  1. I finally have my meeting with the engineer to see if he is happy to sign off on all of my modifications. Fingers crossed.
  2. Now the car is running I just have a few bits and pieces to sort out before I can get it registered.
  3. 175kph. That dyno is strange though working in HP and ft/lbs as most here in Aus use KW and NM.
  4. Are you talking about the road speed reading? The Dyno was all working well.
  5. The engine was in the car, not on a stand so that should give you a hint 😉
  6. Yep. I didn't talk about the tuner as he doesn't want to be flooded with calls and more work as he has plenty to keep him going forever 😉, but he is basically THE Datsun guy in Aus' and has been building Datsun rally cars forever. As for the washers, I got the engine as a bare block so I didn't know about them and when I fitted the manifold, I didn't really think about it too much. What we actually ( or they to be specific) did, was pulled off the manifold and put it on a mill to match the thickness of the inlet manifold to the exhaust manifold and then they all bolted down nicely.
  7. I finally sort out the running issues and no surprises it was my fault. We then tune it up on the dyno and get that final figure.
  8. That is a handy diagram. One of my viewers pointed out that the way I have it, any overflow in the tank will go straight into the carbon canister. The easy fix is to just turn the T piece at the fuel filler neck, so that the breather line is facing up not down. Hopefully that will avoid any issues.
  9. In this episode I delve a bit deeper into the tuning issues on the 680G.
  10. Many of you have been asking me what is happening and I finally have an update for you, and some info on where I am planning to go in the future.
  11. It is finally time to do something a bit more permanent about my spray booth.
  12. After 18 long months of tinkering in the garage, I finally get to drive the 680G.
  13. Thanks Mike. I will have to play around with mine, but like you, I have now got it going. It is not as intended by 123, but while it is working I am ok with it. It is something I can play around more with later, but overall I love that it is flexible and programmable. That makes all the difference to me.
  14. Yes. You can program in the advance at whatever RPM intervals and advance you would like, which is a great idea in my book. As for the shaft drive, I could set the drive up 90 degrees out, so that the rotor sits in the correct position, but it is working for now, so I am not sure if I can be bothered pulling it all apart again right now.
