Luna: The cause of, and solution to, all of my problems

Recommended Posts

Bench bled the master

33132792100_1af30eda20_k.jpg

Installed...

32673068714_1f7e00c1d1_k.jpg

Tomorrow I will check for leaks, and jack the car up in preparation for bleeding the system again.


Then I'll spend a couple days under the car dialing suspension/alignment settings, installing CVs, filling the diff, etc.....

Then If I've made it that far successfully, then we go about plugging the computer in and see what it does.


C'mon brakes...no leaks.

Still chasing brake system leaks......The new master is leaking at the adapters for my OEM metric brake lines.....so I'm going to swap in the 3/16 sae fittings - remake the lines (2x 12" sections) - and reinstall..


Other than that...I've been busy.



CVs are installed.

33500247800_67d1b71ecb_k.jpg

33843789476_4e44635ac8_k.jpg

Differential is filled.

33154214204_3af76e9ae7_k.jpg

I wrestled with the tail light panels.

"perfect fit" ...yeah....okay.

33985272025_e9cdb150db_k.jpg

After some chopping...

33985260595_5c2eb9d1dd_k.jpg

I was able to get them mounted. These will work for now, but I'll probably make a set more to my standards.

33867823001_81c46fddf6_k.jpg

33866552151_52db4fd95e_k.jpg


I confirmed timing, and installed the nice valve cover, coils, and other remaining engine components.

33948229251_2aa403f1f8_k.jpg

The car fired right up, but is still running very lean, and hunting at idle. Looks just like a vacuum leak.....But, I've taken the intake manifold off a couple times, and believe that it is not a vacuum leak, but instead just insufficient fueling..When I rev the car, the mixture enriches, and will rev very strong and responsive. No hesitation. Only at idle does it hunt......But the serial to usb cable I use to communicate to megasquirt died, and my laptop won't keep a battery charge off of the charger, so I am waiting on some goodies from EFI Analytics - A bluetooth transmitter to transmit automatically to the Shadow Dash app on my tablet. So that's cool. Not as cool as an idling car, but pretty cool nonetheless. It'll be nice not being limited by 2 feet of usb cable.

So once I fix the leak(s) the next step is to test that the driveline works. Currently, I can't get the car in first. I guess I need to investigate the slave cylinder hydraulics.


 
In other, less car related, news I painted the garage. And remade some Whaler pieces that I broke, stupidly, last summer. Getting all the boats ready for Spring.

33177347614_46d18f1e20_k.jpg

33897186192_02988caa72_k.jpg


My brother and I broke the seat back on our Whaler last season. He went airborne and fell into the seat back, snapping it off at the handle holes....This was on its maiden voyage of last year.

So this has bugged the **** out of me since I restored the console.

The old epoxied piece that got me through last season. I used this as a jig for the router.

33670020382_fdba60b1f0_k.jpg

I bought a beautiful 10' long solid mahogany plank and used it as the stock for both a seat back, and a replacement (non plywood) bow locker hatch.

33826178055_90898e70d0_k.jpg

No more handle holes. Or as I call it, "fall into proof"

33441482780_7faa28b980_k.jpg

Bow locker replacement. Unique looking grain. I like it.

33012833163_cdfe2d0938_k.jpg

Chris Craft Mahogany filler stain

33842961015_e5cb60e8f1_k.jpg

And then 6 coats of Epifanes varnish. The first coat is thinned 50% with brushing liquid. The second is thinned 25% and the final coats are thinned at around 10%. The last coat is thinned at 50% once again to really flow nice. Sanded with 220-320 between coats.

33150927363_0d643afc4d_k.jpg

33834045611_45bc28e60b_k.jpg

still need to tuck those wires...

Next: the whole boat needs a buff, and Ptef treatment. Then she is getting launched. Not too shabby for being 47 years old. Gotta love a classic.



Also, I was given a drone! So look forward to seeing some drone stuff. This will make my sailing and car videos much better.

33077425724_282c970245_k.jpg

The following video is garbage, literally my first flight, in whatever lighting was available. Mainly a test of the gimbal, which works really well.  I've learned so much since this. Very fun!




so stay tuned for that! Edited by OldAndyAndTheSea

Sorry guys...I suck.

