I have a jdm gsr tranny in my integra and have been seeing people say that the lsd that comes in them are chit. I will probably be around 500whp next year and dont want my diff blowing up on me. What do you think?

 

Replace it.

 

is the jdm GSR lsd bad for like 250HP or would it hold up just fine???

 

It should hold up, but won't work well when it gets heated (i.e. road racing).
