Fixed. Side draft, not down draft.

Moved the pressure gauge, made the manifold hoses. Everything's done in push lock -6 AN. Weber inlet ports, for what it's worth, are 12mm x 1.5mm thread pitch.

Depending on how annoyed I get, I may heat shrink the ends to clean up the look a tad.

Final setup. Got my velocity stacks, got my fuel filter, got all the fittings, all the hose, just need to wrap up three final details - electrical power for the pump, a blockoff plate for my mechanical fuel pump, and insulated hose clamps for the long spans.

Changes, of course.





1) 90 fitting at the firewall side of the fuel rail.
2) need to shorten the throttle shaft.

Done fixed up the tubes and stuff.





Because I wasn't doing enough, I ordered Hella E code headlights, too. Got the headlights in, got the relay sub-harness made, got the initial cut at running, then ordered 50F9 idle jets to replace the 45F9 jets in 'em from the builder.

Before I got them, they'd been sitting on a shelf for a while, so I had to coax them back to life, and the needle valve in the middle carb's float chamber was very firmly stuck for some reason. But all that's fixed now, and it runs, except for a flat spot at around 2500 where the carbs should smoothly pass from the progression circuit to the main circuit (it leans out and bogs). But that's what the richer idle jets are for.

Once the mains come in, it's a revelation, and it pulls hard straight to 7000.

Thanks!

I discovered one small issue that I'll need to correct, in that the tank vent line is now kinked, and not letting me fill the gas tank beyond about 2/3rds, but I think I can solve that with one of those anti-collapse springs that set inside hoses (I just hope they make 'em in 5/8").

It always amused me that the Datsun purists who only want Japanese wheels from Enkei or SSR don't bat an eyelash about pulling the trigger on a set of Italian carburetors.

But, now I've got Italian carbs on this one. And the other one's got German wheels and Italian brakes.

Moved on to a "get some tunes in the car" project.

The stock radio is AM, powers one speaker (to the tune of 4W), has a weird-ass rocker switch in the dash to raise and lower the antenna, isn't built to any sort of DIN standard, and is super duper expensive. Mine works perfectly, and it's a nice visual piece in the dash, so I wanted to keep it, and keep it working.

So, with that in mind, I set out to make a stealth setup for the car. It will stream bluetooth from the phone, will be on when the radio is off, will add a right speaker in addition to a decent left, and won't be visible externally.

It's kind of a tight set of conditions, and it made for a couple tradeoffs that compromise sound quality a little bit. The biggest tradeoff is that the stock brackets only have room for a 5.25" speaker, and a maximum depth of a little over 2". So, I bought Match MS5x speakers.

I bought a Sure bluetooth module to match up to a small class D amp that I bought from gee, which is a basic 2x50W unit that has a little 12-24V stepup circuit in front of it.

Here's the initial "will it work" board:


I didn't want to modify the radio, because like I said, it's super expensive, but I really needed a radio-switched 12V. So, I looked at the service manual (which included a complete circuit diagram), took a deep breath, and heated up the soldering iron.

I added the blue wire in the picture:


Fortunately, there was a spare output in the bulkhead, so I didn't even have to mod the case.


I repurposed the antenna harness, so that i could get ignition and radio-switched power to the hatch without having to run new wires, which had the added bonus of allowing me to use a modern power antenna.


I bodged up a schematic, that used one more relay than necessary, but I was a little worried about drawing too much through the radio +12V. Two constraints that you don't normally have to deal with that I did are: 1) backfeeding the amp usually doesn't do anything, but it has a history of blowing up the Hitachi radios, so I needed to switch speaker outputs according to which is on. Also, the amp I got doesn't like being on without having a load on the speaker terminals, so when the radio is on, the amp must be off.


Then I started assembling.


Finished:


Right speaker, installed in all the mess of hoses that Nissan decided was necessary to handle slosh and vapor in the fuel tank. This is just a spare left bracket, with the studs pounded out and new screws installed:


Amp in place, in the compartment behind the Driver's seat.


Test! Because the amp is from a Canadian, I had to make its first play Tom Sawyer.

I did more arts and crafts.

Pulled out my worthless spare (I carry a patch kit and compressor anyhow, since the spare won't clear my big brakes).




Glassed in the well.


Put a PG DVC 10" low-profile sub in, flush with the surface.


Not shown: making a 26" diameter ring for connecting the top to the glass tub, or making the 12" diameter ring for flush-mounting the sub to the top.


Amp, mounted under the driver's seat. The wire split goes to the other amp, in the behind-the-seat compartment on the driver's side.


Wrapped up, all stealthy. You can't see that it's installed, and the original AM still works fine with the one speaker on the DS of the hatch. The only outward indication that it's working at all is the fact that the antenna switch isn't hooked up to anything anymore. Forgive the handprints, I was excited, and hadn't cleaned up yet.

I also replaced the carpet liner, since that brown shit was fuckin' disintegrating.
