  1. Think I might have misunderstood what you initially meant. Good point, no I'm not sure how many bearings they have.
  2. I ordered a print in nylon, no hubs here in Norway but there where a couple in Sweden and Denmark, so I'm gonna have to wait a little bit longer on shipping but I'm on vacation anyway so... Like I said earlier the guy I spoke to locally could order some plastic with a 120c melting point but I think that might be to close for comfort in this application. For intake ducting or something like that I'm sure it's OK
  3. Here's an interesting story about the use of plastics in engine applications: http://www.assemblymag.com/articles/86440-plastics-under-the-hood Seems Nylon might be the way to go for something like this. I got quoted this from 3dhubs: So yeah, expensive. I paid something of the equivalent of 120usd locally to have some bolt spacers for the 12mm diff center made up, so factor in the material needed for something like this and I guess it's just as expensive if not more here. The family hauler is 2015 Peugeot 308 station wagon and it sure does have alot of plastic underneat the hood, and I also have a Z32 and if plastic can survive the scorching heat underneath that engine bay i'm sure it can survive the relatively drafty datsun engine bay but I need to find out the right material to use, I think that's the most vital clue. Exiting stuff this, I've already started thinking about other uses for 3d printing like cold air intake ducts, intercooler ducting and stuff like that Overall it is a pretty simple shape. I don't know how the machine shops in Norway would work, but you could take some pieces to a machine shop or engine shop here and they could build it for you for a fairly reasonable cost if you supplied the right diameter material.
  4. First I would go to the ego controller and choose "disable" to make sure it's not veal or closed loop thats affecting your idle afr's. Even with it disabled tunerstudio will read af but autotune or any other form of closed loop will not interfere with anything. As far as dead time goes I can't help you but I just used the default tunerstudio 0.9ms on my Z20E (low ohm injectors with resistor pack) and had zero issues.
  5. Smart, are we talking iron particles or how big wold the iron added be? My main concern also is heat, hopefully there will still be some sunny days left when I get back from vacation so I can get some more temperature readings. I see 3dhubs.com is also offering cnc services now so just for the heck of it I've sent a price quote for this part in 6061 aluminium. Less costly alternatives are ABS, Nylon and polycarbonate.
  6. The oil pump shaft doesn't even reach up to the spacer, from the face of the flange down to the shaft the distance is 65mm, if you look at this picture( https://photos.app.goo.gl/EbhlMDl34KjKTMJX2) you can see the end of the cas axle where it slots in to the oil pump shaft just like the standard distributor does. And the cas axle is supported internally like the distributor is too. I don't understand why you would want a bearing in the spacer?
  7. Thanks, I found this article which also explained it and had a few other tips as well http://support.3dverkstan.se/article/38-designing-for-3d-printing Of course billet would be pimp as f... but in the end i have to consider the cost of this and having something printed may be cheaper and just as good for the work intended. With sintered plastics, fiber reinforced and you could even have it printed in metal (but that's probably insanely expensive )
  8. What are filets? I'm not experienced with 3d printing or even designing stuff like this, this is the first one I did. I found a guy in my hometown through 3dhubs.com who printed it for me, this one I think melts at like 100 degrees Celsius, which isn't a lot considering the temperatures I measured on the timing cover and flange and distributor where in the 65-75 range with the engine idling at about 17 degrees ambient temperature. I'm thinking if you suddenly get some hot sunny weather like today with temps at 25-30 it's gonna get real hot under the hood. He could order some plastic that had a melting point of 120 degrees c but I'm still not sure if that's enough what do you think?
  9. I have a Z20E engine in my 720 pickup that's been turbocharged and ecu has been swapped to a megasquirt based ecu. It's running fuel only for now but for ignition I'm gonna be running coil on plug triggered by a SR20 CAS with a diyautotune triggerwheel. Inspired by the Japanese running the rb efi stuff on the l6 engines I designed a similar pedestal to swap the distributor for a cas and had a guy 3d print a prototype so when I'm back from vacation I'm gonna swap it into my running engine and try it out.

    Just don't hold your breath waiting for new episodes though. But great show
  11. datsun 240z with porsche 911 flares :)

    With that blue color and that rb engine I wonder if this isn't the same Z I saw for sale here earlier this year. Was really nice but the ad is gone now and the only one for sale is an m3 powered 240
  12. Hey guys, I have a datsun 720 I'm working on and have a c200 lsd rear axle but it's from a diesel so it's geared really low. So I just wonder if it's even worth trying to sell? I wanna replace it with a 3.5 or a 3.7. C200 internals interchange with R200 shortnose internals but 4.87 is really low so would anyone want it?
  13. I'm looking for a crownwheel and pinion in either of the afforementioned ratios. Will pay for shipping. secure payment via paypal

    I've used them on a couple of builds. Quality stuff. On the Z I think I ordered the 3 3/8 size for tach and speedo.
  15. I sold my Z, so I could buy a ZX twinturbo. It's nice to have 4 seats when you have kids, plus the performance of it is much better. But if I had had enough space I would have kept the Z too
