I've owned this fun little car for 15 years or so and it went from my commuter car (in the summer/fall) to a weekend car to a full time project car.
It's been garaged in a climate controlled garage the whole time I've had it. For the last 5 years it's been sitting in my garage with the motor out, waiting for a rebuild (coincidentally, I have a 6 year old daughter). I finally got some time to spend on it and got it rebuilt last month, pretty much so I can sell it and make room in the garage for my wife's car (and maybe a motorcycle, again). It has 160 miles on it so far and will be going up slowly as I break it in.
With the stock motor I was running 25lbs of boost without issue (aside from traction issues) but I also only drove it about 1500 miles a year.
The chassis has right around 136k miles on it.
It has a new'ish soft top with a glass rear window and a hard top (with defrost).
New tires and wheels.
Miata LSD with 4.10 gear.
Original 5 speed transmission but the seals and bearings have been replaced.
Flying Miata frame rail braces.
Now for the huge list of everything around the engine:
AEM standalone ECU
AEM Wideband O2 sensor/gauge
AEM C2DI with Coil on Plug ignition
Rx7 fuel injectors (reconditioned/cleaned by Marren fuel injection)
255lph Walbro fuel pump
original head with mild port and polish, surfaced, all new Supertech valves and valve gear (including springs)
all new lifters (hydraulic lash adjuster if you prefer)
original block bored .20 over with Manley rods and Topline pistons
ARP head studs
all bearings (rod, main and thrust) are ACL race bearings
2001 Miata oil pan and MBSP
coolant re-route (my own version but similar to what most people do)
BEGI coated manifold
t3/to4e turbocharger (very large journal bearing turbo, .63 hot side but I'll have to check and update this)
Dual port external waste gate with electronic boost control by the AEM ECU
3" exhaust from the turbo back
reasonably large intercooler (i probably could have left the AC exchanger in place, but I didn't)
Many more things, i have a stack of receipts for machine work, parts, ... I should have measured the intercooler and wrote down the turbo specs but I'm at work and had a moment of bravery to actually post the add. I'll update that info later though.
I live in Virginia, in a county that does not require emissions inspection but i did put a cat in the exhaust (highflow 3"), I don't know if it would pass a state sniffer test but to me it seems to clean up the exhaust enough that nobody would wonder if you had a catalyst or not.
The car originally had AC but I wanted the extra room for a better intercooler fit. I kept all the AC parts if you want them.
This car does NOT have power steering (I really prefer not having it on this car, even with larger tires).
Actually, I found a thread I started on here a long time ago with a lot of details:
