parts are in. Just waiting on my press!

UPDATE: Diff came in Saturday and Half shafts Friday. Huzzah! I ordered a one ton arbor press from Harbor Fright… So we will get to work soon on cleaning polishing and painting.

I forgot all about courtesy! Thanks for that research, I am going to get 8 new bolts then!

I have a spare diff in my storage unit, so I may have an extra set already...Thanks! I just wanted new ones... well, just because...

My only thing I have to source is the pressed in studs that need to fit into the output shafts that WCR sells. I could take the ones off my old Diff, but I would rather install new ones. Anybody know a source of said studs. thanks! parts should start arriving friday or monday.

Well truth be told an OEM stock 240Z really does not Need a LSD. I am not sure I even still need one with the sticky 205 rubber I am running on my car. But it is sort of part of the package, so I welcome it, but I am not sure it will be a dramatic difference. Also, this will finally give me an excuse to install my RT Zsonthebrain diff mount as well. So a lot of things are going to happen once parts start to arrive. Kudos to Todd at Wolf Creek by the way. Shipped it out the same day I orderd it. Great service.

I got the STR2.8b In fact the pic on his webpage is my engine!

Jeff G, Your points are valid, and perhaps I did not find the best solution, but I think a factory set up LSD form subaru (my favorite car company, so I am biased) may prove more robust than anything I can set up in my garage. HOnestly, I never even heard about OBX until right now. But I went with what makes me feel comfortable. I trust Subaru, I trust Wolf Creek Racing, and I trust myself to put those together.

It exists, but I am actually using a stock B type shifter in my car. I had to trim the OEM 71 console a bit, but it works wonderfully and you cannot tell I made the cuts.

Well I can start out with the 3.90 as it is, and then if it gets too bad, I can install a 5 speed. I already have the tunnel cut, and the console modified to accept the Type B. So it should be a breeze. Still I mostly just put around doing car shows locally within 20 miles. So it may not be too bad. The occasional track day as well. Still the new diff may make my dieing tachometer a bit more of an annoyance. Time will tell. I can see mostly good coming from this.

I am not sure buddy. I have not finished this mod yet. I have just ordered parts. UPDATE: Wolf creek half shafts are ordered and on the way. All parts should be here in about a week! When I get them installed I will see what kind of mileage I get Ray. But I bought this ratio with the intent on one day maybe putting in a Datsun 5 speed.

actually no it is not sir. The real reason is that my diff has leaky seals, and has always had a bit whine. I figured if I had a choice, I would love a LSD and a bit higher gear ratio (like an auto 240Z rear end). The STI rear diff and wolf creek half shafts sort of gives me a newer diff, with an LSD, and a higher gear ratio for a pretty decent price. Rebuilt Z diffs seem to go for about 900 bucks. I figured this is a viable alternative. I would NEVER put a V8 into my car. I love my datsun spirit L28. The STI rear diff is a 3.90, so it is not a huge step from my OEM diff. Plus if I ever get a 5 speed in there, it will work beautifully.

It must be an STI rear diff, which is the R180 just like ours, the WRX diff is the R160, and it will not work in 240Z's. My bid for an STI diff fell through... back on the hunt. Huzzah! 499 shipped to my door! 2004 STI rear diff, 3.90 ratio, LSD, with 45000 miles on it. Next up is wolf creek racing out put shafts.

Exactly, I am not really sure I need a LSD, but the going rate for STI LSD's is about 450-550 bucks Throw in the WCR out put shafts and you are looking at 900 dollars for a pretty bulletproof rear end.

I have replaced everything in the drivetrain except the Diff in my Z. I am going to do this in stages. First I am going to buy an R180 STI LSD differential. Already bidding on one on Ebay. Next up is the Wolf Creek output shafts so I can bolt up my half half shafts Finally after I save up a few more dollars, I will get the CV shafts form Wolf Creek to complete the conversion. I plan to take as many photos as possible. I may drop the rear suspension to replace the spring top hats. But we will see how bad the 'while I am at its get'

I would like to try this one day, but the question is, how long will it last before the repaired portion becomes annoyingly visible.

welcome and good motoring.. These cars are addictive and never get boring. They are also a joy to work on.

I agree with Carl B. But it does come down to your usage and your future plans. I wanted to keep my 71 all original for a long time, before the mod bug got me. Then I changed and made it a bit of a Datsun 'best of' car. I would never drop a SBC into one, but at the end of the day you only have to answer to yourself. The rules are simple and never change. All original cars are worth more. All original cars in great shape are worth even more. The only original once phrase is overused today. I see non running rust heaps dragged not rolled out of a barn being sold for more than a fully restored car.

are these NLA from motorsports auto? I bought one about 3 years ago

Dear God, I may buy one just to have it

Great work John and Greg! I just want to echo the words of Mr. Beck. To come into a one off race with a just finished car and finish 10th is stellar and speaks volumes to the quality of driver Mr. Morton is. HUZZAH!!!

God Speed my friend, I had my eyes on it, but life and kids and family just did not line up.

i have been thinking of changing my interior on my 901 silver to red. Ever since I saw that silver/red Singer 911 I have been forever dreaming of that combo.

HUZZAH! Good for you man! Way to work through an issue!

I am going to print this an save it the next time somebody tells me tuning triples is in ANY way difficult. good luck my fellow engineers and tinkerers extrodiare!
