My Differential (before and after welding)

[99SL2_Modder]

People always ask why I cna't do what Mopar people do with their open diffs...they unbolt 2 of the bolts from the gear, and put in a piece of metal. You'll see why I can't do that now.









Looks damn good, like the rest of the trans, for having 70k on it. No pin movement.

*edit*
I will provide pictures after the welding is done.

Looks to be in perfect condition, good work.

Every time I change the fluid in my rear diff, chunks of metal come out.

Good work? This is from the manual I bought for 75 bucks, lol. Can't believe how mint the inside of the trans was for such a low cost.

But, that diff is gonna be welderfied.

sounds like my Tahoe.....damn POS.

what's the gearing on that diff vs the gearing on the one you currently have?

This is a manual with 4.06 gearing. I have an automatic with some stupidlow gearing. I'm doing an auto to manual swap once I get the rest of the parts. This diff is just getting a welded pin so it doesn't grenade on me.

*edit*
Autotragic gearing is somewhere in the 3.55 to 3.73 range. The 4.06 will help a ton.

Looks similar to a DSM front diff.

I enjoy having the ability to turn, thanks.

RWD cars are fine to do that to, since you just can gas it to kick the rear out to make the turn, but fwd would put so much stress on the welds that they have a big tendency to grenade when even at 10mph turns.

You're welcome to compare it. Maybe we can start using DSM parts for our cars!

please post car specific threads in the appropriate place. i moved this one for you.

I just re-read what you said, and I'm not sure if you meant to ask if this was an aftermarket differential.

The answer is no. It's a bone stock manual differential. The only aftermarket differentials are Quaife LSD's which cost $1800, and have the same gearing. There's so little aftermarket for Saturns that we have to do our own thing. Mopar has their support from factory, just like most other manufacturers. Saturn has nothing. The ratio is something like for every 20 honda sale sites, theres 1 Saturn performance site. I only know of 3 off the top of my head that are straight saturn performance. Saturn Motorsports, Street Design Auto, and Saturn Performance Specialists. Plastik Racing is starting on more sales, but they're just some harder to find things.

I feel your pain, get into the bmw performance or worse, bmw FI and you'll cry.

best of luck with the conversion but I'm curious as to why you won't consider selling the sl2 and picking up another one.

[BlackBulletTSi]

If I'm not mistaken. Correct me if I'm wrong Clint. But I believe that he is putting in a SOHC tranny. There better gearing and stuff.

The conversion costs less than buying a new car.

Longer, really, but essentially, at 6500rpm, the 5th gear on the mp2 can hit somewhere in the 180mph range, while the 5th on the mp3 can only go up to 150-ish. And that's only 6500, whereas my car can rev to 7200rpm with a manual without fuel cut or rev limiter.

*edit*
not that I'm planning on going that fast. the second gear on the mp2 is good to 63mph@6500rpm. Meaning I can cruise around town in any gear above that and save hardcore amounts of gas. The taller gearing is for the turbo that comes later. A longer first/second gear will help get the power to the ground and minimize wheelspin...on paper...torque is a problem, but that's a whole different post.

I feel your pain on finding parts. Saab parts are just as bad, especially 9-5 parts in the US. Many 9-5'ers are starting to make their own stuff, I'll probably fab my own intercooler setup.

[themadhatter]

cheaper overall or just easier to do? I did the same with my own car, I just didn't want to sell it.

sorry, worded it poorly.


you said it's cheaper to just swap it out then to buy another one. I was just asking if the swap was easier to deal with rather then selling your car and buying a manual one etc.
