I did this a few years ago and broke both drive shafts at Santa Pod on my first run !!!!

There's quite a bit of discussion about it on hybridz.org. Essentially, you need the 27 spline custom output flanges sold by Wolf Creek Racing in the US, which will allow you to bolt up the Z half shafts. That is the only plug and play solution. $500 for the pair. Then you need to swap the input flange from the Z diff to the Subaru one. After that, it's a straight bolt in.
I've been giving this one serious thought too as opposed to swapping to an R200. Less clearance issues with my exhaust in keeping an R180, and an easy way to go LSD. Main issue seems to be finding a reasonably priced 3.9 subaru R180. The couple on eBay are twice the price of the 4.444 versions. I've only been browsing though so should maybe speak to some of the various Subaru breakers.

One change is that Wolf Creek Racing now do a full kit at $900 or $500 for just the axels!
I want a LSD in the white one, but for casings etc to remain as stock as possible.

I did get a price for using the complete Subaru drive shafts, remade with 'unbreakable' shafts, so they'd slot straight in and bolt the the standard hubs/drivetrain. A very simple fit and forget solution.
However I didn't want the hassle/cost of getting a few sets made than have them sitting round for years till people came round to the idea that its a great solution!

Just seen this, just had a look at the wolf creek one's, shouldn't be a problem to make some of those up, I will try and get a price for some 4340 today and see what I can do

Might have been me, I had one of the 1st WCR drive shaft/CV setups and the quality was shocking, I had to remanufacture nearly everything.
I had the shafts done by elite racing transmissions as the WCR ones were like chocolate
The CV joints were nasty so I used some GKN motorsport ones
The only bits left are the adapter flanges and the boots
Other than that its fantastic
But bear in mind the splines shafts have to be machined, splines cut and then hardened so 250 per pair
The CV cost around 150 - 200 quid a set
The boots etc another 50 - 75 quid
So nothings cheap ehhhh
All in all
If you can do some complete kits minus the donor diffs, I am certainly interested, and I guess John is too.
Being able to go back to stock is important to me so I don't want to have to butcher any of my original parts to achieve the swap.John, what is the blue beast running?

The blue car is running the z31 setup with wolf creek axles and crommoly Stubs. They are developing a bit of play in the cv's though. Probably not an issue but its increased from when I fitted them. Was using 280zxt with homemade companion flanges for a couple of years but I had to be gentle off the line as I kept snapping the axles. If I was to do this again I'd go for an all new setup and make sure I could get parts off the shelf (CV's) if I needed. The new Z setup doesn't need to be extreme so I'll stay standard for a while but I do want an r180 LSD, hence the start of this thread.
Scooby diff finally fitted but will be a while before I get to drive it.I have left the propshaft flange on and I am looking at getting a custom prop made to match as I keep finding info about the flange swop being preloaded which puts me off .
