well those are guesstimated stats of power but i plan on running 15psi with gt30 turbo and was wondering if i dont launch my car at lights at all but i do would occasionaly drive hard on highway would my diff b done for?? i plan on upgrading it by possible cryotreating comptech diff or searching on where to get a R200 diff with inline pros upgrade kit is that over kill??

 

You should not have a problem with the stock differential for highway pulls as long as you maintain it. The launch is the real killer. I would just try not to slam it into gears with that much power you can shift easy and still kill!! lol

 

As long as you don't launch, stock is fine.

 

my diff broke shifting from 4th - 5th

 

thats crazy

 

wow that sucks so im guessing it kind of hit or miss with this. i have been maintaining it so ima just have to drive a lil more careful

 

Had my stock diff cyro'd and so far (knock on wood) no issues. How much difference the cyro makes i really couldn't say but since i had the diff off the car i figured it was cheap insurance. I'm making around the range you're talking about. I don't launch too often (what's the point, you get no traction) so figure that into it.

 

Im running a stock diff

 

i thought you had an r200?...

 

that is a stock diff
