For every comment before and after this post questioning how well it works on the street..it doesn't. Sucks on the street and I don't care. I built it to hoon and fitted appropriate gearing. This is not a commuter :)
I probably wouldn't even think it sucks on the street. I drove my '90 NA with a light flywheel, stiff suspension and poly bushings from Dallas to Los Angeles at 90 mph most of the way, and frankly felt the sharp response from both the engine and chassis made the drive more relaxing than it would be in a pillowy cruiser.

FWIW, my 5/4.3 turns 4000 rpm somewhere near an indicated 80 mph. That's probably about 74 mph actual speed. Cranking along at 5000 rpm wouldn't bother me at all when the redline is 8500 or so.

Gave probably 60 rides in Taxi during the weekend at MRLS. Many grins. Here in the Corkscrew with national champion William Chen driving.

In car video from Laguna Seca

Incidentally, we have converted Taxi back to it's "coaching" spec for the Supermiata race series with a blueprinted stock motor. That means the 2.0L 200whp engine is available for sale. $8500 shipped to the lower 48 states. $750 for the complete TWM ITB system shipped.

Noises

So we pulled the motor out. Swapped the 13.5:1 JE's for ST 11.0:1's so we could run gas. Then swapped this transmission that sounds really funny.

This is the car that made me want a Miata. It's awesome to see continued development with it. Now I'm trying to decide if I want that engine!

Earlier this year we converted Taxi to a really funky setup to run in RoadsterCup Street class.

RoadsterCup rules: https://xsroadstercup.com/rules/

At the time it was set up as a ride along/coaching car for Supermiata. The intent was to replicate the P:W ratio of a SPM S2 car, but with a passenger. It had a VVT 2.0l, Megasquirt, Stoptech brakes, etc. We decided to configure it for Street class within RoadsterCup's rules, which is a fairly limited prep class, only allowing a handful of modification "points".

Off would come the brakes, ECU, VVT head, GV lip, AK spoiler, etc. These things all make the car marginally faster, but bump Taxi up a class or two.
On would go a simpler BP4W cylinder head, a adjustable fuel pressure regulator, adjustable timing wheel, and a crystal modded OEM ECU. All of which are "points free" in the RC rules.
We were able to spend those saved points on the best point per horsepower mod available: big cams.

It made 163whp/123wtq on CA91 pump gas.


We set it up like a PT car with stock swaybars, 1000/400lb Xidas, but with small/narrow 15x8 6ULs with 205 RE71R for less points.



Sonny drove it to a win at Chuckwalla Valley Raceway with a ridiculous 2:01.670.

With a lull in the schedule (other than SEMA and the 2017 Maxxis Supermiata Cup Finale happening on the same week leading into SLB) we decided to enter Super Lap Battle. SLB is Global Time Attack's signature year-end event at Buttonwillow CW13.
Global Time Attack rules: 2017 Rules

We decided to enter Taxi in Street class again. Much like RoadsterCup, GTA's "street" rules are pretty lax.
180+ treadwear tires, glovebox, carpet, and all OEM glass, are the only major limitations that prevent us from entering a racecar.
Carbon panels, 5" splitters, canards, power adders, etc are all fair game.

We are bringing a dull #2 pencil to a gun fight.

Prep will be "minimal", mostly stuff laying around or borrowed, including:
-Supermiata S1 front end: 4" splitter + vertical airdam, borrowed from Bullet.
-Singular Motorsports Aero Wing: APR GT250 wing specifically developed around the GTA Street class aero limits, borrowed as well.
-Swap out the crystal modded 5A ecu for a megasquirt.
-Skunk2 intake manifold, creating an opportunity to test on a much more capable engine package.
-Fujitsubo exhaust: major weight reduction from Racing Beat.
-245/40/15 BFG Rival S v1.5: leftovers from SCCA STR Autocross testing. Plan B tires include 225/45 SUR4G and the old 205 RE71R from RoadsterCup.

Hopefully we can get it to the dyno before the event.
Super Lap Battle is next Thursday and Friday, November 9-10th.
