I have a SIR-G swap in my hatch for those that may not know its a B18C and from what I know it has the JDM Y80 trans also. I hadnt really thought about it till a little while back I was showing off for some friends and decided to take off spining up the street and my car left 2 black marks for about 50'. I didnt originaly put the engine in the car so I didnt get to look into the input splines to see if I could see through them also I cant see if it had LSD stamped on the bellhousing. So does these transmissions have LSD stock?

 

I believe it was a factory option. If you got it unwittingly, you are one lucky bastard, as they're typically $250-300 more

 

I may be one lucky bastard hehe
