A long time coming, but finally here! A few of you have picked up on our no longer available alternative. Well, this is why:
Why reroute?
The B series engine in the Miata was designed for a fwd car. As with all inline 4 cyl engines, coolant entered one one end of the head and exited the other end in the fwd application. This simple path is the most efficient way to extract heat from the head. Mazda turned the engine 90° and tucked it up against the firewall in the Miata. This meant moving the coolant exit to the front, the same end of the head as the inlet. This poor flow path is the primary cause for overheating which is so common in the 90-05 MX5. Our reroute has a carefully engineered low profile adapter for the back of the head to retain the original front to back coolant path. Just this one modification will significantly reduce coolant temps. Even a bone stock Miata will run a bit hot, and the stock ECU will reduce ignition timing which hurts power and fuel economy.
The Supermiata Qmax Reroute Features
Internally machined to maximize coolant velocity which is key to improving cooling efficiency.
Retain the use of your EGR pipe for emissions or CEL.
The OEM coolant temp sensor location is retained so the wiring harness does not need to be modified.
Spare 1/8 NPT ports are provided for aftermarket coolant temp or coolant pressure sensors.
All important hardware is stainless steel to increase service life.
High flow Stant Superstat is utilized to increase coolant velocity.
There's a non-orange prototype in my car, but you can't see it tucked up under the stock coils and crap.. We threw it on as part of the NASA WSC prep last year. So they have had some serious testing.
We'll get one mocked up on an engine out of a car for more beauty photos so you can see what it looks like put together.
We're also still finalizing the install guide.

Thanks. I have a decent idea of how it all works, I just want to actually see it to confirm what I think.
Love it all, except for the hose. It would be nice for the kit to come with a preformed hose like some of the ones recommended on this site for better fitment. Just my 0.02$; you improved everything else, why not make it perfect.
I wish IL motorsport would sell their silicone hose separately. But this QMax looks pretty good in terms of packaging, sensors, and that bleeder screw.

Two reasons for plain hose
- We have never found a need for formed hose
- Not everyone has the same hardware on the intake side. More than one way to route it
We went through many iterations in CAD before we started printing prototypes. Then several printed protos. Then several CNC alloy protos. Lots of tweaking. It's a nice as we can make it. You'll notice little details like stainless parts, name brand high flow thermostat, high quality reinforced hose. etc.
No cut corners.
The silicone hose in this kit is much nicer than the hacked-up Escalade hose that most DIYers use. Higher quality, more robust. If given the choice, I'll take the silicone every time.
I'll take your word for it then. My experience is with the M-Tuned reroute kit and I had clearance issues with the hose, most notably up front at the radiator inlet and idle air vacuum hose.

I think these issues are alleviated when using a crossflow radiator. The inlet is as far right as can be and not inline with the throttle body for an NA8 IAC to interfere.
There's no curly-Q coiled wire reinforcement required for this particular silicone pipe? I'm reading the instructions right now and the 1-2" of hose growth makes me wonder about the hose reinforcement. Seems like it would be possible for the hose to expand and kink.
The kit looks amazing. You'll very likely be getting more of my money.
19. To cold bleed system, open bleed valve. During filling from radiator, air will be forced out the bleeder valve. This is an important step to insure there are no air pockets in the rear of the system. Once the radiator is full, tighten the bleed valve.
