  1. Updates! 1) Got the vintage air unit mounted under the dash and AC lines plumbed to a bulkhead fitting in the firewall. 2) Plumbed heater hoses to the vintage air unit as well 3) Got fuel lines completely finished up and mounted up. Including regulator and tank vents. 4) Started plumbing vacuum lines, about 75% done In the next couple of weekends I'll probably be finishing up the vacuum lines. Then mounting the radiator, fan, and coolant plumbing. I also had some time with one of the 3d printers at work, so I modeled up a velocity stack and printed it for some practice. The surface of the print has not been cleaned up at all, hence the left overs from the supports and rough finish.
  2. Progress has been slow due to the following factors : Finals Finding a new apartment Work travel Graduating from college this week Starting a new job on Monday But I had some time this afternoon so I made a mount for the coil packs and got that done. There has also been progress on wiring. chassis re-wiring is done. Need to finish up gauges and tie it all in with the engine harness. Slow and steady.

    current sensing tachometer

    Brian at technoversions got back to me. I just placed an order for his adapter, and it'll be a couple weeks before I have time to actually wire it up and test it. But this is the general diagram I'm going with. I'll bump this thread with updates later.

    current sensing tachometer

    While posting this I also emailed technoversions with my questions. He's currently looking into the MS manual about the tach signal output, but he believes that the tachoutput signal from MS should be enough to trigger his adapter. If that is the case, it can be wired up similarly to his diagrams. I'll report back once he gets back to me. I'll make sure to document all of this after I get it working in-case someone has similar questions in the future.

    current sensing tachometer

    So I've been doing some reading on this, and I want to make sure I got my ducks in a row before I spend money on an adapter. Car is a 1973 240z, being converted to MS3x 3.57. Factory wiring is gone, no coil etc. Here is a pic of my tach, which if I understand correctly is the current sensing type. I've been reading this thread about using a MSD 8920 adaptor. And here is the manual provided by MSD So from my understanding there are 4 wires on the MSD box. 1) Ground 2) Tach signal input 3) output to tach 4) violet (unused) I connect the MS tach signal to wire #2. I take wire #3 and connect it to one end of the tach loop. I connect the other end of the tach loop to a +12v power when the car is running or starting. And I ground wire #1. Will this work? The other option is using a TM-02-I from technoversions. The instruction manual can be found here. 1) One end of tach "loop" connected to +12V when running or starting 2) Other end of tach loop connected to pin 3 on the tach adaptor (with or without power resistor?) 3) Pin 1 connected to +12V when running or starting 4) Pin 2 connected to ground 5) Pin 5 connected to megasquirt tach output? Also, on the technoversions adaptor manual, what is the difference between the two +12v sources?
  6. I've been traveling for work the past few weeks so I haven't been able to get much done. But this weekend has been pretty productive. Got the distributor swapped over to the turbo distributor to give me crank angle and cam position. Got the AC compressor mounted as well. I had to CAD up and mill out a little bracket to adapt the throttle linkage to the factory triumph cable pull. Here is the completed linkage and a crappy vertical video
  7. While I've been doing all this work on the car, I've been in contact with Softopz, and he's been making me a megasquirt harness for my needs. He recently sent me work in progress pics, and has been great to deal with. I'd highly recommend him if you are interested in going the megasquirt route. Here is a link to his thread where he sells harnesses.
  8. Thanks for the info guys. I appreciate it. This weekend is pretty busy for me so I didn't have much time to work on the car. In the meantime, I finalized the header and intake install and they are on for good. I had to wait for a new gasket that arrived a couple days ago. I also got the thermostat housing on, and the fuel rail and injectors. The throttle bodies are still only on there temporarily.

    240z L28et Overheating

    It looks like it clears an AC pulley, but it seems like it might interfere with the belt / compressor. Hard to tell from the pics.
  10. I got a couple questions for you guys. 1) Since I'm going to be running LS coils, what kind of spark plugs should I run and at what gap? 2) Since I rebuild the head and it has a brand new cam, what break-in procedure do you guys recommend? And what oil should I run during break-in?

    Thanks a lot, those pics are very helpful!
  12. Did you also run a vacuum reservoir? Or are you just running the pump to the booster?

    240z L28et Overheating

    It would be great if you can get a pic of the waterpump pulley as well as the AC pulleys. Also if you can, would you be able to measure the thickness of your radiator? I have a similar setup, but slightly different radiator and am curious to see if I could fit the altima fans. Thanks.
  14. Started test fitting stuff to check clearances. Also got the fuel pump installed in the tank this weekend. Next weekend is probably going to be running fuel lines, while still procrastinating the mess that is wiring. I also need to get another set of triumph velocity stacks, because the two sets I have are currently mismatched...

    How did you wire up the altima fans exactly? I recall they are a 4 wire plug due to high / low speed settings right? Are you just running high all the time? And how tight is the fan against the motor? How's the clearance for the pulleys and belts?
