Hi all you fantastic Miata people.

looking at re-route options, I’m based in Australia and FM is a possibility but wanted to voice my thoughts and hear what you you guys and gals think.

The Qmax is also an option but FM is cheaper here and the stant thermostat isn’t as easy to grab as the off the shelf one in the FM.

I kind of like the idea that with the FM one the hotter water from the charger returns to the radiator rather than back to the motor.
What I really don’t like is the reduced flow to the charger that is mentioned in FM’s description.

I have read about thermal syphoning and as a side note I was interested that Garret recommended a 20 degree angle on the core to promote extra flow, sorry I digress.

Regardless of what has been said I still think that more water cooling has to be better than less for the oil being cooked passing through the turbo.

My thought is use the current water feed that most of us use to the charger but instead of having the water return to the mixing manifold have it go to the FM re-route housing and back to the radiator, in theory it’s not using the small feed from the FM reroute when running and with the elevation difference should help promote flow with thermal syphoning after shut down.
Let me know what you think.

Thanks in advance for your replies.

Curious about the price difference considering you're in Australia. Standard Qma price seems to be $60 less, currently on sale for $90 less.

Regarding the turbo feed, Qmax has auxiliary feeds on front plate and rear housing. We don't offer a PnP tubing solution for turbos but the user can configure anyway they like using the auxiliary ports provided in the Qmax.

The 45848 (180°) and 45849 (195°) thermostats we use are widely available and nearly as common as the OEM thermostat. They also tend not to fail in the first place.

Thanks so much for your reply Emilio,
I really really appreciate it, as I know you are busy.

Please don’t get me wrong I really like your kit as it’s been around for some time and is race proven and if it can keep your race cars happy I know it will work on mine.
The price difference was in the shipping FM is $22.65 and Supermiata $106.41, which surprised me in the difference. Would you like me to contact you through your business to confirm the price?
because if it is incorrect I would love to purchase off you.

The turbo lines aren’t really an issue just was a point of difference, a difference perhaps not needed?.
again your kit has been proven for years to work and work well so not a major issue.

As for the thermostats I can walk in and grab a Miata one at any part store here however Stant isn’t a common brand here but with those numbers I’m sure I can find a cross reference, can you supply the kit with a 180 or a 195 thermostat?

Thanks again for taking the time to reply.

If you're installing the coolant block with the engine still in the car, I'd recommend the QMax option.
It's still a pain in the **** to install but the QMax option is simpler than the FM solution and there's very little room back there..
Make sure to thoroughly clean off the original gasket and use the sealant provided in the QMax kit - I tried a gasket and it leaked so re-installed it with the sealant instead.
