Got a salvage motor a few weeks ago and have a full rebuild kit on order. The block is going to the machine shop for deck and bore, head will get a valve job and new seals. This is a rebuild to spec, not counting whatever overbore is required. Spec motor is good for 250. At 270, rods start popping out of the block. My goal is 225whp, which would be 125% more than I have now. I'll get there with an mp62 supercharger, an AEM EMU, upgraded fuel system and intercooler.

Very nice. I had an AEM standalone in the Integra I had a while back. Its an excellent piece of equipment and extremely user friendly. I had zero tuning experience when i got it and in a matter of a couple months it went from not starting at all to burning the front tires well into 2nd gear. That was NA though... not sure I'd be so brazen with a boosted motor...

What kind of 1/4mi time will a 225whp Miata do?

That looks so nice, & that thing must go boom. Any rattles?

Maybe a couple lil rattles. It is a 1995 after all. But I have put down dynamat in the trunk, parcel shelf and behind the door panels. After doing the same for the FX I couldn't stop from doing it to the Miata.

Compared to the FX the Miata was super easy - about a quarter of the real estate. If I am ever working in a new part of the car I take the time to make sure all the harnesses are secure and not exposed to the elements.

I meant to find out about the 1/4 time but it's been a while so I forgot. If I don't hear before my build is done... I'll let you know after I go to the track.

This past weekend I swapped out the headlight assemblies for a low profile kit. The pop-up headlights open only half as far as before and the light output of these lamps is better than the OEM "bug eyes".

Old & retro

Low profile & more inline with the style mods of the car, IMHO.

Just installed the center console bezel, wrapped in leather matching the gauge hood, upper door panel, door handle & shift boots.

Exactly. This is a close approximation to a dry shot, but not really. The stock ECU does compensate a little (shown by o2 sensor) with the fuel injectors but not enough for reliability. To safe the motor we could retard the timing but that would be a base timing change and not ideal for any rpm without nitrous. I would expect the motor to pop after "a few" pulls like this. With that AEM on my radar screen, i could address getting the AFRs into a safe range. But that would be only after the supercharger kit.
 
Might have missed it, but do you have an air flow controller? You could preset a few programs to accommodate with nitrous and without. Would be able to do on he fly.

No - the video shows a guy holding the nitrous bottle and aiming it at the intake. I don't have any type of system installed on the car. Interested in what you said - an airflow controller? Not sure I've seen this before - any cars that use it standard?
 
Yeah, an AFC. Some mistake it for air fuel controller. Used heavily on boosted cars to adjust the air fuel mix. You essentially interrupt the signal and dial in less or more air in the mix to accommodate for running rich or lean. I've seen people lean out bolt on cars this way to gain a little cheap power, but it's best on boosted or NO2 cars. Careful though, the leaner the more power, but also closer to detonation. And egr or wideband is a must.

This tech might have been integrated to stand alone systems in today's world. This was a standalone when I played with turbocharged and NO2 cars a decade ago.

That makes more sense to me. A standalone would definitely give me the ability to control any type of boost; mechanical or chemical. The 95 Miata has an EGR - did you mean EGT sensor?

I plan to delete EGR (Exhaust Gas Regulation) which is used to lower the oxygen content of the intake charge to prevent detonation. Without that safety measure, tuning the AFR will be entirely based on the wideband O2 and a standalone EMS (AEM). At that point I would expect to be able to handle a higher fidelity NOS system - wet shot direct port; the safest in terms of being able to control output for each cylinder. On top of that would be window and limit controls - aimed at keeping the torque under control. But that's a whole other project. First, we must bow to the MP62.

Off the shelf, this kit is capable of 175whp, but this is with a low fidelity timing & fuel control device. They claim stock like driveability and there plenty of thrilled customers out there.

This is a kit developed enough that it is a DIY install. I won't need to go to my shop until it is time to add in an intercooler and the AEM EMS. After those additions, 225whp is a matter of tuning.
 
This thing is SEXY! Minus the wire mesh on the bumper.

Whats a normal miata going for down there? I've always wanted one but never found a non-rust bucket at a decent price around IL.
