I got the opportunity to review the http://www.mymizu.com/ Mizu Cooling Solutions radiator, cooling fans and silicone hoses. My car was running a Mishimoto radiator for the past 3 years, it is pretty much a knock off of the Koyo 36mm radiator. Old cooling system stripped out, ready for fun.

First thing I did when I got down to www.paladinlasvegas.com was unbox the Mizu and get the old radiator out to compare them side by side.

Not easy to see, but the Mishimoto measured out at 37mm while the Mizu measured out at 44mm, but what you can see is the upper and lower tanks are massive on the Mizu. Bigger tanks = more fluid, that added capacity is usually a good thing.

Time to slide it in place, this is where the fun begins. I've installed a couple 36mm Koyo's, the 54mm Koyo, obviously the Mishimoto and its always a fight with the lower AC condensor mounting points. First time, it went right in, also shocking because of the tank size. No cutting of the core support needed (unlike on the 54mm and 56mm cores radiators) and the upper mounting posts were actually in the proper location unlike my prior radiator.

Little tip to make things easier. On the passenger side remove the coolant reservior and the bracket before you slide the radiator in or out of the car. The the AC line bracket on the drivers side on the frame rail right behind the radiotor, unbolt it.

Next it is time to wire up the fans. This the the diagram that I8acobra came up with 4 years ago when we wired up istans car. Pretty crazy, I8acobra now works at Paladin Advanced, same shop we were doing my car at.

Fans are all wired up, FYI , when reading the schematic the color of wires is the chassis harness, not the wires after the cannon plugs that connect directly to the factory fans.

All wired and taped up, a pic from the top. Between the fan shroud and polished radiator, it is pretty. It is also very thin compaired to the stock shroud, very nice to have because of clearance problems on the FI cars. Then the show guys, this just adds some nice bling while pushing a lot more air that stock .

Another view, dam this thing is slim.

Hoses are the 2 piece set, upper and lower. Just like every other hose kit i have installed the upper hose needed some trimming to fit. The hose needs to be shortened roughtly 3/4 to fit without having a kink. Very simple to do, then i used a pocket torch to smooth the cut ends. They still look show quality when finished. Hoses installed and time to fill it up!!!

I really hate the bleeding process. First i tried the vacumm fill, all that did was create air pockets thru the entire cooling system. So I next broke out the spill free funnel

So nice to have, i bought one for home use. I still do a lot of the work out of the garage at my condo. While my car was running and waiting for the thermostat to open time to get some work done on the thmotorsports Circuit Battle Subaru STI

Back in the morning to finish this up. Not to mention, way to much to write up in one post. thmotorsports

 

Good write up mayne. I remember them asking for a member for them to try the setup out. Who better to try the setup than done one who tracks their car.

When viewing the picture I notice that the mizu radiator is shorter than the mishimoto one. I wonder if that makes up for the lack of length by adding width?

I'm curious to see how this setup holds up, especially with those fans because they look small. Do you by any chance know if the slim fans are only one speed like mishimoto's? It would be uber cool if they added connectors to the wiring to make for a plug and play process.

In for updates as to how much cooler and what temps your car gets after a few laps . I sometimes think about upgrading, because my whip runs pretty hot as it is. As for the funnel, its worth every penny.

 

Funny thing is that I was checking this Mizu radiator this morning on Ebay and was wondering why no one have installed it before.

 

Its only maybe a 1/4 inch shorter, the added width will make up for that 10 fold. When i installed the Mishimoto in the car a few years back i had to add just shy of a gallon, this install was 1.25 gallons so far. Neither time the block was drained.

Data, well I'm trying to put something together. What a pain it has been, ambient temp, road temp, with and without the AC on, what happens when the fan comes on etc etc. So many factors. My drive to the shop earlier it was 100 degrees out and coolant temp was 198 , drive home 110 ambient and coolant temp is up to 216 at 80mph on the freeway with the AC running. Turn off AC and it drops to 203 and dropping (ran out of exits before i had to get off)

More to come.

 

Awesome write up! Will those fans work with the larger Koto rad?

 

Yes they will, they will fit on any radiator that has stock style mounting plates. So you could even mount them to a stock radiator if you wanted.

 

Nice write up.

 

good stuff. seems pretty straight forward.

 

Good stuff man! Nice comparison!!!

 

cfm of fans?

i love THM Thanks again for the stance coil i bought a year ago

 

Cruise out to Willow Springs this weekend and meet them. Redline Time Attack/ Circuit Battles etc etc all this weekend. Mizu may also have a booth, i know i have met up with them at a couple of the races.

 

Is there one for the 07+ 350z models?

 

According to MIZU...will work on all 03-09 models with manual trans.

 

Terra, how are things holding up? I'm looking at picking up a new fan shroud since I'm going to have an intercooler blocking my rad. Would you use this over the Mishimoto?

 

Been working well, no problems with anything. I still havn't had a chance to get the car back out on the racetrack with it, sucks that will not happen to mid sept. For now, i am driving it to Texas, leaving on friday.

 

Nice write up on your new radiator Terra! I also like the price from thmotorsports!

 

I'm in Wichita Falls TX right now, its hotter than Vegas with high humidity. Looks like i'm going to break out the Cobb unit and start data logging out here. So far no problems, Dallas people will be able to see the setup next weekend at the autocross. I should be able to make it out to hang out.

 

Great write-up I just saw these and they install looks great.
