Because as One320B just said I'd have to have everything else i.e. the half shafts, driveshaft and pumpkin because the TII rear end is bigger.

Thank you. I think I'll go with this. Hahaha. All these other posts are beginning to confuse me.. because people are contradicting themselves. Thank you for your help.

I am not contradicting myself, neither was anyone else.



I am suggesting you save your money and efforts and apply them towards a TII rear end set up, you can usually get a whole rear end with halfshafts and driveshafts around $350.



if you want to stay with NA stuff your question was answered correctly by everyone except one person.

Well this one guy only wants 65 for an S4 LSD so I think I'm going to buy it. I would assume the TII rear end would be a little better for holding power.. but as of right now I'm kind of short on cash so I don't have 400 to spend on all that stuff.

why not just save your money until you can do it right, why bother if you are already running the car with a non lsd rear now.

Because then I'm also going to have to buy a new driveshaft. And from what I've heard not just from the forums but other people, the N/A rear ends are built pretty well, and they're able to handle a good amount of power. And right now, my car put down a little over 400rwhp and about 300rwtq.. so if the non lsd rear end can handle that I don't know how much more it would be able to handle, I think I might be pushing the rear ends limit, especially when I'm only running 14psi for when my motor is build for far more, and my MicroTech can go up to 2 bar.

400 hp and you cant afford a $350 TII rear end set up? For the $350 you can usually find a rear end AND driveshaft.





anyhow- as long as you dont launch the car from a stop too much it should last a little bit.

Then if you do blow it up what you have will be worthless at that point.

Now you could sell your custom driveshaft to offset some of the costs of a TII set up, if and when you do blow up the rear

end hopefully the driveshaft does not get damaged.

Haha. Yeah. All my money went into the motor, the car itself isn't all that great, the body is straight and so is the interior, but the exterior is just primer. The mechanic I paid for the job, kind of did a half ass job, so... he did everything to get it running. Don't get me wrong, he does good work, but all the money was spent on the parts to keep the motor together and to make the power.

still- what good is the power if you cant put it to the ground

Which is why I was trying to get a LSD to put it to the ground a little better.
