6 month update after adding an EFI/Turbo/EDIS/L28ET/5speed to a 240Z: -The MSII 3.57 from DIY Autotune has worked flawlessly. -The EDIS ignition has been flawless (after buying the new coil pack and module). -The EFI injectors, resistor pack, home made fuel rail, '75 gas tank and Walbro pump are st...

Thanks! But I do consider it the end of installing that "free" turbo engine. Now that all the systems (intake, exhaust, ignition, fuel, cooling, electrical, transmission, dash gauges) have been adapted, I'm freed up to just do maintenance. Maintaining is 100 times easier than creating! Rig...

End of project Installed radiator and temps are now correct. The Alternator swap already eliminated the flaky voltage spikes. The car is finally DONE. :yeah!: It took about 6 months total time and roughly $4,400 to complete the engine and have it installed correctly. That was twice as much time and...

. electrical load The electrical load is a bit too much for the ancient 240Z alternator and old external voltage regulator. I'm getting swings in the voltage that are resetting the WB 02 sensor and (seemingly) causing irregular injector responses. I've added the following fuse rated circuits to the ...

More Conversion "gotchas" . Every picture I remember seeing of turbo conversions must have been in the early stages of the build since none have any heat shields installed between the intake manifold and the exhaust manifold. I patterned mine after that "clean look" too but I no...

Ok, the WB O2 was tested on the bench with an (unlit) propane torch aimed at it and it began to register in the 10-12 range. Re-installed the now known good WB (but now at 18" down pipe from the turbo ) and started working on the fuel control by reading the LC1 AFR gauge (now loosely mounted in...

The "runs fine" was a bit premature. An overly lean mixture is being seen on the spark plugs(white electrode) and water temp is 20-30 degrees hotter than normal now that I took the car on the road a few times. The heated NB O2 was reading hard-over lean so I replaced it with an DIY Autotun...

First update after initial start and run proved successful: I found out that the common saying I've heard posted everywhere that "EDIS module can operate the engine by itself in a limp-home mode" was a huge exaggeration about it's reliability. Fact is that there are 3 points of failure on ...

Background: I own a 240Z and one day a friend basically gave me a very used 1983 L28ET engine core. Everyone said that the turbo swap was easy (that it was just a drop in replacement) and use Megasquirt (since it's easy to configure) and use EDIS (since it's easy to control and reliable). It seemed...