 

 

 

 

 

...Hey, remember me?

 


Well lots has changed since my last update. Life got crazy, I fell away for a while. I apologize.

24773612907_931e0c1181_z.jpg


But I am back now with a hot fresh update!


Since you have last seen me...

 


The car got an air dam. I painted it with black base coat and satin clear.

37820850311_2218fbb31d_k.jpg

37562488000_6b68dc6170_k.jpg

38148864901_c0db398c58_k.jpg

Took some fiddling and trimming to get the right fitment with those damn 17" wheels.

37820844541_9fbd40108c_k.jpg


And upon taking this photo I decided to finally address my bumper issues.

37562486140_9decd7fd92_k.jpg


So I straightened the all sorts of messed up rear bumper (thanks to me backing into my tractor years ago, but hey that's what it is there for, right? haha)

Welded up any holes, and ground them smooth. Body worked and painted the same black and satin clear as the air dam.

39641934361_51f41b459a_k.jpg

24296993748_a494a3e48e_k.jpg

Now it was time to address the front. The car, in my care, has never had a front bumper. I was excited to change this, and really finish off the front of the car.

Over the years of parts hording I accumulated a collection of various twisted, rusted, dented up bumpers from cars I have parted out. So I decided to take the best of the bunch and run with it.

....making my version of a "euro" bumper. I like how it turned out.

38933464464_c5127a9543_k.jpg

27863753159_1211c7c7b4_k.jpg

Mounted - The car suddenly got mean looking.

38117422212_1db5c4d030_k.jpg

38117417102_894d05144b_k.jpg

38117417152_2765322d34_k.jpg

And I finished stupid odds and ends like

Figuring out why it wouldn't go into gear.
Adjusting the clutch master cylinder.
Modifying the 4 speed shifter to work with my 5 speed transmission.
Sorting the brake issues....things like that.

24773538537_8281134c38_z.jpg


Now it was finally back to being a car, basically. Just not quite road ready....


....then right before winter hit - this happened.

24773610807_0ca1c97d31_z.jpg

I took the car to BERG Racing in Rochester to finally dyno tune, and corner balance the car - things I couldn't do in my shop. I had no idea these guys existed....and if I had I probably would not have built my system myself....They actually reached out to me, over a random facebook post, and told me to bring the car in for finalizing. I gladly obliged, as this now freed up valuable space in my garage to do more volatile work, without fear of hurting the 240. These guys are absolutely the best I have ever dealt with. I can't even express...

So a couple days ago this happened.

 

38933527954_7a52750265_k.jpg

[25 second video - click the following picture]

39643706111_959ccd5ca9_z.jpg

 

38933528584_f7191c63c6_h.jpg

 

27863839139_66d132ff27_b.jpg

These are exactly the numbers I was expecting. I am running only 5-6psi boost (stock wastegate setting) making as much power to the wheels as a stock l28et (the lower compression turbo version) makes at the crank, supposedly. This shows the difference between converting an N/A higher compression motor and sourcing out the lower compression "true" turbo motor. Also means my motor is still healthy. It means I am on the right track.

 

The engine is barely trying, at only 5 psi, and makes 174hp and 218 foot pounds of torque, on a very safe, conservative, tune. I will very easily achieve my final goal of around 300/300 once I upgrade my turbo. In the meantime I am going to get a baseline butt dyno for the car with almost 100 pounds more torque than last time I drove it. Once I get that baseline, I'll keep turning the boost up on the tiny t3 until I stop going faster, and start losing traction, and see what I can eek out of the turbo in the meantime. I imagine it will live at 240-250hp fairly well, but anything above that will start to fatigue the turbo I think.

 

Right now I'm sourcing a gt3071r with a .63 hotside for the future. That'll do me nicely I imagine.


Then the car got aligned and corner balanced.

 

38933540364_bd622d5cf9_b.jpg

38933538414_fd0e7bea7b_k.jpg

 

I was very excited to see what it weighs. My goal was always to come in at under stock weight (2300-2400), after all of my modifications and additions to the car. I made that goal, and I know this is just the beginning for that. There is so much weight to be saved all over.....my wheels alone...the rotating mass...I mean c'mon. My next goal is 2200 with me and a roll bar.


