Anyone running an automatic radiator for extra cooling?
I just installed a turbo now the rad can't keep up.
I hot wired the fan and that helped.
Running waterwetter.
Installed belly pan for negative pressure effect.
Got 2nd fan coming.
Does anyone have experience running an automatic rad(2 row core instead on single)in a manual car?
I know a $500US race rad IS the cure but I can buy new automatic rad for $200CAN.
Any other suggestions?

Oh dear lord seach, then search again. All aluminum radiators can be had for less than $200 shipped, from godspeed, mishimoto, and one other I can't think of, cx racing I think, again, search. Your little '90 isn't the first turbo'd race miata, look up savington, hustler, my own, cueball1 (less hardcore) and a few others that I can't remember who track their turbo'd miatas fairly often.

new OE 92* thermostat
coolant temps hovers around 96* unless on boost or climing mountain then will run around 104*.The highest that I've let it go is 108*
thanks for the suggestions curly

Thread moved to General Miata.
OP: Yes, running the radiator from an automatic car has been done a quintillion times, though it's much less popular now that there are a bevy of inexpensive aluminium radiators available.
For what it's worth, are you overheating on the racetrack, or just driving around on the street? If the latter then something is quite wrong, especially given that it's probably not 40°C in Vancouver very often.

decent, I'm still overheating at the track with a coolant reroute, heater core reroute, and some minimal sealing around the radiator. They're not the best radiators by far, but they do work well, should be great for the street. I've done very little street driving with mine, but it's never over heated. And I'm generally trying pushing hard on the street to emulate as best I can track conditions, to test whatever system I'm modifying.

I've been reading this forum forever but never actually posted anything but now I have something useful to say so I'll say it!
I've never heard of image in motion (except for seeing them on the mishimoto site) but I've used CoolDirect twice before and both times I was really happy with the service! I got my parts (a radiator and a hose kit) pretty quickly, I didn't pay any shipping or pst, and I paid in Canadian $. Looks like they match prices now too although that must be new because I don't remember having that option... Anyway, that's my bit!

Powertoweight, automatic rads are very rarely thicker than manual radiators. When you're talking conventional radiators (copper/brass and plastic/aluminum), the only difference is the transmission oil cooler. The rest of the radiator including the core is usually identical. Anyway, thickness also isn't the only factor to consider when you need more cooling.
When you're talking racing radiators, very few of them are actually made for automatic cars. Most of the time, you need an external tranny oil cooler for that. If you're running a Turbo, the increased pressure will put a lot of stress on a conventional radiator and pushing it can blow a header, if your coolant gets too hot. You definitely should consider a racing radiator. Koyo makes some pretty mean radiators for the Miata but so does Mishimoto. They're a lot cheaper but they're really good rads. And as was said above, the warranty is pretty solid! Just thought I'd share...

There are sponsors on this forum that are Mishimoto dealers and sell them for that price.
I used to frequently overheat on the street, but I'm in Florida. Mishi is good. I love mine.
Support our sponsoring vendors. They are reputable.

I disagree. USPS is not cheaper, they just include brokerage in the cost of shipping. Since it's travelling longer shipping is already more expensive. The stronger CAD is still a 11% difference, plus fees to make the actual exchange. Then we pay duty (usually 6%) on anything not made in USA which is basically everything these days, we pay GST accross the board which is another 5%, and most province have a provincial sales tax on top of that. Then add the long shipping and customs delays, I think you have your answer.
Imagine $100 (we won't talk about shipping because it varies).
$100USD = $111CAD (if the exchange was free)
6% Duty = $117.66
5% GST = $123.54
7.5% PST =$132.80
So you see, it's 30% more expensive already and it's not even shipped yet. I've been buying car parts for years. When I have to, I bring them in from the US but when it's available in Canada, it's usually cheaper and much quicker. I realize sometimes it is STILL cheaper to purchase from the US and when it is, I do! Quite frankly, I envy you guys! You have it good!

As a Canadian,use USPS whenever possible.$5 brokerage free vs $50 plus for UPS.
I once ordered a wiring diagram book for $18 USD,forgot to ask for USPS,got sent UPS.Ended up costing over $80 CAN !!!!
ANYWAY back on topic
Just ordered from Cooldirect.They pricematched the other guys without any hesitation(less the shipping,which is free from Cooldirect)
That's $329.90CAN to my door,taxes and shipping in!
Let's see how long it takes to get it.
