Curly's Garage Sale

curly — Thu, 30 Apr 2026 18:52:44 GMT

doh, posted before I finished typing title, was supposed to say "curly's garage sale" Oh well.

All prices do not include shipping, PM or post here with interest, and I'll get you a quote.

Bunch of random stuff I've accumulated over the years, starting with some Paco Motorsports strong arms. Half contemplating installing these on my car, but I'll still post regardless, $340. Installed once on an occasional track car, never crashed, all hardware included in the baggie. Read more about them here:
https://pacomotorsports.com/collecti...ts/strong-arms

Blackbird Fabworx engine mounts. These are the competition drop mounts for 01-05 oil pans. As far as I know, they can fit 94-00 as well, the oil pan mount will just float in the air, $200. Installed once on an occasional track car, never crashed. Read more about them here:
https://www.good-win-racing.com/Mazd...vzHMgQqAgg4GYI

Kazespec(?) splitter mounts. These were most likely part of an early group by, so not too sure if they're in fact Kazespec, but that's my best guess. They bolt to OEM holes, are made of fairly thick SS. Trace out a birch splitter, bolt these on to it, and voila, splitter. Only other place I could find something really similar is $350, and not exactly the same product, but same shape, $100.

Fidanza adjustable cam gear. Live out your 90's tuner car dreams, $120. Read more about them here:
https://miatadepot.com/products/f?va...xoCBvgQAvD_BwE

And finally, an OEM oil cooler/warmer. Great for bringing cooler oil up to warmer temps to be nice to your engine. Came off a known good engine, I've sonic cleaned it in a purple power solution, rinsed out any grossness out of the water channels, and wrapped it in a snuggly red rag, $100.

Built turbo NA partout (california)

niketh — Sun, 26 Apr 2026 20:35:36 GMT

See my build thread here: https://www.miataturbo.net/diy-turbo-discussion-14/spending-all-my-high-school-income-30-year-old-car-107418/page6/#post1673875

TLDR: Super fun project car I worked on throughout high school and undergrad. Now I have a super fun project to work on in grad school (laser free ion traps!) and don't have the time to keep working on the car. Willing to let everything go for SUPER cheap (everything has less than 1k miles) if it's going to another enthusiast. If someone wants to come take the whole thing, I'd do even cheaper.

1995 NA Chassis
Built 1999 BP: 8.6:1 Supertech, Manley rods, bottom end built by Clark automotive in Cupertino. Billet oil pump, fluiddampr, 1200cc FID injectors, supertech heavy double springs.
Turbo setup: Bofi low mount manifold, efr6258, bofi downpipe mounted to custom 3" catback with big *** muffler (whatever one is heavily recommended on the forum)
MS3PNP, AEM wideband and oil pressure/temperature gauge
Suspension: MeisterR ClubRace 12.5/7 kg coilovers, Advanti Storm S1 15x8 +25 wheels, Continental ECS 205/50/r15 tires
Unicorn: Supermiata super big radiator; this things a beast

I'm sure there's more so feel free to DM me or email @ niketh.keshavan@gmail.com with questions

Supermiata Lightweight Flywheel (aluminum)

Lancefitzgiben — Sun, 19 Apr 2026 17:59:58 GMT

I've got an older style aluminum lightweight flywheel from supermiata. This was in my stock powered '97 for a couple years before I put the K24 in. The clutch lives on with the K24 but this flywheel is of no use to me now - looks like it's in great shape. I would probably replace the pilot bearing but otherwise it's good to go. I'll ship it for $465 obo in the con US.

PPF Delete

mr20turbo — Wed, 15 Apr 2026 21:05:11 GMT

This started as a kmiata NB ppf delete. I pulled the threads out of the original setup and wrecked a few differential housings.

post #142 here:
https://www.miataturbo.net/build-thr...-build-106314/

That got cost prohibitive so I had a new mount cut out of 7075.

Post #147, same thread:
https://www.miataturbo.net/build-thr...-build-106314/

I'd like to get 300 bucks out of this unit that won't have you break a bunch of differential housings. If you happen to have the 6061 mount and want to run big tires I have an additional 7075 mount I had cut I would let go of for 100 bucks. Yes, i know they are new for 299. To that I would say price 7075 and machine time. :)

01-05 SpeedyEFI PNP ecu + EpicEFI Adapter Board

Bloopdog — Sun, 12 Apr 2026 07:21:03 GMT

This works as a pnp for a 01-05 miata. It ran my boosted car well for a year with no issues. I have a few jumpers soldered in, one for the vehicle speed sensor to work well enough for boost by gear- it works but the signal is too noisy for anything other than that.
Has the bluetooth module so you can tune and log over bluetooth, no cable needed.

These get an overly bad rap, if you just want something to learn and run your car, this will do that and more.

I have boost and flex pins soldered in and wired outside the board to easily access. I personally used the flex pin.

It has an stm32 adapter board with epicefi firmware on it (rusefi based) this firmware is very good. I had my car idling insanely well on it, with arguably better/more features than megasquirt. It also is still getting live support and updates, with its own tuning software released and being developed. The adapter board also has sd card logging and an mcu that is miles faster than the ardunio board. - the board has a tune and pinouts on it that fire up the car and works, it needs to be tuned like any other standalone. You will need a 36-2 trigger wheel for it to work smoothly above 4k rpm. I have a 36-2 on the way, but i also got an ms3 for an insane deal, which i opted to just throw in and tune instead.

The speedy case has a custom 3d printed endcap that uses the stock mounting bracket to bolt up into the oem location. No zipties needed. will ship on buyers expense and trust. 79416
