  1. Since there is a crank breather and rocker cover breather do I: A- Buy two catch cans and plumb one into each of them and then to the turbo intake B-Buy one catch can with two inlets and one outlet or C-Buy a regular catch tank and connect it to the crank breather and let the rocker cover breather vent to atm or put a breather filter on it. D-Same as C but "T" the crank and rocker breather together before the catch tank. I feel A and B does the same thing, and cost wise is about the same as well. Astetic reasons would put B over A, less clutter in the engine ba
  2. I've seen a s30 on YouTube with a Mercedes om606 turbodiesel. Think it was built in Finland
  3. You ARE using the L28ET ecu are you? If you'r still running the l20e ecu then it will run really rich if you swap to bigger injectors. Been there done that...
  4. There's tons of info on this topic around the web, but in short: most engines develop the best performance slightly richer than stoic, na's around 12-13:1 and turbos around 12, maybe 11, some even richer as a safety measure. Idling, most batch fire engines like a slightly rich idle, sequential injection engines can often idle closer to stoic but the important thing is to get a smooth idle, not to chase numbers. Cruising can see leaner afrs 15-16 maybe higher as long as it runs smoothly
  5. Sounds a lot like some dodgy wiring or earthing somewhere. I had a bluebird 910 with the z20e engine that would just stop sometimes, and then all of a sudden it would start and run fine. Was as simple as a loose connection. Your ecu gets it's trigger signal from the coil negative, it's a batch fire setup so it fires all injectors once every revolution, it also needs a crank signal, this comes from the ignition switch or the wire going to the starter from the ign switch. You need to check that you have continuity between coil negative and the tach input on the ecu, al
  6. Think I might have misunderstood what you initially meant. Good point, no I'm not sure how many bearings they have.
  7. 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
  8. 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
  9. 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.
  10. 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.
  11. 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?
  12. 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 )
