  1. Haven't seen this posted but worth a look.
  2. These moldings are still available from CustomAutoTrim.com But they are expensive.
  3. I have a Saturn electric power steering unit and the electronic interface available for anyone who would like to do this conversion. I was going to use this on a Miata engine swap, but decided to engineer a new engine bracket and retain the hydraulic PS system. PM if interested.
  4. Silver is a non-color, and the original Datsun blue/green being darker is almost a negative color. Some of the prettiest engines I've seen on this forum are lipstick red accented with the natural aluminum color on the raised letters and ribs on the valve cover.
  5. The oil pressure sensors available today are designed to work with gauges and/or idiot lights. When the oil pressure is above 8 psi or so, the sensor connects a potentiometer and reads a resistance. This resistor is in series with the meter in the gauge. As the resistor varies, the meter varies. When pressure is below 8 psi, the sensor disconnects the potentiometer leaving an open circuit. For idiot lights this forces all the electric current to flow through the bulb, lighting it. For gauges an open circuit causes zero current flow and the spring in the meter forces the needle to the left extreme position, just as it does when the ignition is turned off. The oil in our early Z engines gets thin when the engine is hot as when driving at highway speeds. Idling after pulling up to a stop sign after a highway speed drive will often have oil pressure below the 8 psi limit. The pressure will increase once the revs go above idle. I was told by an old timer not to worry about it. Its a gauging problem, not an engine problem.
  6. Not a final answer, but interesting: http://www.moonzstuff.com/articles/oldhandwriting.html My vote is for "Lieut". Name spellings and abbreviations were far less standardized back then.
  7. BTW the link you posted tried to hijack my browser. Don't click on the link.
  8. There is a minimum warm coolant temperature you should strive for - 185 degrees F. Due to radiational cooling overnight, water vapor can condense in the interior walls of the engine. And despite common knowledge, oil and water can mix to a slight degree. Oil can absorb up 1% water by volume. This water can drastically reduce oil lubricating ability and must be removed. Raising the temperature to 185 degrees is high enough to drive off the water.
  9. I use Grundy after Hagerty said I drove the car too much. Been happy with Grundy and also use them to cover my daily drivers at a very competitive rate. I saw an TV ad recently where Hagerty says they no longer restrict mileage. This maybe why your rates jumped so much this renewal. One difference with Grundy is that they write stated value policies for many cars when they identify them as future collectibles. My wife bought a 2 year old Camaro Convertible a couple of years ago. They came up with a stated value higher than what she paid for it. When it got totaled 6 weeks later (not at fault), Grundy ( through AIG) sent us a check no questions asked. Said they would go after the at fault driver's insurance.
  10. Fitting for as simple a vehicle as a Miata, the CAN BUS is a fairly simple single high speed bus. Since my transplant vehicle does not have Dynamic Stability Control or Advanced Key Locks, The only control modules are: the Engine Control, Transmission Control, Instrument Cluster, ABS Brake Control and Hard Top Control. The Instrument Cluster receives Vehicle Speed, RPM, Engine Coolant Temp, Odometer, Fuel Injection Amount from the ECU. It Receives Transmssion Gear Selection info from the TCU. It also receives indicator status for MIL, Generator Warning, Cruise Control Status, Brake System Warning, ABS Warning, Power Retractable Hard Top Warning, AT Malfunction Warning, It outputs Fuel Level to the ECU. It exchanges Immobilizer signals with the ECU.
  11. The only physical connections required are a CAN BUS High, CAN BUS Low, CAN BUS Ground. The voltages on the CAN BUS are all standardized.
  12. For those familiar with the J1979 standard. I am transplanting a 2012 Chevy LFX engine into a 2011 Miata. (could find a reasonable Z transplant candidate). Since I have a post 2008 CAN BUS devices, I am wondering if I could connect the ECU CAN BUS signals into the Mazda CAN BUS to drive the instrument cluster? From what I know about CAN BUS the basic performance parameters are polled using a standard prefix and a standard bus protocol. Other manufacturer specific data points would not be polled, but they shouldn't be needed to run the instrument cluster gauges. There would be several advantages in using the Mazda Cluster rather than replacing it with Speed Hut CAN BUS gauges. Besides limited space available in the Miata, there are some 12 indicator lights for non engine functions that would have to be replaced with the Speed Hut Gauge package. The Camaro gauges can't be used because the Body Control Module converts the high speed bus from the ECU into a medium speed bus that feeds the Instrument Clusters. The Miata however, drives the instrument cluster directly from the CAN BUS. How feasible is this?
  13. It looks like some bezel rings are in your future. Good job otherwise. I found an unusual source for 2 1/16" bezel rings. Holley Carbs now sells instruments for their EFI setups and includes a variety of black and Chrome rings. My hub ring option is cheaper though.
  14. I've gotten the Z up on a lift to check mounting options for the LFX/6L50 combo. Doing this to help others who might want to go this route as well as keeping my options open. The tranny mount points look strong and would be a good starting point to lay out an installation. Because the LFX is shorter and has a different mount position than the L24, using the tranny mount points would put the LFX engine mounts about 5 3/4 inches aft of the center on the Datsun engine mount towers. This suggests using a cradle mounted across the front rails. It would require removing the Datsun towers to provide clearance for the alternator and AC compressor, but otherwise everything else fits quite nicely. Does anyone see a problem mounting the cradle across the top of the rails rather than underneath like the front cross member? Would you need to re-enforce the rails because you are now loading and extra 150 lbs per side? Comments welcome.
  15. I've been frustrated looking for a candidate Z to receive my LFX/6L50 with the added technical problem of devising an engine mount. Just about any local candidate is extremely rough and/or missing tons of serviceable interior components. This doesn't even mention the price being asked for rolling shells. Considering what hybrid Z's are going for these days, it's getting hard to make any economic sense. While looking for mounts I've found a company that makes one to fit the LFX into the Miata who might be willing to design/fabricate one for the Z. Frustrated in finding a serviceable Z, I've begun looking at a Miata candidate. Being readily available, I find they are also have similar weight and wheel track to the Z. Also they offer antilock brakes, air bags, etc. So before taking to the dark side, I'm putting out the call for anyone with a serviceable Z that they would like to see living a happier, longer life. Obviously, price would be dependent on completeness and condition. I'm not a sheet metal worker. Engine and transmission condition is obviously not important as they will be replaced . Please PM with candidates, otherwise your comments on the Miata would be welcome in this thread.
