Default Radiator choices?

I am looking to get rid of the stock radiator to clear room for my IC. I was thinking about the honda half core one. I'm stuck between an ebay 3 core 3 Row Core Aluminum Radiator 12" Black Cooling Fan 92 00 Honda Civic EG Integra | eBay vs mishimoto duo core Mishimoto Aluminum Half Core Radiator 92 00 Civic D15 D16 B16 Honda Turbo Vtec | eBay

What's wrong with IC in front of radiator? Also what is the purpose of the car? Track? Auto-x?

Well for now it's just for preemptive measures for the motor. I was told at the last miata meet that an ideal ic/radiator combo would be to have them next to each other. That way neither of them are blocking air flow from each other.

For future reference I would like to be able to track it here and there.

The standard track tested method is IC in front. You have a lot more reading to do. This thread should answer what you need: https://www.miataturbo.net/race-prep...-thread-79930/

Long time someone did a side by side setup using a 3" core (from memory), it barely was good enough for the street.

Seriously? wow.. but how good are the half core radiator for a turbo miata? I would like it just for the fact that it will give me more space. Would it be better then the oem one that I have at least?

Doesnt matter, If you want a half core you'll need to do a custom setup so any rad of the correct size goes.

He literally just said that it barely worked for the street...

Is it due to the fact that it's a smaller radiator which holds less liquid?

Sorry I wasn't thinking straight my mind was to set on the space efficiency that a half core would give me. In other words.. no it would actually be worst for my turbo miata?

Half core radiators do not work in Miatas.

TNTUBA has one of the baddest miata's on here and runs a half core. One of the top cars in SSM auto-x. I'm pretty sure it can work if you do it right.

I'm not knocking Eric's car, because its well built, but being an auto-x car that only sees load for 60 seconds at a time for 3-8 runs a day, you can get away with a smaller cooling system.

I believe he has tracked the car. Maybe I'm wrong.

I believe solo I after nats was as close to tracking as its gotten. But some people have the opinion that prosolo is more demanding of the cooling system than tracking the car. Since you are ***** to the walls for 30-60 seconds, then sit in stop can go traffic for a couple minutes, and do it again. I'm not so sure. I personally have trouble keeping the auto-x car cool in weather over 85*F with the ebay manifold but it doesnt get hot until being back in grid for a couple minutes. IMO on a mazda B motor I wouldnt try running a half width rad on a track car, I just dont see it working.

Inaccurate statement is inaccurate.

Not only will they work. They will work well. You can talk about "autoX" all you want....but during a several hour long, steady state tuning session, it never even got got warm enough to have to take a break. If it's not going to get hot on the dyno....it's not going to get hot.

With two drivers at a the Pro Finale with a "pod" of only 4 pairs (read Hot Lapping) in weather over 100 degrees, the car never got over 206 degrees.

Is your half radiator an eBay special?

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.

No. It is a name brand 3 core. The car also has a hotside re-route.
