My car is still months from being on the road. I did however bolt the fans to the radiator and the radiator to the car this morning, still have to wire them up but all the wiring will be done last.

I trimmed 1.5" off the top portion of the end tank and sunk the entire thing inside the radiator support. It was actually pretty simple to do. My aluminum welds aren't as good & pretty as the chinese




This may help if you are running intercooler pipes between the fans and the belts. 1.5" extra is a bunch

If you wanted to redo the inlet pipe, there's room to sink it completely within the rad. support. I may do this if I need the room.
Oh, I will add a filler neck/cap back in at some point.

Well, I FINALLY installed mine.

Lets start out with the bad:
I don't like the gap between the rad and the stock shrouds/fans. There's a good 1/4 inch between them. For most this is a non-issue and doesn't bother them, but for me it will bother me to no end. 2 possible solutions I see to it: cut down the aluminum mounts and thread them deaper in, then trim the sides of the stock shrouds, bringing everything closer together and "sealing up" the gap. or, put some shrouding/ducting/whateveryouwannacallit in the upper "gaps" to seal everything up.

Again, for most this wouldn't be an issue, but I just have to have everything flawless on thsi car or It will bother me.

If using aftermarket fans/shrouds this wouldn't be an issue either. I chose to stick with stock fans because 99% of the ones on ebay are garbage, and stock fans/shrouds will do a better job then them.

Otherwise it dropped right in (though it is a very tight fit, barely cleared the sway)

Took a TON more coolant, I think 2 full jugs of Prestone 50/50. Haven't flogged the car in heat yet, will report when I do, but I highly doubt I can ever get it to overheat, since it never even had any issues with the stock rad.

Update for anyone who cares:

This thing works flawlessly. I had a brain fart after installing some HID's and forgot to plug the fan back in. Then drove it for a week without a working fan, in 100* heat, and lots of stop and go traffic. Never even once got hot or had any issues.

Nice! I'm looking forward to seeing how mine works too! Are you using the ebay radiator cap or the factory?

I have to yank mine back out for the 18th time to redirect the lower outlet towards the side cause my intercooler pipe might be in the way, whenever I get around to doing the I/C pipe.

I know this thread is old and there are a few more recent ones, but I felt this one had the most useful information and deserved to be slightly zombiefied.

I recently took the plunge into "upgrading" my stock MSM radiator. It was overheating while being pushed. I could make Reverants warning light come on pretty easy pushing it hard up mountains. Lots of boost, not much air.

I ordered what I believe to be the same one as Vlad did because it was cheap and looked the same as the rest.

Dual Core Bolt on Racing 2 Row Aluminum Radiator JDM 98 05 Mazda Miata MX5 MX 5 | eBay

My stock radiator only has 18k miles on it.




Mounting tabs were cut, drilled and taped a little deeper to get fans closer to radiator.


This is what I did to space out the bolts instead of cutting them down or finding new ones.


I used foam like this on all 4 sides.


Installed.


Trimmed back of fans for intake.


Trimmed here too.



This does in fact cool better than the stock MSM radiator, both with decent ducting. On the same exact runs I was getting the temp warning light on my dash, I could not replicate while even pushing the engine even harder. And I have MSQ logs to prove it if anyone ever wants to see.

'Grats man

Yeah I actually still have to trim my fan mounting plates like that too. They're just mounted as it came. No issues though since the car is still n/a and comes nowhere near needing the amount of cooling this thing provides.

Is the AC fan really required? I don't have AC, and the normal fan is adequate in seriously hot ambient temps and stop n' go traffic. I feel you might be able to get away without it (especially with a bit of ducting or a slightly beefier fan).

Alright gayz (18psi, slmhofy, flounder). 17mo bump.

About to order: Dual Core Bolt on Racing 2 Row Aluminum Radiator JDM 98 05 Mazda Miata MX5 MX 5 | eBay

Anything that has changed since your initial reviews? Planning to run stock fans with a coolant re-route.

I might not be psychic... but I'm pretty sure what responses this will get...

1) If you're going to pay $419 for an ebay radiator, go a little bigger and get the Trakspeed or 949 radiator vs the ebay one.

2) If you want a fancy looking large aluminum radiator that may or may not cool better than stock, get a Koyo (or Mishimoto) for a lot less money.

3) Get the inexpensive ebay radiator.

4) Discover Emilio's "everything you need to know about cooling" thread, which I'm too lazy to link to right now.

I will say that I've been running the Mishimoto radiator for HPDE and Time Trials now for about a year... and haven't seen anything over 209 on the track.
On the other hand... I'm not drafting people. And the track days are up here in northern California. I'm sure things would be much different in W2W and 90-100 degree track days.

Your mileage may vary.

Take the time to read before commenting, and you'll notice the radiator I linked is the identical one that everyone I listed is using. It is listed a $419, OR BEST OFFER, so that people that don't bother to click the purchase history do not know what to base their offer off of. This entire thread is virtually based off of the radiator I listed.

Reading this thread it seems that most people were happy with it but i'm on a shared computer and don't want to risk logging into ebay to look at historic prices... What is the current "historic" purchase price?

I wouldn't pay more than $220 for one even with the positive reviews. I'd just pony up the money for the new one from 949 and know that I am supporting the community and getting a product that has someone standing behind it.

If you can indeed get one for $115 plus shipping then yes, sure. As long as the people who have one are happy with it, it is a no-brainer.

Last offer accepted was $119 shipped.

Yeah. When I saw the eBay listed price, I went "WOW!"

Update from me is that the radiator has worked great. I haven't been to any HPDEs so I'd say that my use this far has just been high hp street car.

That said, if I were in the market now, I'd probably save up a bit more and place a preorder for Emilio's SuperMiata Cross flow radiator and know I'm getting a really good part.

Haven't received it yet, but I bought this one for $140 shipped.

Cxracing Aluminum Radiator Mazda Miata 99 05 MT 2000 | eBay

They declined my offer of $120, so if you're so inclined, you could try $125 or $130.

I'll report back with any differences between mine and the ones posted here.

mine still works fine at what, 2-3 years later? can't complain.

I did have issues wtih the stupid mounting points and the stock fans, posted about it in my build thread, but nothing that can't be fixed in about an hour.

Please do. I may wait until you get yours in to help decide between the two.

Cool, I'll have to check your build thread and see how you chose to handle it. I've seen how a few others handled it using various methods like worming out the plastic whole and using a spacer to hold it down.

you can cut/drill/tap the mounts to bring the fans closer.
or you could just get the self adheisive foam and block all the gaps and seal the fans to the rad.

that's what I'd probably do now in hindsight
