find. Check out 5speeds.com for the proper rebuild goodies. Def get the countershaft bearing support kit! Also take the time to set the input shaft play to proper specs. Bronze shift pads. Do it right while its on the table.

I'll be a little picky to help save you money...

1st between the two setups are the same.
2nd the Gen4 gets a little deeper at 67MPH for the stoplight races.

Basically with the Gen4 you can keep the stock 3.31 rear and save as the Gen4 is much cheaper than a Gen3 V8.

Also having owned a CTS-V with the T56 I can tell you that the deep 6th was basically useless unless over 70 on the interstate. With the deep .62 I suspect 4th will be wound out and then huge power dive on the 5th shift. Also 4th topping out at 117MPH is not that good if you have to dump a gear for a highway roll. With the Gen4 you can do the traditional 3rd drop for a highway pull.

And where in Vermont are you cruising at 86MPH? TX I believe it, but not VT. Heck here in VA I consider 75 tops for a sustained cruise.

You will have a lot of money in either trans by the time it is properly setup and ready to install, so just pick wisely for your application. And don't trust the internet, decide on how you like to drive a daily and have it match your preferences. Granted even selecting a T5 for high HP is breaking the internet already! LOL
 
Which other transmissions have the 2.95 first? The Gen3 V8 T5 is 2.95,1.41 versus the Gen4 T5 (V6) 3.75,2.19 first and second.

Not interested in stoplight races or highway rolls. More like twisty mountain roads.

I wasn't saying I would be driving at 85mph, I was just trying to illustrate the cruise RPM range. First through fourth are fun gears. At cruising speed (65mph), shift to fifth and save some gas at 2250RPM.
 
Yeah that works good in something like a 6 liter v8, not so great with a 2.3l banger. You're gonna have to shift to 4th every time 91 or 89 makes a little elevation change..


More like on 108 through the notch. I'm only on 89 maybe once a week and I haven't been on 91 in over a decade, I think.

The 305ci in the Camaro that this came behind made 150hp/240lbft as from the factory. Certainly reasonable numbers for a 2.3L with a turbo.
