Project Miatabusa Part 12: Why You Can't Make Aluminum Exhausts... And Why I Did It Anyway
by Dave Coleman
From exhaust port to tailpipe, project Miatabusa's exhaust system fabrication has stretched well over a year and has followed a circular evolution from brilliant hack job, to exotic race tech, and back to brilliant hack job. From custom-fabricated race header, to a lightweight aluminum tail section, to scavenged RX-8 silencers and hangers made from an S13 power steering cooler, the exhaust system is as awesomely eclectic as project Miatabusa itself.
Project Miatabusa Part 11:
Shorai Lithium Iron Battery (and Lots of Plumbing)
Shorai doesn't technically make any automotive batteries, but they have a full line of motorcycle batteries. I can't think of any reason why a motorcycle battery won't work in a car, and certainly not one powered by a motorcycle engine and charged by a motorcycle alternator. Shorai's direct replacement battery for the Hayabusa (theoretically all we would need to start a Hayabusa engine) weighs only 1.7 pounds!
Project Miatabusa, part 10:
Tubular Subframes and Engine Mounts, Oh My!
In July, 2010, we posted Part 2 of Project Miatabusa and proclaimed, in a very carefully worded headline, "the engine is in!" "In" was the operative word. Not "installed", or "mounted" or anything nearly as accomplished as that. In fact, we had kinda faked it, hacking away with a plasma cutter to see just what the engine wasn't going to get along with. Now, finally, the engine is actually mounted.
Project Miatabusa Part 9: We Finally Found a Starter!
Somewhere in the great wide world of starters, there's surely something that will fit in the notch between the Hayabusa engine case and transmission case, line up with the Miata flywheel, have the right tooth pitch for a Miata, and have an unshrouded pinion, right? Sure, but where?
Project Miatabusa Part 8: Miatabusa Gets the Shaft!
The idea was to take the Hayabusa's relatively fragile transmission and replace it with a shaft that holds a Miata flywheel. That's pretty simple to say, but actually doing it...
What are you waiting for? Holy crap, click on this thing!
Project Miatabusa Part 7 - Mounting the Gauges
Last time we looked at cramming the Hayabusa's instrument cluster into the Miata housing, it proved to be a shockingly good fit. There was a very large unresolved issue of how to actually secure the Hayabusa cluster's circuit board, though. Here's how that project was finished:
Project Miatabusa Part 6: The Wiring Job From Heck...
By Dave Coleman
Yea, well, it wasn't really the wiring job from Hell, but it was damn near the wiring job from Purgatory, considering how long it took me to get around to mostly finishing it. Surprisingly, nothing about the complete de-wiring of the Miata's engine control system and the integration of the Suzuki Hayabusa engine harness was really all that complicated.
Project Miatabusa Part 5 - De-powering the steering rack the right way
That's right; this installment of Project Miatabusa has nothing to do with putting the engine in the car. This may be the only Miatabusa strory where I don't mention the 11,000 rpm redline at least 3 times. Don't get used to it.

Nothing on Project Miatabusa is finished, but plenty is happening. Prepare yourself for a barrage of updates on our unfinished business.
