I have two Acura RSX's, and I am curious if they have a factory installed Limited slip differential. I have a 2003 Acura RSX Type S, and a 2004 Acura RSX base w/Automatic transmission. I am just curious if anyone knows if either has a Limited slip differential or not. Also if they dont have one, I was wondering if anyone knows where i could get a kit or something like that for both. Any help would be appreciated.

 

No LSDs on any K-series engine thus far except for the K20A in the JDM only Integra Type R. You can sometimes find them for sale on eBay... expect to pay 350-400 bucks.

 

The auto base RSX will be impossible to find a LSD for - the only cars that auto Hondas that had them were the ones that came like that from the factory but they stopped doing that.

For the ~approx. double the price of the ITR LSD, you can get the Quaife - it has a lifetime warranty and can withstand the abuse of high hp applications.
