$2018 GRM challenge turbo miata build. with added insanity.
#101
Did the PO have a sway bar fetish?
Congrats on the pickup. That FM manifold is newer than mine, but you have remnants of a circa 2000 turbo kit on the intake side. I'm currently running that IC setup on my car (planning to upgrade at some point). Mine came with the same boost gauge and BOV as well.
The manifold looks like a VICS which would be stock for a 99/00, but I have no idea what the pipe/tube with the hose barbs is. Maybe some type of pre-turbo oil cooler?

Thanks for the feedback on the rest! I really, really appreciate it. The extra pipe is a fuel rail, that was apparently controlled by the early extra ecu to add fuel as needed for boost. Im debating seeing if i can reuse it as meth injection....
#102
For sure, if you have any more questions about the setup feel free to shoot them my way or checkout my build thread.
I was curious if that was a fuel rail. I'm surprised to see hose barbs on the ends considering the NB uses those pre bent nylon hoses. Also strange that it's so far from where the stock fuel rail sits. Was it just sitting there for the photo?

Nope. Welded bungs and mounts into the intake with what appears to be ford injectors. Not sure how it was plumbed back then, as i don't remember the details from tne old voodoo kit documentation i found. It was just odd, but i have it now, and with the aem fic6 its better than the voodoo anyway!
I need to get caught up on updates. Just hasn't been enough hours in the day.....

In the olden days, you'd run a factory ECU and factory injectors, which all stayed happy. When an aftermarket MAP sensor saw boost, it'd add fuel with the secondary injectors on top of the factory ones. It's overly complicated and standalones and larger injectors are far superior, not to mention they're injecting in a terrible location, but there ya go.
OP, you've got way more time on your hands than me if you're tackling that project, the mani/turbo/dp are about the only thing that wouldn't be thrown away if it were me, but my interest is peaked, I'm excited to see how quickly you turn this one around.

After unloading the turbo donor, and taking stock, I went ahead and cleaned it up before doing much. I hate getting dirty. It actually cleaned up nicely, and fairly easily. Little Castrol Superclean and a garden hose took care of the worst of it for round one.
20240527_085544 by Michael Crawford, on Flickr
I then went ahead and pulled apart the megasquirt to see what it actually is. Still not quite sure, but its ms2 based with the sequential injector driver. It was am assemble it yourself setup from DIYAUTOTUNE. Other than that, not quite sure how to proceed with it, or if I even want to, honestly. I’ve had horrible experiences with megasquirt in the past, so I’m more than slightly hesitant. And the AEM FIC-6 that’s in the car works well so far.
20240528_072228 by Michael Crawford, on Flickr
After that, I decided that I needed to get this thing running/driving/making boost for testing purposes. To that end, I cut off the really jagged metal up front down to the bent, rusty and twisted frame rails. Then, pulled my scratch and dent mishimoto radiator out of storage (bought for the green car as that one has finally sprung a leak after all these years) and hooked it up. Mounted via zip ties to a 1x1 tube welded to the frame rails. Then, used some 1 inch flat stock bent and tapped into holes where the fans would mount as additional support to the zip ties. Hooked up the original radiator hoses, filled with water, and pressure tested. One turbo line leaked under pressure, so it was shortened and everything held pressure.
20240531_183222 by Michael Crawford, on Flickr
For the intake tract, I used free range ebay 2 inch tubing and couplers to a fiesta st intercooler I had kicking around. Held in with zip ties no less! Outlet side is 2.5 to the throttle body, and the recirc valve teed in properly. Had to order one reducer and one t coupler. Otherwise, had all the stuff on the shelf in parts that had been given to me over the years by other $2000 challenge competitors during garage cleanouts. The whole works is stupid ugly, but its functional enough for testing. Which I did.

20240603_073152 by Michael Crawford, on Flickr
Lastly, I grabbed a fan from a wrecked dart, wired it into the headlight socket so I could turn it on with the headlight switch, and retained it with more zipties.
20240605_193113 by Michael Crawford, on Flickr
The first test spiked boost pressure to max on the gauge. It was then that I realized that the wastegate wasn’t plumbed to anything and the recirc valve is not the same thing as a blowoff valve or wastegate. See, I’m still very new to turbos (only other was that turbo baja I just fixed and sold). Gently drove it home, t-d into the vacuum line to the gauge and ran one to the wastegate. Next drive around the block showed 10psi max. according to the PO, its tuned for 15. The 10psi lap showed some nasty vibrations, a misfire, very darty and twitchy chassis behavior, and glass flecks blowing in my eyes. So the alignment was eyeballed (seriously toed out in the wreck), taped the windshield, and swapped on my k1s and rivals to eliminate wheel and tire issues for vibration (didn’t fix it. think I know why I got a driveshaft with the car), I also ordered a set of spark plug wires.
It drove shockingly well for a balled up parts car.
there’s some noise in the alternator drive, and the power steering leaks from the return side, but she’s healthy enough. And faster than the v6. And just brings my fat *** some joy. So, it checks all the boxes of being worth it to swap.
Next up is the start of a WHOLE lot of work.

So the next order of business was listing the things I wasn’t going to need, and starting to remove them. Things like the boss frog roll bar, v6 drivetrain, red car convertible top, black interior, etc. I will only not below what counts as challenge budget recoup, not everything I made money on. Reason being, I don’t want to confuse things for this challenge run. I aim to keep my budgeting and documentation above reproach.
The red car had the top and center console sold for 300, the seats sold for 300, the 13x8 wheels sold for 75.

