Default LFX Build Thread

Far enough along to start the build thread as I've had a couple PMs asking about progress.

1993 Miata. Keeping the shell, hardtop, shocks... not much else!

Gutted the car- nearly everything came out. LOTS of cleaning, painting, etc. In fact, only the gas tank remained- 180lbs+ of stuff not going back in the car (not including the seats, steel hood, pdf, exhaust..). I re-did the suspension: blast/ paint/ new bushings/ new bearings/ blueprinted hubs/ and installed Zerks. I've got a full brake package ready to install. V8R sent me the diff mount- it's installed and bolted up (Getrag G80 LSD with a 3.4 gear). The '12 Camaro LFX and 6spd is in the garage, as is a new alternator, computer, gas pedal and starter (eng came stripped). I've ordered new bolts from GM but it takes a MONTH to get the bolts. The engine mount kit, clutch kit, and fuel kits have been ordered and are in production. Also ordered the stage 2 rear end kit and aluminum driveshaft. I've got a fiberglass hood with integrated headlight covers inbound. I'm keeping the Boss Frog roll bar but will cage at some point in the future.

The car will mostly be a track toy and as such will have no radio, heat, AC, wipers, headlights... yada yada. But I'd like to be able to drive it on occasion, and want it to look finished- difference between built intentionally light and built cheap- so I am installing new carpeting and re-did the door panels with ABS and alcantara. Right now, I can pick up the car with my hands. The seat is a Sparco Pro 2000 carbon fiber with a PCI adjustable mount. I have a second mount and am searching for a passenger seat. Wheel is a suede Momo, wheels are 9' 6UL.

Still to buy: Clutch (replacing the OEM), hiring harness, safety harness, battery, Aim MXL dash, switches, brake line (-2an)... and I need to figure out how to run/ design the belt as I'd like to eliminate the power steering pump and ac pulleys. Wiring is another challenge...


I'm stuck now, waiting for parts. Will update this thread as the project continues.


As it sits now:







Diff Mount:



Has to be 1.5' up




Brakes/ control arms:









Door Panels:





Running Fatcat Bilsteins:

SUB'D!!!!! Been waiting for this one.

1 month wait for parts from GM. We're spoiled by Mazda. Parts support for Miatas is soooo good.

I put Hard Dog's bolt-in street cage into mine. Really nice for a track/HPDE/TT car.

Wow, off to a great start. I like the phrase "finished" lightweight build, that's the same road I'm venturing down. What did you paint the interior with?

Subbed for progress.

Lots of great builds popping up lately!

My buddy owns a paint shop and gave me a quart of something... Oil based, single stage. I sprayed it in the garage.
Yep, engine and trans came from s wrecked 12 Camaro $2500.

Excellent start. Love the attention to detail. Still in awe of the suspension bits. Looks great.

ECU_1 5B_RPM RPM
ECU_2 5B_SPEED Speed
ECU_3 5B_TPS Throttle position
ECU_4 5B_PPS Pedal position
ECU_5 5B_ECT Engine coolant temperature

ECU_9 5B_MAP Manifold air pressure
ECU_10 5B_OIL_P Oil pressure
ECU_11 5B_FUEL_P Fuel pressure
ECU_12 5B_IGN_VOLT Ignition voltage
ECU_13 5B_EGR_FB Engine gas recirculation voltage
ECU_14 5B_INJ_BANKA Injection pulse bank A
ECU_15 5B_INJ_BANKB Injection pulse bank B
ECU_16 5B_SPARK_ADV Spark advance

Your build is looking clean! What are the details about that upper A-arm ball joint? Looks like a good option instead of replacing the whole arm.

Is that a MOOG replacement balljoint?

That interior is sweet! The shorty console really helps.

Steel Hood??? Where do you get those?

Aftermarket replacement hoods are steel. Don't know of an aluminum source. That's one of the ways to check whether an older Miata has been hit . . . does it have a steel hood?

I am interested in this as well. So I was doing a little googling and found another thread where you asked about a tensioner bracket without the A/C and P/S. I would look at supercharger tensioners.

This looks like an V8, but the idea is still valid.
New Tensioner, Major help for belt slippage on 2300. - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums - Camaro5.com

It looks like the LFX superchargers are all centrifugal type and rely on the movement of the supercharger to tension. However, you may be able to get something together with the above company.

Thanks. I ended up leaving the ps pump and pulley. With a shorter belt everything still works without the ac compressor.
Got the frame rails, subframe and front suspension installed yesterday!

Looks good. From the one video of the V8R car at MRLS, I really like the way these sound.

Mine might sound a bit more aggressive than that one... no emissions stuff. I'm having Enthuza Car build the whole exhaust system.