So yeah. 2261. Good starting point. I'm happy. Challenge accepted.

Currently the car is still in Rochester, and with the weather I don't foresee me trailering the car back anytime soon. Ideally I am going to drive it home, so I will register the car and wait for the appropriate window of time to get it back here.

I can use my garage to generate income in the interim. Although I am really really really REALLY excited to finally button the last things up. Like finish tucking wires, putting the front end back together, installing my tow hooks, lots of little things that will now be super enjoyable.

But basically....

 

Insert Mike's meme

 

38745674125_a12dbf8bcd_b.jpg

 


2018 is the year people.


If you are reading this, I truly appreciate you following along.


Cheers.

How the hell did you get it to weigh that little? Granted it has no hood, airdam, or bumper in that pic, but still. That's a good 200lbs lighter than I would've expected. Empty tank? A full tank would add about 100lbs. With a turbo swap and associated parts, heavy (?) seats, big heavy wheels, R200 diff, disc brakes, etc. I never would've guessed that weight. 2260 is about what a stock series one would weigh with no fuel.

 

Well anyway, everything looks good!

 

Also, I spy another Z. What's up with that?

Carbon parts really help when they are truly carbon. I saved a lot of weight in my dash, and all my little widgets here and there. Car was fully stripped, so it doesn't have much material weight on it....I dunno though....saving weight has been a huge priority of mine. 

 

Car has like 8 gallons of fuel in it currently. And the hood (11 pound composite hood) was on the car for weighing. Air dam and front bumper weigh about 15 pounds together.

 

I have been trying really hard to not add any weight, and save ounces wherever I could easily. Those apparently have added up nicely over time. I am pleased, because I know this is just the beginning.

 

2000lbs is the goal. Hopefully with me in it. But I am going to add a roll bar.....ugh...so first goal is to keep the same weight I have currently, after adding a roll bar.

 

This is really fun for me. Saving weight is my specialty. Now I get to do it, and see return, on cars!

 

 

 

Other Z is a 260 parts car that I sold actually. However the buyer of that car will most likely be dropping off his 280z to be painted. That is one reason for not wanting my 240 back in the garage quite yet, despite wanting to work on it so badly.

Hey Old Andy! I was just taking a look over your build and it looks great. Mind if i ask what pillar pod you modified to fit the z? thanks so much!

 

Hey thanks! The A pillar pod is from a first generation Mazda Miata  (NA).

 

I have yet to truly modify mine to fit - it will take some "massaging" to say the least.

it's the one made by Xenon. Made of urethane.

 

I'm going to be making a carbon splitter to mount underneath to prevent it from collapsing due to apparent wind at speed.

 

 

Here's one on eBay

She came home last week. The shop wants me to bring the car back as soon as possible, once I clean and sort it out, for a photoshoot. Super Street is the rumor. I don't care either way I just want someone to shoot the car. Needs a paint correction baaaad.


41009714574_2942700c0b_k.jpg

But she wouldn't boost at all, it was running very lean. Idled fine..After a little investigation I discovered the source of the problem.

The trailer ride back over stirred up some **** in the gas tank which proceeded to severely clog one of my fuel filters.

41009714034_cee73f76da_k.jpg

I also developed a couple leaks due to things heating up and cooling back down a few times. Like the rear diff cover needed another go around to stop some seepage, and the turbo oil feed gasket failed, so I made a replacement for that.


41680971001_1b2f9536da_k.jpg


The fuel filter fixed the lean condition, obviously, and the car boosts beautifully. It's a hoot at only 5-6psi out of the tiny t3.

A wonderful starting platform. It really feels like what you'd expect a racecar to feel like on the road. It feels LIGHT. It takes no effort to move itself, and it feels very stiff. I have not come close to losing grip. The car is very planted and balanced. Makes sense....it was corner balanced.

The carbon interior, not being fully installed, doesn't even rattle. I expected it to rattle like a snake, but nope.....a couple loose screws on some plastics in the rear, but the dash is Gerbraltskis. Rock solid. The new 5 speed n/a zx transmission is wonderful.

