I've got an S5 GTU can I do a direct swap for the S5 n/a LSD rear end? What about an S4 LSD rear? Do I need to change halfshafts for any of those swaps?

Will all n/a rear ends swap without having to change halfshafts or is it all s4 n/a rear ends are interchangeable without changing halfshafts, and all s5 n/a are the same but you can't interchange between the series?

 

a s4 or s5 turbo lsd wont fit you would need the halfshafts the s4 and s5 non turbo lsd will fit

 

I swapped in the S5 N/A LSD rear end (from the GTUs model) into my GXL, and yes it is an exact replacement as long as you have the entire assembly including the output shafts. The N/A rears are all interchangeable.

The only thing you have to watch out for is that the output shafts for the GTUs rear are unique to it, and the driver's and passenger's sides are not the same. After the output shafts are plugged into the rear end, it has the same size as all the other N/A rears (no change to half shafts).

I made the mistake of buying the GTUs rear that only included the nose section, so I had to reuse the rear cover from my stock rear and buy the output shafts from another forum member.

 

All NA rearends swap into all other NA cars with no other changes. ALl turbo rearends swap into all other turbo cars with no changes. You just cant try and swap NA and turbo parts.

 

Well im currently asking around for a gtu or gxl diff. So i shouldnt have any problems putting it in my '86 base. Right??

 

<beats head against wall...>

 

Give up Kevin, they either will understand what are you saying or will try and find out later

 

I got a s4 gxl rear end. 300 bucks

 

That's not bad. I paid $300 for an S4 Turbo LSD rear hub to hub but I had to go to upstate NY to get it. He did throw in the front brake setup for free, but I ended up buying new stuff anyway.

 

man I was just kidding, i'd sell it for 125 if tofu doesn't get the car out first.

 

Damn, even I picked up on that one. Heh, althought I can't say I'm not guilty of overlooking the obvious one of two times .

 

PM'd you.

 

i also have an s5 gtu (1989 so its base) and i want to swap in an LSD rear end... what am i looking for? s5 gxl ?

i have heard so many different things i want to clear this up right now

 

86-88 gxl 5speed, 88 gtu, or 89-90 GTU-s 4.33 (ultra rare).

 

I understood the first time, I just like to clarify certain things before i spend money even if it means i look like a fool on an internet forum. My bad.
