1976 280Z Restoration Project

 Build is looking good. Too late now but I would have mentioned that you could shove 14mm high impedance injectors in the stock manifold and they will seal. Probably a mute point if have a 11mm fuel rail. I’m running Audi 1.8 Bosch type now.

As far as catch can , PCV, etc, I added a pic of mine . You said you run a catch can, probably plumbed the same way. There’s a few hoses there if you can pick it out. The hose off the intake is for the IAC . The can catches more than I thought. 

I like how you cleaned the intake up. I need to do a cable myself to get rid of the linkage. 

 

[wheee!]

TPS sensor plate came in today too!

I was ready to go that route when I thought I was having issues with my TPS . Looks like a cool set up

The Haltech is so configurable and definable for inputs that it leaves me with these great opportunities to tune and refine the entire combustion process! I am really excited to get all the sensors installed and reporting to the ECU in order to max out the potential of this motor.

Good news is, a certain influential someone who sold me this motor just got HIS Haltech system working with a similar setup, so that is very encouraging!!

Haltech should be great. What MAP sensor are you going to run and where are you installing it?

Is that on the 510?

It has been fun for me to play with all the numbers . With complete control you can run a ton of advance and run the motor lean without worrying . Cruise at 16AFR and 45 degrees all day . The beauty of having a well engineered mechanical platform and modern technology to run it

The Haltech Elite750 has a built in sensor for MAP that runs off a vacuum line from the manifold direct to the ECU

*bingo!

I also added a fuel pressure monitoring circuit to the return fuel line on the recommendation of my Z Car Club. The Haltech can monitor the pressure and shut down the timing if the fuel pressure drops below a preset. Cool! This along with two liquid pressure gauges in the engine bay should keep me well informed.

Fancy!

Beware condensation in the MAP sensor line will roll down hill right into the ecu and kill the sensor . I had to go external . Unless you can use a newer style that uses no hose to the ecu

I will route my vacuum hose in a manner to avoid that. Thanks!

Pretty sure you will need an additional sensor for sequential . That one wheel can’t do it all . Maybe you misunderstood them. Still- I’m only running wasted spark and it’s still light years ahead of a dizzy
