I just recently recieved my engine for my swap. Your average b16a swap in a 90 civic si. Nothing exciting here. My question is, it came with a J1 trans WITH lsd and an electronic speed sensor... a Y1 intermediate shaft, AND a b16a2 head! Whats up with this. I looked all over the internet and did a search here and found the only trans to come with LSD was the Y1. So whats up with this weird combo? Anyone have any similar experiences?

 

ttt? anyone??
