And my car is higher compression (read: more heat), higher boost (read: more heat) and higher power(you guessed it...more heat) than 99% of the cars on this site.
At the end of the day you need a well designed cooling system built with quality parts. What works on my car may or may not work on yours. your results may vary.

Obviously you're gonna get differing opinions on that.
One thing to look into is "water wetter" additive. I'm sure someone will crap on that idea too, but I've used it in the past with some success. Don't need it in my miata auto-x racecar. Running an oem radiator and a single high cfm fan and getting by fine.

**** me, dont be an idiot, stop.
Side by sides can of course be done, all sorts of **** can be done if you are clever enough to design and test a system that actually works using the right components.
But for **** sakes OP, just put a reroute and a cheap ebay radiator in and stop with this BS.

Hopefully OP doesn't mind me "piggybacking" his thread since it could help him and others. So my brown/green oem ticking time bomb of a radiator has finally decided to "blow" or rather seep from a small crack in my case. I had planned on getting a SuperMiata crossflow radiator($350) when they get another batch in since they usually sell before/by the time they get stocked but obviously I can't wait so I wanted to get experience from other Miata owners with the options I provide or others but please provide the information in the following format to make it easy to identity details:
Year of Miata:
Aspiration w/ list of engine modifications:
Primary use:
Brand of radiator:
Mileage/length of time since installed:
Comments:
Here are the options other than the SuperMiata crossflow($350, that isn't in stock):
$525- Flyin Miata crossflow 32mm core
Flyin' Miata : Engine/Drivetrain : Cooling : FM crossflow radiator
$279- Koyo 37mm core
Miata KOYO Radiator 37mm V1139 ALL Aluminum for Miata 1990-1997
$259- CSF 42mm core
CSF Miata 42mm Two Row Radiator for Miata 1990-1997
$255- Mishimoto 52mm core
Miata Mishimoto Radiator for Miata 1990-1997
$165- Sonic Motor 57mm core
Sonic Motor Aluminum Radiators - Sonic Motor - Power and Performance
You may ask why I didn't include the Track Speed Engineering crossflow radiator...well because it is overkill for my application/use and I'm not willing to slap down six Benjamin's for it, great as it might be.
Now I will be using mine, stock '97, as a daily in the normally warm to hot Texas days and hope to have it turbocharged by this summer. I also plan on doing a coolant reroute with the radiator replacement or before the turbo install. I appreciate everyone's assistance with this!

FYI: I have done research on the subject and found a good deal of helpful information, especially in the cooling thread on here, but was hoping to get a collective of responses to aid myself and others. My apologies if I missed such a thread.

Year of Miata:94 Miata, 97 miata
Aspiration w/ list of engine modifications: 94(Begi S1, 10PSI, No AC, Begi racer reroute), 97(MKturbo setup, AC/PS, no reroutes of any kind)
Primary use: Street and Autox
Brand of radiator: Original ebay radiators from 2008 mt.net group buy
Mileage/length of time since installed: 4 years before it started leaking on original one. Other 2 have been great for years.
Comments: I am a huge fan of the cheapest all aluminum ebay radiators you can fine as long as you are not doing heavy track days. I currently have 2 installed in 2 of my miatas. They work great and have decent fitment for the cost. The only way I would spend more money then that is going to a 949 or TSE radiator.

CXRacing is good for the cheapest non-plastic option, but while their customer service is OK, their quality control is poor at best.
Out of all your posted options Chad, I'd go this route:
Same manufacturer as the 949 one *very high quality*, same B-tube fin tech, with a more conventional configuration and a $100 lower price tag. If you can't wait for the next batch of 949's, this would be my choice.

Chad if you werent having heat issues with the stock radiator put another stocker in. It'll last another 20 years before breaking. Things might change once you go turbo, if you go turbo, but since the radiator you want cant be had right now then $50 or so might make sense.
I really appreciate everyones quick responses and not brow beating me for continuing with a subject that probably gets beat to death!

Aspiration w/ list of engine modifications: FMII stroker (GT3071R)
Primary use: Street; Autocross; Track (HPDE)
Brand of radiator: FM Crossflow rad
Mileage/length of time since installed: 20,000 km; 2-3 years
Comments: I can finally run a 20-30 minute track session without getting hot (or tackle a mountain pass with A/C running). It took the following:

Comments: I can finally run a 20-30 minute track session without getting hot (or tackle a mountain pass with A/C running). It took the following:
- FM Crossflow radiator
- M-Tuned coolant re-route
- FM airflow kit
- FM oil cooler
- 20/80 coolant/water ratio
- Ducting that forced all incoming air to go through the heat exchangers
- Probably some other stuff that I can't recall right now

I run a large oil cooler mounted in front of the radiator and the radiator is boxed in on all sides to half of the front mouth. I haven't driven it in the street but it would be fine as it ran on the dyno for hours without any issues. I also have a hot side reroute and no thermostat.
Having said all that... why bother with a half width unless you have serious plans for the other half? I had to make custom hangers to support the radiator and oil cooler. You can get the cheap ASI full width bolt in for not much more.