The rear end does transfer a bit of noise into the cockpit, some of which I will attempt to quell, but otherwise it isn't overly concerning for me.

I LOVE every second of it. It is serious sensory overload. The sound, the look, the feel of being surrounded by carbon....the response....it's the whole package. I am very happy.

40828480605_669cd242b0_k.jpg

 


Now I am putting the car back in the air to confirm all the bolts under the car are still tight. I'm looking at you diff bolts.....axle bolts....lug nuts.

 

It looks like shit now...I can't wait to clean it up a bit.


It's a car again!


Now it's time to make it a better one.


125 miles in. She hits.

Nice plate, and congrats! Super happy for for you!

 

It's been a while coming. And teaching myself has presented a lot of learning curve...but I don't regret any second of it after driving the car. It's all worth it.

nice work indeed.   must be awesome after pretty much making her yourself.

 

tell me, with a t3, when does boost come on?  (rpm-wise)

 

seb

 

yeah, there is very little actual stock Datsun left on this car....I have either touched, redesigned, or upgraded virtually every major component in the car. The ONLY thing I didn't do myself was corner balancing, alignment, and fine tuning the idle on the dyno.

 

otherwise, it's all me.

 

It does feel amazing having done all of the work myself. The car is a constant reminder of how far I've come in all aspects of skill. From painting skill to welding to just general and theoretical automotive knowledge....I am shocked at how far I've come.....I knew very little about cars, aside from an addiction, when I started this project.

 

I also had NO idea this car would potentially gain magazine status.....that's fuckin' nuts.

 

 

On my current setup the car feels supercharged. Full boost (granted, only 5-6psi) hits at right over 2500 rpm, and will pull strong until about 5500 rpm, when the car starts to lose its juice. It wants more boost. But I am being VERY conservative, as this is now my primary daily driver, as I find a suitable replacement for my E30 which was totaled by a snowplow this winter.....RIP girl....I miss you. You deserved better.

 

 

 

 

 

 

 

 

215 miles in. Still a car!  Woot!

Tonight, after work, I decided to putter on the 240.

not having door handles was getting tiresome, so I installed some Porsche RS style handle pulls. I opted for the red set to match the seatbelts, and also for some better visibility for "ohshit!" grabbing. haha

40869208295_26088cf052_k.jpg

I could have mounted them like this.....but that's too easy, and it looks like garbage...

41768760741_1cbf19678c_k.jpg

...so I took it one small step further..Choppity chop chop..

27899804048_54fb4b02dc_k.jpg

I really really really like how they turned out. Exactly what I had hoped for. I will be replacing the temporary fasteners with something a bit more appropriate. These are just to see the proof of concept.

41729434042_784bc661d8_k.jpg

41729397342_af0fe6ae6a_k.jpg


simple. lightweight. clean.


I'm a fan.

 


...also got the rear tow hook bolted in place. The front will take a little finagling, but I'll knock that out in the near future.

Tonight was spent modifying my A pillar gauge pod, preparing it to be flocked.


The gauge pod was originally meant for a NA Mazda Miata, and was much too wide. You could see all my wires with the pod mocked in place.

so out came the heat gun....which worked surprisingly well.

41750921672_f506437f18_k.jpg

Slowly working my way up the lip, molding it to the weatherstrip, and then trimming off any new excess.

41750920882_656f85e435_k.jpg

Looking fairly haggard, but it conforms nicely.

Instead of flocking it today, I decided to do it late last night/early this morning, so it could be curing to the touch when I slept. It's got a couple more hours before I can carefully handle it and install it.

But here are a couple sneak peaks. I forgot how much flocking changes the appearance....all of a sudden this fifteen dollar piece of plastic looks expensive. haha.

39996070750_f29b467339_k.jpg

27934938388_d02c7cd8f5_k.jpg


Yay! Now maybe I can have the car all back together then take it for a ride. The weather isn't terrible today, so I didn't want to waste the day waiting on cure.

I was able to delicately mount it in the car today. Now it can hurry up and cure fully.

And to confirm I put everything back together correctly I started it up and brought it out to the end of the driveway. On display, haha. Being in the sun will speed up the flocking.
