Zcarsource or WhiteheadPerformance Rebuilt differential $1700

Hi All,

I am between a couple options. Rebuilding a diff or buying a rebuilt one.

A differential rebuild kit is roughly $500 then the labor to do it is probably (I’m guessing) around $500. That’s $1000. There’s no core charge in purchasing a new diff so I could sell my old one for $200. That means I’m paying a $400 premium to just have a rebuilt one mailed to the door and not deal with local inexperienced rebuild places.

If I buy a rebuilt diff from WHP its $1700 for an open long nose r200. From Zcarsource it’s $1600 (with a 90 day warranty). I was told I could pick 3.9 or 4.11 ratio for the rebuild. I’m going to go with 4.11.

This seems like a big dollar decision whichever way I go, so I was hoping to get some insight from you all. Also, if I can trust that these places to even send me a rebuilt one and not just mail me one hoping it works and charge me for a rebuild that they didn’t do. How would I know?? Zcarsource seems like a good shop; i talked with them o phone. I’m not impressed with whiteheadperformance as much.

Thanks!

might be a little easy maybe to just use the diff you have in your car right now, or try to find a whole car in salvage yard and remove a diff from that.

Or perhaps a Subaru WRX STi LSD would be an option. It would still be over $1000, with the did stub axles to fit.

I don't know about their differentials, but I had Whitehead build a 2.8L motor for me.
Was it inexpensive? No.
Did it take a long time? Yes.

Am I pleased with the work? Very much so!
One bit of advise - DO NOT even consider driving to Toronto to pickup the finished diff. Let them ship it to you. Border customs is a total nightmare!
