so funny you bring this up. I've been thinking about how I want to go about doing this, and it's the main reason i haven't powder coated the UIM yet. So far as I can tell the Cosmo doesn't have a brake booster and such no provisions for running a vac line to one. I've been thinking this little depression in the casting would be a good place to drill and tap for a barb fitting. it would be a straight shot right to the booster.
In other news. fuel system is pretty much complete. The last piece of the puzzle was the fuel pump. I got one of the aeromotive 340 stealth in tank pump. I think we'll all agree that running an aftermarket pump on the stock wiring is like playing with fire. In fact the wiring on my stock harness was already showing signs of overheating on the stock pump. So I went on the hunt for passthru connectors. I just can't believe the price companies pay for a stud and 2 pieces of teflon. So I opted to be cheap and make my own. Here's the studs before nickel plating:
after nickel plating and with the rest of the fabricated parts.
all installed
Some sharpie marker makes the wiring clear.
all installed with new soft lines. Just need to wire it up when I do the ECU wiring.

Back with more fun. The RW kit, is showing it's price tag a little. Went to go mount the fans to the radiator, and NOTHING lined up.
The pins didn't line up, nor would they EVER fit in those openings.
No way to get the fans over the inlet neck, and even if they did not a single bolt hole lined up
So I ended up lopping off the bottom tab mounts and extending the openings in the fan shroud to fit. I made a new bracket to secure the bottom of the fans It had to be removable so you can slide the fans up under the inlet neck. Not fancy, but it actually works.
Also I fully intend on having working AC, so I added a few mounts for an RX8 condenser

small weekend update. I'm waiting for quite a few parts to come in so it was chance to get a few small things done. Finally got the FPR bracket machined.
Fits like a glove.
The other thing was to relocate the relay box. I'll have to relocate the battery anyway, so this seemed like a good spot for it. It should be out of the way for the water pump lines. Still playing around with the mounting brackets. I'm hoping I can get the rear mount to hold the fuse block as well.
Front mount done with the harness re routed.

cool things happening this week. I decided to get serious about mounting the PS and AC pumps. The 3d printed parts looked pretty good so I pulled the trigger on some laser cut parts and machined the other brackets. One thing I've learned about ordering parts, is always order 2 in case you bugger up the first one.
test fit went well so it was time to powder coat and test fit the parts. AC installed and so is the PS bracket.
PS installed.
The other cool thing, is I got that 4" to 3" 90 degree adapter made. Well in reality I didn't make it, and I'll give @Pete_89T2 the credit for the idea. I decided to see how much having the part 3d printed in metal would be. Checked Xeometry and it was $1000 which was very disheartening, but for sh*ts and giggles, decided to check a few other places and low and behold, it was actually cheaper than i can but the raw stock if I wanted to machine it. Behold the 3d printed goodness...
welds great too. the material is advertised as being as close to 6061 as you can get printing.
this...is going to be good....

Looking excellent as always! Might have missed it - is that the Rx8 AC compressor?
Also, how was Xometry to work with? I have used Sendcutsend for a bunch of sheet parts, but have been wanting to go further down the rabbit hole with some CNC'd 3D goodness and they seem to be the ones to go with.

I did not end up ordering it from xeometry. They were 10X the price of the other places i looked. PCBway had good prices, but I ended up ordering from in3dtec.
I'll also say, if you're parts are small-ish, i'm always looking for fun parts to machine

weekend update. Got a good amount of things addressed.
batter relocation started. I don't generally like buying kits, but the JP3 kit did everything that I wanted right out of the box.
PS and AC mount is just about done
now with idler pulleys form a Mazda5.
finally got the turbo and heater core coolant return hoses run to the radiator
Also got the water pump roughly where I want it. Still need to fab a mount, but it's going to be here-ish
Just enough room to sneak the hose thru
Also got the water pump adapter started. The intent will be to machine it all and weld it together.
Here's what it's likely to look like when it's all done.
Also got to something I've been putting off for far too long. Mounting the coil packs. Here's my best solution so far. Will require a custom oil filler neck, but that's not so bad.
Oh....and I got the ECU on order. Went with the Link G4X fury. Things are starting to come together!

thanks for the kind words everyone.
Not much progress. Still trying to get the coils mounted. The GM DBW throttle body in conjunction with the Excessive LIM don't leave tons of room for anything so it's proving to be a bit more involved than I was hoping, but that's how these types of projects go. I just printed a new itteration of the mounting bracket last night, so maybe today I'll have a solution that works....fingers crossed.
I'm also a bit of a dumbass and wasn't keeping an eye on my welding gas bottle level and ran out of gas mid-weld while attaching the couplers to the intercooler. Of course it's a highly visible area and it looks terrible now, so there's that....haha
Also still up in the air....
- coolant line routing/ swirl pot fab
- AC line routing
- Alternator mounting and adjusting, and by extension serpentine belt length.
- intake and intercooler pipe routing
- and of course all the wiring, including finishing up the battery relocation.