Green car had the boss frog rollbar sold, the seats sold, the projector headlights sold, and the v6 drivetrain sold. None count for budget.

Theres a LOT of work, both in the creation of and removal of parts in these pictures. Its definitely bittersweet to see that many years of effort go, but I know its for the best long term in what I want to own.
So, I now have the running and moving under its own power parts car, and the seam welded and stiffened roller of a green car. The green car needs a lot of cleaning before I go any further, and I will repaint the engine bay and underside, patch the trans tunnel and floors where the rollbar lands, and probably repaint the shell as well. Then I can swap the turbo drivetrain over. After cleaning and painting of course.
Anyway, lets discuss budget. As it stands, we are here:

I have most of what I need for a challenge run, and recoup left to gain, as well as money left to spend.
Until next time, friends.

Budget update first
Previous total:1220.87 with 1625 recoup
New money:
150: Na fiberglass widebody kit that I traded for damaged nb2 bumper and headlights, front k frame, ppf, old Kenwood head unit, and a strut tower bar.
100: (rough estimates) ½ gallon epoxy primer, ½ gallon clear, ½ gallon 2k primer, ¼ gallon Bondo, 1/3 can reducer
100: nb2 surfboard seats I had bought at the challenge last year
10: heavy and ugly ICW 15x6.5 wheels from wheelsmithy with tires old enough to drink
Sold woodgrain ebrake for 30
Sold spindles and suspension arms to wheelsmithy for 75
New totals: 1325.87 with 1880 recoup
Since we left off, I’ve been a bit busy. Like a cat scratching for a place to crap on concrete.
First and foremost, I did a paintjob on a 1959 tr3a while rehabbing an 87 suburban. These were the last two OPC’s I had agreed to, and I’m glad they’re done.

I bought the leftover materials from him to use on the challenge car for $100. He tried to give them to me, but that violates the rules. I couldn’t make him take more. Believe me, I tried.
While talking about procurement, I bought a set of wheels, as I no longer had any in the budget. Don’t like them cosmetically, they’re heavy and narrow, but they were CHEAP. Wheelsmithy from GRM sold them to me. They came on his Miata, and he couldn’t find anyone to take them for free for the last few years despite his best efforts. So, I paid him! They’re bound to get way cooler with some effort and paint, but I don’t know how yet. Feel free to give me ideas.
20240629_205344 by Michael Crawford, on Flickr
After the triumph and suburban were done, I moved onto the welding that needed to be done at dad’s place where I had the good welder. The turbo car has some hacked up sections of frame rail to provide a minimum of clearance to the turbo and downpipe, so I needed to do something similar in the green car. My solution needed to be more elegant, because I’m making a nice car this time.
20240805_171216 by Michael Crawford, on Flickr
My solution was to cut he pinch weld off the driver’s side, and notch the wing some more. This should give me all the clearance I should need, and even allow for a fairly simple 3-inch downpipe should I desire in the future.
20240804_143944 by Michael Crawford, on Flickr
20240810_160333 by Michael Crawford, on Flickr
Then moved onto the trans tunnel. It had been butchered by yours truly to make the t5 shifter fit, and I wanted to be able to make the stock rubber boot bolt in again. Cut a chunk of trans tunnel from a rusty Miata headed to the scrapper, and fiddlefarted around enough to make a patch that fit well enough to get welded in.
20240810_140629 by Michael Crawford, on Flickr
20240810_160259 by Michael Crawford, on Flickr
We then got the car outside for a little cleaning. See, it was filthy from being used as a race car, and from being a Miata before that. So, Castrol super clean and the pressure washer came into play.

The white has aged like milk, and is flaking off. Its going black. I also think I’m cutting the angle welded to the subframe connectors off, as it no longer as a butterfly brace to mount there. Get the out of the way for something better.
I’ve been working on cleaning up the engine bay in preparation for blasting and painting it. that means grinding down all the seam welds, removing sloppy seam sealer, stc. Again, the white aged poorly, and previous me left a lot of work for current me.
20240913_185338 by Michael Crawford, on Flickr
Once I think its ground well enough, I’m spraying some gloss bright paint on it. best way I’ve found to see what it will actually look like when its painted, as ground and wire brushed is perfectly camaflouged. The spray paint highlights it very nicely so I can see what I need to keep working.

20240913_185315 by Michael Crawford, on Flickr
I’m also working on repairing the hardtop, even though that’s not challenge work. It is work that needs done, and while my shop is trashed it’s a good time.
I started by getting the rear latched epoxied back in after cleaning all the jagged and fibrous wreckage out, and managed to nail the placement dead on.

Moved onto the sides, where I opened the cracks with my Dremel and carbide burr, followed by digging deep with a 40-grit flap wheel, feathering with an 89 grit DA, then five layers of woven feverless cloth and epoxy resin. Once this is all done, I can flip it over, reinforce the rear latches, and chase all the cracks on the internal structure. Then ill feel OK about hanging It on the wall out of the way for a while.

If anyone is willing, could you photoshop the colors onto the red car below? Same body kit, bumpers, wheels, etc. as my car.

Great update, glad to see the car making progress!
I'm trying to imagine the blue and am struggling with it as well. The green is easy to see since it's somewhat close to the BRG from the factory. I think that would be a pretty safe bet.
Personally I might lean towards a slightly brighter blue, but I'm far from a paint aficionado.
