Alpine e30 progress/build thread

Question on that expansion tank. Does the high up hose connection, which I assume comes from the small hose high on the radiator, have an internal tube going to the bottom of the tank? Or is it just a hole into the tank? I've looked at those and never gotten a good answer. The stock tanks have that bleed line go down to the bottom of the reservoir to prevent air from going back into the top of the radiator every time the engine cools.

that headlight cover looks awesome.
you're getting alarmingly close to running/driving e30 land.
ill need to get stickier tires for autox this year so you don't make me look a fool.
Definitely feeling more confident about getting it out this summer! There will certainly be a learning curve with about double the power... no more on/off gas pedal haha

To be honest, I completely forgot about that one... whoops. I'm 95% sure it doesn't have an internal pipe running down to the bottom. I'm not convinced it is 100% necessary as the air might just bleed right back out next time it heats up, but I do think it would be best practice to have that feature so I am looking into ways to add it. I am thinking of using a barbed bulkhead connector tapped into a plug on that port, then fit the hose on through the top hole.

Right, it might bleed out, I'm not sure how I feel about doing that.
I was looking for a tank with a small connection down low for the radiator bleed line, it doesn't really matter whether it comes in the top and has a tube to the bottom or just comes in down low as long as it isn't too near the larger hose where coolant gets sucked back in so that any bubbles can rise out of the liquid.

Agreed, I would definitely prefer to have the peace of mind that the bleed is 'permanent'. I ordered some parts to fit an internal tube with the goal being putting the hose end about 1/4 of the way from the bottom of the tank, since I'd like to fill it around 1/2-2/3 of the way full.

Let us know how it works out. I would love to replace my plastic coolant tank with an aluminum one, and also need something for the van project. Although with that I can easily mount the tank well higher than the top of the radiator so it shouldn't be an issue.

Making progress!
Installed a new E30 CSB on the lowish mile E36 M3 driveshaft I picked up a while back and got it installed in the car with a new gumbo
I liked @straight6pwr's method of removing the AC evaporator core so I did the same. I blocked off the opening in the side cover with a piece of plastic from an old tool case I don't use and seam sealed it in place. The core had tons of junk in it so I should get a lot more air flow now too.
Spent the rest of the weekend doing a bunch of wiring. I made some changes to the radiator fan wiring that was previously always on with the ignition and added a manual override switch in the center console and a 91C temp switch in the radiator. I also completed the wiring for the VDO water temp/oil temp/oil pressure gauges. The backlight/dimming works well and at least the oil pressure gauge is working, haven't gotten any heat into it to test the other two. I also started the Hella Sharptone horn wiring but couldn't get too far as I don't have a relay for it yet.
I also continued with the center console. The console I have is from an early model car so I had to make some modifications for the knee bolster mounts and such. There is a large cutout on the side as well as a notch cut into the rib that runs along underneath the ashtray area. I also removed all the insulation on the back as it seemed to cause some fit issues. The original console is on top, new one on the bottom.
Before:
After:
And installed! Looks great with the gauges in there, fan switch works well too. I still haven't wired the e36 switches as I don't have the right ones, but left them in to fill the holes.
The only issue is the console still isn't sitting right so I'm going to have to pull it back out again and do some more investigating.
Getting closer!

Getting nothing done because I'm never home, but I did solve one very important issue that was pretty critical to making it to the picnic:
I replaced the rusting screws holding on my steering wheel with some neat raw titanium ones. Stainless was too bright and I didn't trust the strength of anodized aluminum. Titanium has this flat dark gray color that looks really nice and wont rust or tarnish like steel. Plus the 0.5oz weight savings that high up will drop the CG and give me the edge in autocross.
As far as actually making it to the picnic I think I have all the parts to get it done either in my garage or in the mail, now I just need to find the time to get it all buttoned up.

You know it's okay to ask for help.

Don't worry I do! If it starts getting into real-deal crunch time I will for sure be planning a "help plz" party at my garage

Didn't take any pictures, but got a few things done last night!
Brakes are bled! Turns out I didn't have a container of ATE Type 200 like I thought, but I did have an unopened can of ATE Super Blue so I now have a fresh fill of fancy blue brake fluid. The new larger master cylinder pushes a lot more fluid and feels really nice, though I haven't tried it with the engine running.
I don't have the rebuilt 3.15 LSD yet so I installed the original small case 4.10 open diff and finished the driveshaft and axle installation. This is mostly to facilitate the exhaust fabrication that I am hoping to get started on very soon. The drive-train is basically functional short of torquing the axle flanges and bleeding the clutch, so that's exciting.
Current to-do list for making it to the picnic (22 days remaining):
- Bleed clutch
- Pull headers to lengthen O2 sensor plug wires, reinstall headers
- Fabricate exhaust
- Weld skid plate mounts to chassis and install skid plate
- Finish coolant tank internal hose, mount tank
- Install/wire coolant temp switch for electric fan
- Bleed cooling system
- Fabricate catch can mount, route hoses
- Fabricate intake/filter support
- Reinstall interior pieces
- Reinstall hood/grilles
- Change trans fluid

in order to get you to the picnic, i've audited your list to only the bare minimum.
- Bleed clutch
- Pull headers to lengthen O2 sensor plug wires, reinstall headers
- Fabricate exhaust
- Weld skid plate mounts to chassis and install skid plate
- Finish coolant tank internal hose, mount tank
- Install/wire coolant temp switch for electric fan
- Bleed cooling system
- Fabricate catch can mount, route hoses
- Fabricate intake/filter support
- Reinstall interior pieces
- Reinstall hood/grilles
- Change trans fluid
I expect you'll show up in a blaze of glory - with open-header flames, fuh-raz no hood style, oil spewing from your cracked oil pan and catch can hoses, and a steaming engine hotter than two mice fornicating in a sock.
but you'll be there.

Making it to the picnic is absolutely a badge of honor . I only had a handful of miles on the swapped E30 last year when I took it to the picnic. Driving home from it was some mixed feels though. Strong sense of victory and accomplishment, but knowing deep down inside that my turn with that car was over and it was time to pass the torch. You have picked a great engine swap that not a lot of people have done (compared to the usual X50/X52) so I am really interested to hopefully get a ride in it sometime

If we're going that route I might as well skip bleeding the clutch, just start it in gear and don't stop till I get there!

Its a perfect event to aim for! E30's are the focus of the show, it's in the spring so I then have the whole summer to enjoy my car, and it's not so early in the year that I'm are working in -10F weather to get there. Plus, having a deadline I'm motivated to hit means I'm more likely to put in the hours needed to get it done. I'm really excited to get it on the road, I really hope it lives up to my expectations. You are more than welcome to come for a ride once I've got it going!

More done after work yesterday, forgot pictures again.
- Pulled and re-installed the center console without the spacer that was under the rear mount point on the original console, it fits way better now with no huge gap between the bottom edges and the carpet. Reinstalled the rear console as well.
- Installed a 91C temperature switch (BMW part number 61311364272) in the radiator and completed the fan wiring. The M54 operates around 96F based on what I have found so this should offer good protection if the radiator starts getting heat soaked while idling/etc. I can also manually override from a switch in the console if I am at an autocross/stuck in traffic on a hot day/etc. Eventually I'd like to add a 'fan on' indicator light somewhere, but that can happen after the picnic.
- Pulled the headers to lengthen the O2 sensor harnesses. I've got a pair of junk e36 sensors with much longer wires that I can steal the wire/plug/sheathing from so I only have to make one splice in each wire. Hoping to get that done this weekend so I can reinstall and start on the exhaust.
