Just got done reading the whole thread... Simply a work of art. Congratulations! How are you gonna do timing? I did not read or missed that part if discussed.

I bet you spent the whole rest of the day just cranking it around and listening to it go "woosh, woosh, woosh..."

Wow, thanks everyone
Direct injection no, variable intake maybe but probably also no, the intake manifold I made is a bit on the longer side, so power will taper off a bit at really high rpm's, which isn't such a bad thing for reliability, so I might leave it like this even though more horsepower can be made with a shorter intake or a variable one.
I'm using a 4-channel ecu which get's a signal through a CAS which is looking at a 36-1 triggerwheel. The ecu will drive 8 coil-on-plugs, so each channel drives 2 plugs, so no split-timing.
Yeah haha! I assembled the engine last friday night, and by the time I was done it was like 2:30 o clock at night, so I was much too tired to type a story to go with the pics, so I just threw some pictures on here and went to sleep
Will do
No I'm not, just the peripheral ports. All the side-ports are filled with defcon, but not the entire intake runner in the iron is filled, just the last inch, so I blocked the outside of the ports by tig-welding a blocking plate in there. This was needed for the center and outer irons, they are FD irons that have ports that sit higher. The intermediate irons did not need blocking plates, their ports sit lower so it will be covered by the slide-throttlebody housing, You'll see.
You got me , it does make lovely whoosh sounds, but since it's a 4-rotor it's almost like a constant whooooooooooosh noise , Must try to avoid doing it though, or this engine will need a rebuild before it's even in the car
hahahaha

Just seen the updates.. Great work John.. You must be very please.. I am sure there are a few hurdles to get over still but looking very good so far. But I think you have crossed the worst!
Cannot wait until you get it running!

Congrats John. Great work. It would be nice to see you or someone with skills at your level tackle a new more robust coolant seal design for these engines. If someone could come up with a foolproof design it would be one more failure point eliminated.
Again, excellent job!!! Cant' wait to hear it RUN!

The only issue I see is how you reliably join the two copper end pieces.
Any feedback is appreciated.

I was actually thinking about that my self, if somebody wants to look into a "Bare Soft Drawn Copper Solid Single Wire" with the right diameter with some crush capability. Now that would be the last of coolant leaks on track days.

Yeah, me too! Sadly nothing has been done to the engine this week though, I messed up the pilot bearing seal and decided in a clear moment that I really should not re-use an oil pump chain in a 4-rotor engine, so I ordered those, but since part availability sucks here it's going to take over a week for them to get here. So in the meanwhile I've been doing a little chassis work, mounted the roof, rear bumper, assembled and mounted the headlights, currently respraying the rear window which looked ok without a respray at first but not so ok when mounted onto fresh bodywork. Also worked on my e30 beemer mule, it failed it's tech inspection horribly because the inspector thought it was a death trap. He was very right of course. So pretty boring stuff at the moment, I'll try to get a few pictures up next week.
