Cheap way to have posi traction?
 

From my post you all see im still waiting on my car to be shipped from Jersey so im doing a lot of research.What is the easiest way to get posi in my car?I know GSL-SE rear is the way to go but that is costly.Any ideas?

Broke? Weld the diff, more safe for you down there without the crazy snow im getting up here!

i was thinking that but i didnt want to get laughed at.Is it hard to do and most of all safe?

Where at in L.I? My parents live in Medford.

Ah im in Rocky Point, not that far from Medford at all. Well with welded diffs if you know what your doing it isnt that hard. (havent done it myself but seen it done and have owned a fc with a welded diff) There are pro drifters who use welded diffs, its not that uncommon. I would be slow and smooth in wet conditions tho...

EDIT: I have a friend who has welded a few without a issue yet, But i hear in time a welded diff can shatter?

yehh i guess if you beat on it hard.Only mods ihave is Racing Beat carb and intake Msd coils and a header.

Go for it, cheap and easy as i seen. And it shouldn't take that long to save for something proper. Also my friends who use the welded diffs have 200- 350rwhp and they all been holding up for around a year now with plenty of abuse.

thanks its late goin 2 bed be carefull with all that snow

Why do you want LSD? My 1980 has an open diff and it is fine. It is very safe in the rain compared to my 1984 with LSD. Unless you are running hi horsepower, I would spend my money and time in other places.

Also if you want an LSD (or both tires pulling at the same time) don't rig it by welding the diff.. Save a little $$$ and find a used LSD and install it.

welding the spider gears kills the cars ability to corner well. it will also wear the rear tires faster, i know. just going around turns, the inside tire is turning the same speed as the outside tire. a U turn greatly proves this.

I paid 300 bucks for a complete rear end out of a GSL. Same lug pattern as my GS, so no hassle there. Got me rear disc brakes too. And the handling was greatly improved.

(I don't understand the references to poor handling with LSD)

Don't be a cheap ass. It doesn't cost much to replace your open diff rear end with one equipped with a LSD. Plus, an open diff isn't too bad.

my second RX7 had it and my recently totaled 4x4 have posi I just like hanging my ass out sideways lol

So you're worried about the $300 it will cost you to get your hands on a LSD rear end but you don't care about chewing up $300+ in tires every year in your other cars? I don't understand the logic...

i bought a complete GSL for 200 so i could have the LSD out of it. just look around and you will find a deal.

since you put it that way i guess it would e better to do it the right way.Iknew a lot of people who did that to muscle cars or i should say wanna be muscle cars.Thank you for the eye opener:nod:

No not yet.Once i get the car i need to go over it with a fine tooth comb.Clean it up and stuff.Just thinking ahead of myself[IMG]http://i477.pho

Since you live in Georgia, you are very close to Respeed (you lucky bastard!). If you have any plans to upgrade the suspension, brakes, or damn near anything else, they will be the ones you want to talk to. They are always very happy to give advice on setups as well, and have the years of experience necessary to give that advice. Billy spends a lot of time on this forum too, which is nice (Bwaits_).

after searching i need a 81-83 gsl lsd because of flange size

For what it's worth, I found a GSL rear end in a junkyard for $100 around here, so they're not too incredibly expensive.

if you are using your car as a daily driver, i deffinitly wouldnt weld it. but if its just for sport (like drifting as someone mentioned above) its a very cheap, easy and surprisingly reliable way. plus they dont wear out like clutch types can, they just explode. which, lets be honest, is waaaaayyyy more fun!

A welded diff is fine on a race car, but on the street it will get annoying. The tires will skip and chirp every time you go around a corner slowly, and will make you miserable if you ever have to push the car around (the car will just stop as soon as you turn the steering wheel).

As for reliability, My dad's old ITS Z car won LOTS of races with a welded diff (and cut springs/Tokico Illuminas) and never had any drivetrain issues. The welded diff helps with corner exit speed, but can and will make the car understeer more.

And as for my car, that thing would one wheel peel every chance it got, on a stock 12a. On ramp? Inside tire spinning, attempt going into a corner at any rate of speed, and accelerate out with any throttle? inside wheel spinning, launch the car? one of the wheels is going to go crazy.

I ended up buying a GSL parts car and stripping it of parts, cleaning then up nicely, and installing them. Now that I have done all that, there are like 5 GSLs complete with rear ends in my junkyard. :banghead:

It did clean up nicely though... :nod:

I broke a tooth on the spider gear in my one wheel wonder 65 Barracuda. I welded the diff, twice, out of necessity until I could find an lsd one. Just to get the diff, I had to buy the whole car. Now that was a fun car, diff issues aside. Back then it was classed as a sub-compact, even though it's a tad bigger than the 7s and much much bigger than the 73 Civic.

Where i live there is No RX7s in the junkyards.So have to search abroad.

Any GSL LSD will bolt in but 81-82 had small flange and 83-85 had large flange and 84-5 had big bearing. But get any of them and you can get a new drive shaft to fit.
