  1. What do you mean by stub axle? The part that goes in the side of the differential or the part that goes in the bottom of the strut and connects the half shaft to the wheel flange?
  2. There is your clue. The oil pressure sending unit is just a variable resister. If I recall correctly, the sending unit basically grounds the oil pressure gauge (moving the needle) as oil pressure increases. So, if when the wire to the oil pressure gauge is connected, and the gauge needle goes all the way to full pressure, what does that imply: The wire going to the sending unit is shorted out? However, when you removed the wire from the sending unit, the needle did not move. So you can rule this out. Or the sending unit is bad. Another test: while watching the oil gauge, with power on, short the sending wire to ground. What happens? Does the needle move to full pressure? If the needle moves the gauge is ok.
  3. By cones do you mean the rubber residual check valves or the cone shaped seats the brake pipe seats sits on when mated to the mc? And yes every 280zx mc I took apart had the rubber residual check valves.
  4. Re: Holley model number 4150 Street Avenger 570 cfm p/n 0-80570 Goodwrench SBC 350 crate engine Gathering parts for rebuild due to ragged idle on start up and low speed surging up to 30 mph. High speed cruise and WOT car is still a rocket. Car dyno tuned in 2010. Ran fine for 10 years until about a month ago. I am researching the replacement part number for the primary metering block should I need one . The Holley website does not give a p/n for a metering block for the 570cfm carburetor. I found a Holley part number cross reference pdf that lists the metering block for the 570 cfm carburetor as n/s (non serviced). So if the metering block needs replacing is there another Holley p/n that will work?
  5. What year and model z car do you have? Will it be a daily driver? Any mods done to car?
  6. There are three install kits available: Jags That Run (JTR) Motor Sport Auto (MSA) Johns Cars Each has its own pros and cons. Driveshaft alignment is critical for all of these kits. You can research each one at HybridZ and Google search All of the kits assume that you have some automotive mechanical skills. If not done correctly these cars can kill you,
  7. Useful information Download a Factory Service Manual (FSM). http://forums.hybridz.org/topic/48825-factory-manuals-some/?page=2&tab=comments#comment-1208329 Buy the JTR Datsun Z V8 Conversion Manual from http://www.jagsthatrun.com/index.html Read it at least five times. Download electrical schematics for your car. PDFs are easier to read than those found in books. Some are in color. Buy the book How to Restore Your Datsun Z Car by Wick Humble. It will save you hours of searching for "how to" info. Focus on searching Hybridz as 99% of questions have already been addressed. Start bookmarking Z car parts suppliers - there are many! Remember these are 40 year old cars and will need restoration to be safe and drivable. Join ClassicZCars.com website and search there as well.

  9. Try starting the car with the wire to the oil pressure sensor disconnected from the sensor and observe the oil pressure gauge. With the engine running and the wire removed from the sensor what does oil pressure gauge do?
  10. If you can block the engine up, pull the transmission (leaving the bell housing on the engine) and loosen all of the clamps that hold the fuel line in the tunnel you may be able to move the fuel enough to cut that group of fittings off. Then you can install a A-N hose fitting to hard line adapter on the fuel line. You will have to teach yourself how to make up a SS braided hose ends (fittings). The other problem you have is that the transmission is actually riding against the fuel line. The PO cut a piece of the transmission out to clear the fuel line. You will need to address this by re-routing the fuel line away from the transmission.
  11. I don't want to scare you, but that first 240Z V8 project I mentioned above was so FUBARed up by the previous owner that we ended up pulling it completely apart (shell) and started over. The only part we kept was the engine.
  12. You can also use Microsoft Paint. Open the picture in Paint and select Resize. A picture can be resized between 1% to100% up or down.
  13. I didn't see this before I had coffee. It could kill you. So re-engineer your fuel line routing before driving this car. Suggest that you post pictures of the fuel tank to fuel pump to fuel line and include showing how the fuel pump is wired. In other words all of the fuel related equipment, wires, pump etc back by the fuel tank. I now suspect there may be problems in how the fuel system was built from the tank forward.
  14. By the way, did the previous owner install an oil pressure sensing fuel pump cut off switch. In case of a crash you want the electric fuel pump to stop pumping gas. The oil pressure safety switch senses when oil pressure goes to zero and shuts off the fuel pump. Basically, power for the fuel pump runs through the switch to a fuel pump relay (recommended) to the fuel pump. When the engine is running oil pressure rises and closes the switch energizing a relay that closes and switches 12 volts to the fuel pump. Without the relay, the oil pressure safety switch has to carry the amperage load demanded by the fuel pump which sometimes burns out he switch. Also, the fuel pump is most efficient when it receives a full 12 volts. Painless sells a very nice fuel pump relay harness that can be connected and triggered by the oil pressure safety switch. See picture below. There are alternate install locations and methods to cut off the fuel pump. Recommend that you purchase the Jags that Run Datsun Z V8 Conversion Manual and memorize it. The manual explains how to build a safe V8 Z car.
