Fearedi Z31

Over at z31performance.com a lot of talk of the 71c tranny swapping capabilities has been debated. Same thing goes here. The bell housing is different for our Zs, but the gear cluster is the same. If you wanted, you could pick up a N/A 300zx(84-89) 71c tranny and just swap the bell housing to what you want. There you go. Another option for ya. :thumbup:

Well in either case, older cars are having a tough time getting the oil they need. A lot of talk of this I've seen with older muscle car people. A lot of them are either buying diesel/heavy duty oil, or buying ZDDP in a can. I've not tried the can stuff before. The problem running diesel oil though is it attacks your cat. So if you live where I do, you won't care what happens to the cat. If you live in Cali, ya don't do it. Yes and no. A lot of it depends on your millage and age. My car ran fine with it, but I switched because its so damn expensive. $50 plus per oil change is outrages. I'm also hearing that synthetic oil attacks your seals. It will make them "shrink" and cause oil leaks. Never seen proof of this though. Another factor is also a Big issue. What we think is normal driving: (going to and from the store, going to work, picking up the kids, etc) is severe driving. Driving dusty roads and climate are also factors. So choosing the oil You think that best suites your driving style would be something to think about. Hwy driving is what I believe to be the best conditions.

The problem with newer oils is the lack of phosphorus and zinc content. Another element is also important, but I can't remember the word. Zinc is a very important thing for older engines. Zinc is needing in all motors actually because it is a crucial lubricant need when 2 pieces of metal rub together. I drive a 89 300z, but still need the higher content because of my flat tappet cams. Diesel oil or actually Heavy duty oil still has high amounts of both elements. 1000ppm of both elements is still in most heavy duty oils. Sadly though, the feds are trying to cut down on these oils as well. Most average oil now a days, barley have 400ppm. Valvoline VR1 is a good choice if you don't want to try heavy duty oil. 800ppm of both elements is present.<Don't quote me on that though. I am currently using 15w-40 Mobil Delcac. It runs really nice but hard start ups in the cold. Gona try the T5 10w-30 Rotella for my next oil change. My millage is currently 130k.

Where ever it's gona be, I'm down to show some support.

Hurry up and fix the clutch, I'm itching to race ya. I hope you get everything squared out soon enough.
