I finished the adapters for the IAC and TPS today and got them mounted to the manifold. Vinyl cutter came in handy when cutting some gaskets for the sensors and throttle body. Mounted the throttle body adapter and throttle body to the manifold as well.
I also finished up some wiring on the megasquirt for the idle stepper valve control. Works great! Cant say that for the m50 TPS tho. The one I got turned out to be a dud after hooking it up to megasquirt and attempting the calibrate it. I opened the sensor up to find a broken wiper arm. Ggrrr! Time to search for a new one now.

Yesterday I removed all the CIS and K-jet turbo parts from the engine bay in prep for the EFI turo install.
Along with that I also removed the complete wiring harness. I will need to tear it apart and get rid of everything I wont need and integrate everything I will need into the MS harness.

Keep it up man.
Excited one day I may actually see it running in person

Well, the 318i coolant neck has been drilled and tapped for the MS temp sensor along with getting cleaned and painted. The BOV also got a sprits of fresh paint (not the greatest, but no one will see it anyways, lol).
I also removed the Megajolt unit (which is for sale by the way)
And I went ahead and tore apart the oem wiring harness. This was definitely an interesting thing to do. So much wiring was removed it shocked me.
What was removed
What needs to stay

Looks like a ball of yarn in that first wiring pic. Should help to keep the bay clean!

Did some more work today on the beem. I ended up cutting the grooves in the injectors for the clips to hold them to the rail.
Fitted them in the head and found out the hard way that the FPR hit the head, not allowing the fuel rail to sit correctly. So, off came the FPR from the stock e30 318i fuel rail. I will be welding the hole shut on the rail and redrilling it on top of the rail in the same location as it was. Then, welding an injector boss (since the FPR has the same diameter o-ring as the injector) and the FPR mount in the new spot.
After cutting the FPR mount off I fitted it to the head with the injectors and seems like it will be perfect. Until I put the intake manifold back on.
The hose nipple that I was using for the feed to IAC interferes with the fuel rail, so off it came too. I jb welded it closed and will just need to smoothen it out inside the tb which isnt a big deal.
So things are back on track once I get that fuel rail and FPR stuff welded and clean up throttle body. She's getting there!

I thrive to be different and do things in a "think outside the box" manner. Plus, I like the intake manifold I have vs the ugly stock e30 318i one.

I love when I see a notification for this thread being updated.
When this is done, you will be the resident m10 turbo efi expert.

As it should .... 8v > 12v > 24v .... do the math!!!

So you are sliding into the tent tonight and firing this up?!

I think once he gets a TPS, and gets the fuel rail welded up, its just a matter of making a fuel rail mount bracket, modding some of the charge piping, and wiring up the sensors.
I THINK HE TOLD ME HE WOULD HAVE IT DONE NEXT WEEKEND
Im pretty sure it bugs the crap out of him when I prod him like this , lol.

You both are bastards!!!

Well more progress this weekend. Drilled a new hole in the top of the fuel rail and welded up the FPR mount and old hole. Turned out rather nice.
Mounted it all back on the engine and it fits very purdy.
Started figuring out the mounting location for the fuel rail and decided to bend up a bracket to go from the stock fuel rail mounts to the manifold stud.
Then I also started running the megasquirt harness and wiring through the firewall and into the engine bay. Boy this is going to be some tedious wiring work!!
