Ok im picking up a 88 NA FC LSD to install in my S5 91 NA FC, and i have some questions since i did a search and couldnt get any answers.

1.) Is it true that its a direct bolt on and that i can use my NA drive shaft and half shafts?

2.) Do i need to buy any aditional parts? I have the LSD assembly with the pumpkin.

3.) Im planning to do a turbo swap in the future, can i install the driveshaft and half shafts of the Turbo in the N/A LSD or do i need to buy the Turbo LSD?

4.) What parts do i need for an LSD rebuild?

5.) Finally could someone point me to a write up for the installation, rebuild and the FSM manual? I cant find it anywhere =(

Thanks for the help and patience but finding answers with the search is like a needle in a haystack =(

 

1. yes

2. no

3. you'll need the turbo driveshaft, diff, and halfshafts, or a conversion driveshaft for the t2 tranny to work with the na diff

4. bearings with races (6), cone springs (2), and clutch discs (4)

5. Removal and installation of the diff is fairly straightforward, but can be time consuming. Link to FSM--> http://www.teamfc3s.org/main/factory_service_manual/

 

Thanks very much, so my only problem would be coming up with 400$ for a drive shaft. Also where can i get the LSD parts from? Can they be ordered from an autozone? How much would it cost for the parts? and what tools do i need?

 

cone springs and clutch discs can be had from mazdatrix http://www.mazdatrix.com
bearings you'll be able to get from your local auto parts dealer. Once you have the diff apart, take the bearings and races to autozone or wherever you guys get parts, and they'll be able to match them up

 

Ok let me see if i got it right, accourding to Mazdatrix i need, 2 Cone Springs, 4 LSD Disc w/inside pins, and 6 LSD Disc w/outside pins?

Damn but thats almost 200$ of parts!, so they costs as much as the LSD?? Can you put Turbo parts on the NA? proly stupid question but would that work?

Im looking at this link: http://www.mazdatrix.com/G8LSD.HTM

 

Wow the parts on my shoping cart are $363.76, WTF i only paid 150 for the LSD! Is it me or the prices in Mazdatrix are insane?!

 

How much horse power/torque can an NA LSD take?

 

Read the FSM!
It tells you exactly what you need to measure and each parts wear tolerances. Disassemble the LSD unit and mic the parts before you come on here and complain. You won't need $360 worth of parts to rebuild the LSD unit.

 

Whos complaining? im taking the LSD apart tommorow, what im doing is not rebuild it completely just changing the parts that dont meet the clearances instead of buying all that **** from Maxdatrix, i still think their prices are insane, it makes sense since theres not many after market manufacturers for the FC.

 

No, The N/A is a smaller size then the Turbo by 1 inch. I think 7 N/A 8 Turbo but I may be wrong.

 

By any chance do you know how much HP/Torque the NA LSD can handle in comparition to the Turbo?

 

So far I am putting out about 250 to the wheels in my turbo swap w/ na diff. So far so good. Then again, I am not an aggressive driver.
