88' T/A Swap Out

In the beginning stages of looking at swaping out my 10 bolt rear end (not original, blew the 9 bolt up) and putting in a strange s60 rear end. Looking to hear from people that have done this swap out themselves. I know I have a couple of hurdles to get over, but look forward to being able to plant 600 to 700 horse to it and not worry about the rear end blowing up. I believe I am going to have to come up with rotors and brakes on my own (hoping strange would supply them in a kit), I know what I currently have on the car will not work with this new step up...any recommendations on what to purchase as far as brakes and rotors are concerned? Secondly, strange indicated that I would need to get a different length drive shaft. Any ideas here? I currently have the 700R4 that has been modified, but thinking about going with a turbo 400 instead for more strength. I believe the over length of 700R4 is different than a turbo 400. Any feedback would be great. Thanks.

 

If you have current PBR 10 bolt discs you might try converting them. I know everyone says they don't fit, but I saw a thread awhile back that a member did convert them over.
Here I looked it up:

As for driveshafts I found this over at Spohn.net:
While you can have driveshafts shortened and rebalanced. It doesn't make any sense to go with a stock driveshaft that can't hold the stress. Not to mention the S60 should use a 1350 joint which would require a conversion u joint anyway. Various places sell them. You could look up Spohn or Denny's Driveshafts.

Being that Spohn lists turbo 400 short and long driveshafts seperate than the stock transmissions I would say yes different lengths.

That being said maybe it would be better off if you did want to switch transmissions to do it with the rearend. It would kinda suck to buy a $400-$500 driveshaft use it for awhile, then buy another different length or have that one shortened for additional cost after a transmission swap.

700-R4s are able to hold the power range you are looking at if they are built properly. Mine is a very old one at least 10+ years but is good to 550 FWHP. Newer models go to 750 FWHP.

 

Strange should be able to supply the drive shaft too. If you put the correct housing ends on the 60 and the axles are made correctly you can use your brakes on it. Talk to them about it.

 

Fireturd350: thanks for the info! I will be talking to strange shortly.

 

what about the strange 12 bolt? is that any good for the same power levels?

 

Since 12 bolt is only 8.8" something ring gear it would not as strong as the S-60 with the 9.75" ring gear. I saw info over at Spohn.net they said 12 bolts were fine for 700 RWHP or less.

Another thing with the 12 bolts are the torque arm bolts. You need to verify you have enough thread engagement there has been events where the bolts do not engage enough threads when using an aftermarket torque arm due to the thicker bracket and then they will loosen up over time. This can cause the torque arm to come off of the differential and as you guess a bunch of damage. I don't know if this is still an issue with the S-60.

It's interesting you brought this up as I just saw someone had a Moser 12 bolt on eBay with an unbreakable wavetrac posi unit ($800 upgrade). He canceled the auction and then told me he would let me buy it still if I paid him more than what he originally listed on eBay.

 

The S60 is stronger, and also heavier. The 12 bolt is more than enough in most cases.

 

I want a max of 600 at the flywheel. I want the car to be fun as **** to drive, but not so over the top I can only drive in straight lines hahaha.

 

Moser says their 12 bolt is good to 700 HP. You can get the 12 bolt wiht 33 spline axles. The S60 will have 35 spline axles.

 

isnt strange better than moser though?

 

That is more matter of opinion...depending on who you talk to, I'm sure both have pros and cons.

 

Just different aftermarket manufacturer company. Both are major names. It's up to you to do the research and read reviews to make the decision. I believe the backing out of the torque arm bolts were on the Moser units but I can't remember for sure.

For 600 HP at the motor a 12 bolt should be fine.

If you wanted the S-60 it would also work, but you would have a little more weight like noted above and larger spline axles. It depends on the application a normal street/strip car probably won't mind adding an extra 20 lbs (heck I have over 200 lbs of stereo crap in my car at all times), but a bracket racer looking for every weight savings might.

 

There is one thing that I like much more about the Moser rear end than the Strange rear end and that is the housing ends. The Moser housing ends allow you to use a OEM Ford type axle seal, where the Strange housing ends rely on the sealed axle bearings and a O ring to seal the tubes. I've seen way too many leaks with the sealed bearings and O rings. The OEM axle seals almost never leak.

 

ew ford :/ lol

 

but that torque arm problem could be fixed by longer bolts could it not?

 

Yes, they recommend longer bolts and loctite when using an aftermarket tq arm.

I want BMR suspension parts.

 

will I still be able to do burnouts with a wavetrac?

 

Yes, the Wavetrac is probably the best differential out there right now. Problem is that it cost about $400 more than the others.

 

I don't really mind. Just like the T56 I want is rated to 800ft/lbs, more if I swap out a pump or something. I'd prefer to not be able to break anything without trying to. I'm kinda **** that way haha.
