out of those, the itr is the only one with lsd.

 

Well, the only US market tranny that came with an LSD is the ITR tranny. Unless you feel like trying to track down a JDM B16 or GSR tranny with LSD. Your other option, of course, is to just purchase an LSD and install it in your tranny. The downside here is downtime on the tranny, plus you'll have to buy a new ring gear if you get an ITR LSD. You could go crazy and invest in a Quaife, but plan on paying about twice as much as you otherwise would for a new ITR LSD.

 

itr, because of lsd.... Wish i had enough money for one....

 

but wich one would fit right in with out no problem the itr jdm or us
