ok so i was looking at a FD2-R LSD and a DC5-R LSD and i see theres a difference is one better than the other? because im planning on getting an LSD i know quaife is good but too expensive for my budget well let me know which one you recommend thanks

 

well what are your horsepower goals? Because each has its strengths and weaknesses... I sucked it up and bought the quaife cause I'm supercharging the k24 in a little bit.

 

well around 300-350 hp thats my goal

 

It is my understanding that the sand cast housings are safe to about 300whp, after that you should look for a forged unit.

 

but which ones better i heard the FD2 is better so thats pretty much my question which out of the 2 is a better LSD?

 

they are pretty much the same.....same sand cast housing, same number of worm gears...The quaife and obx have more worm gears so they shift power harder......I Have seen threads where people have fit fg2 lsd's with the speed sensor rings as the a2 diff and bolted them into the a2 trans so there are no differance in fitting....You want something better? Try the wavetrac. With any worm gear lsd, you loose 100% of traction on ether wheel, the lsd acts like a open diff. The added parts in the wavetrac makes it so you do not get that or so I have read.
