Default Mechanical question, help! Ltd slip diff!

I have a 2.0 Boxer Diesel Subaru Impreza, I've seen in America there's a rear LSD

http://www.rallysportdirect.com/Cusc...-WRX-2002-2011

My question, would this be valid for the diesel version? I have little idea about mechanics but I know more or less what a LSD does, If it doesn't work with my car, could somebody explain basically why it won't?

Many thanks!

Carlos

Cusco is Japanese.
I think fitment depends on what differential you have now, otherwise you might be looking at swapping the whole unit.

I had no idea, I have the standard rear differential, I don't understand by "swapping thw whole unit" What does the whole unit consist of? Excuse my poor knowledge of mechanics

can you use google or another search engine to see if you can find some of the answers???

it will almost certainly be cheaper and easier to change your entire rear end with one from another subaru that has the lsd in it

you just have to make sure to match the final drive ratio

I think it's a good idea, trouble is finding one My car is six-speed diesel, wrx are 5-speed, only the sti's are 6 speed...I really wish my invention could come true plus sti's are R180 and the wrx are R160

Thanks for the idea anyway!

id bet that your vehicle uses an r160 rearend just like most of the rest of the 5speed cars use

the transmission is irrelevant...the rearend and its final drive ratio matters

take a picture of the rearend and post it...use tinypic,com to host it

you need to find out what rearend is compatible and what ratio yours has

post that here....

the transmission does not matter

Right!? IMO the younger generation has too thin of skin. Getting teased or learning how to give and take isnt something they feel worth learning.

Now learning our beloved Uncle Scotty and his lovingly pointed replies may be a whole other task altogether!

Not to get too sidetracked. I think both of you guys are right. Too thin skinned and wanting everything spoon fed.
I've been on here since 06 and a member since 07 and I roll my eyes on a daily to some of these threads and posts. I can't understand how U.S. does it.

I thought those were turbo 2.0 diesels? 240hp/420tq hence the 6spd only avail. And apparently the r160 out back!

Hi! I have more information, final gear ratio is 3.900 for the Subaru Impreza 2.0 Diesel
Final gear ratio of 4.444 is for the subaru forester 2.5XT and Outback 2.0 Diesel, so I was wrong, dong!!!!
Here's the technical specs from Subaru's home page
check out the link below:

http://www.subaru-global.com/11impreza_spec_5d.html#02

The 2008 wrx and sti (2007+) are 3.900

Got it from this thread below!

http://forums.nasioc.com/forums/showthread.php?t=181343

Am I near the holy grail? Still waiting on the photos, gonna give the mechanic a call

Thanks for the support!
