Overview of the Supermiata Qmax reroute installation. Tips for purging air from the system bleeding. Some insight into why the reroute is needed on the B series engine in the MX5.
Looks like a lot of thought went into the kit. Thank you for your commitment to the Miata community! We always appreciate new gear to make our old cars run better ;)
Really glad to hear you spreading the word about cyl. 4 cooking most often. You guys make real nice stuff. I love this part you are showing today. $250 is reasonable for such a "neat" reroute. I learned a lot from you here. This setup will add miles to the life of the engine.
Just finished the install on my 1990, engine installed. The NA reveals some specific issues that were not address and any of the online materials found. A learned a few things that may be of help. First, I could not with confidence install without making as much room as possible. Removed the ignition coil, valve cover, and CAS (and few other small things). My 1/4" socket set with swivel head ratchet was very helpful. The lower and upper bolts are not reachable with a 3/8th drive. On the top back bolt there is not clearance for a 3/8" drive socket (maybe a thin wall). Second, discovered (the hard way) that installing the temp gage sensor would not allow the CAS to be installed. Was not expecting that, but reversed the order and all went in, but had to modified an old box wrench (did not have a crows foot) to get the sensor tight. As a racing application, this would go in easy with the engine out of the car. An in car install is a big challenge but possible with the correct tools. Third, and just a recommendation if you are going to make such a big effort to install this reroute, go to a hard water line to the radiator. It is worth the effort.
The amount of anxiety I got reading this 😅 I just got a new engine for my 1990 and this coolant re route so I am really hoping it all works smooth. I'm hoping my stock sensor works but we will see.
Badass video I bought the kit a few months ago and was redoing my clutch and other stuff getting ready for turbo and was feeling overwhelmed with how much I’ve torn my car apart. The coolant reroute is probably the first step I’ll take and I was worried about doing it. But after watching this video I am confident and now know how easy it’ll be f
Oh my god, it's so beautiful. You guys did a really good job of answering a lot of things that the other reroute kits didn't do quite so well. Glad I'm in the market for a reroute, but now I may have to swap this one out one my daily to my project.
Wish I had known I would have to do an EGR pipe delete because of this kit! *Update:* M8 x 1.25 pith x 25mm length button head cap screw (bolt) is the solution for the lower bolt. Will update if this fits.
Gorgeous kit. No mention of whether it can be run hotside or not? Also, I was really curious about your comment that the heater core line at the back of the head is an inlet. All coolant diagrams I've seen shows that coolant is pulled from the back of the head, into the heater core and fed into the waterpump joining with the cold water from the radiator. Is this not correct?
Same memory of every Mazda or 'other' diagram of any B-series engine coolant path. How coolant goes into the heater 'return' (Mazda's term) hard line from the Water Pump Manifold Inlet (normally a suction??) breaks all the rules I learned about fluid flow.
@14:13 - the mounting bolt that goes right there. How are you able to tighten that? There isn't enough clearance to get a standard wrench in there (opened OR boxed), and both the smaller socket and the larger 3/8th's doesn't fit for me. Thanks!
15:15 I sent you an email about the tapered threads. I was only able to get 1 turn in before I felt it was going to do damage if I went further. And the stock radiator seems to not be as far over towards the passenger side as yours.
I definitely need this! Do you think I will have trouble with bending the inlet hose around intercooler piping (FM) with a 50mm core rad? Product looks great btw.
We installed the reroute kit on our 2001 Mazda Miata with the engine in the car. Very nice kit, Highly recommend. Here is the video link. ruclips.net/video/zNOInNyuEV8/видео.html
But now Isn’t the problem reversed? Instead of cilinder 4 to be hotter the cilinder 1 will get the same issue? Because this system doesn’t allow the coolant to enter to the back and exit to the front. It’s the same as factory setting but reversed. So, what is the benefit?
Will my coolant reroute for my Miata require me to change out my head gasket? I thought I heard some where that my 2005 N/A Miata head gasket has covers for the holes in the block for coolant flow. Or should am I fine to just install my reroute and worry about that if I was pushing crazy power or something?
Any thoughts on installing this reroute while running a FFS Supercharger? I'm thinking I'll need to relocate my washer fluid bottle, and then I may be able to snake the upper rad hose through. I'm very interested in installing this kit, but worried about fitting that hose.
you have the water feed to the oil cooler capped off. where is the water heating the throttle body coming from? building a 1.8 turbo with mishimoto sandwich plate and ext oil cooler. or is there no water in the throttle body?
Hi I’ve got this coolant reroute with a pwr alloy radiator and spal 12” fan but I’m sitting at 96 degrees Celsius and the fan isn’t turning off, do you have any advice? It’s staying consistent but I don’t think it’s good that the fans have to stay on constantly
@@949RacingSuperMiata for my 2001 the heater hose conflicts with the EGR. I've ordered two of these and both housings are the non angled ones causing a conflict.

Right, seems like I'd want to use the block off plate with a fitting (remove goose-neck), run line from front of head to oil filter and then to the back of the head which you guys have shown as being blocked off in the car. I could run it 'back' to the mixing manifold where the heater core and radiator lines come in but then i'd just be dumping that heat back into the engine. Would also have to block off inlet on mixing manifold that is fed by the stock goose-neck t-fitting.
We do not offer group buys, sorry. Instead we offer parts that no one else offers at the lowest possible price. That is usually why things like this are so desirable :)

As a machinist looking at my coolant reroute you guys killed it this things bad ass great machine work and engineering for a reasonable price

I was wondering about a hard line for this bypass myself. Just picked up my first NA for street use and questioned the design of the cooling system.

Many options on companies for this but this video sold me on 949’s version. I will be buying this kit soon
I need this so badly, best reroute kit I've seen so far. Wish I had the money!
Magic Lisle Funnel is a must have for any work done with the coolant system.

planning on doing a reroute on my 99' nb, in need of these housings!
Cooool now i want a reroute
Great video. Impressive.
Great product and very informative video!
Are you able to install the kit without removing the crank angle sensor?
Yes. You can also download the full instructions from our website.
i'm getting one forsure.
Seeing the $25 dollar funnel set I bought for more off the tool truck... *punches air*

The Qmax restores the coolant flow path the B series engine (and all inline fours) had when designed.

Not a combination we have done ourselves. Good luck with your project.

That's an interesting question. We handle tech support via email or phone calls. Info@949racing.com
Can you use that plug under the super miata logo as a coolant feed on the Qmx?
will the coolant neck block-off plate (the larger one with the 2 holes in it) seal to the head? it seems to be a different size/profile
Kit comes with two plates, one for each option. For more details, download instructions from supermiata website.
thanks
Can I use this to delete the heater feed and return lines instead of looping them together?
Lupac Kid we provide excellent tech support by phone or email.
Is egr fitment effected ?
No

Where is the line for the factory oil cooler/heat exchanger?
Front block off plate, no change there. Go look at your car ;)
Right, seems like I'd want to use the block off plate with a fitting (remove goose-neck), run line from front of head to oil filter and then to the back of the head which you guys have shown as being blocked off in the car.

You have to move engine right
The engine does not need to be removed for installation of the Qmax reroute
Can you run it with the stock egr or will it have to be removed
You can, but the crossover tube is VERY close to the heater core house that goes to this reroute housing.
can you install this without removing the engine?
Of course. Visit our website for instructions.
Does it come in black?
Nope
@@949RacingSuperMiata I got you, Guess I'm going with FM reroute then.
