I have seen high horsepower evo's and hondas with these small radiators.

Could a turboII be cooled by it.?

micah

Evo's have small radiators? Perhaps more cores and less size? Maybe you are thinking of intercoolers?

I think he means a civic's stock rad. The one thats about as big as the TII's intercooler.

The answer?

No.

Is it the stock rad? I was under the impression that they were custom jobs that were designed so one could put the turbo next to the 1/2 size radiator core. All of the Hondas I've been around have a full width rad, except for my friend's turbo D.

But no, that won't even begin to cool a 7.

Besides, I think those half-width radiators are that way to they aren't exposed to the headers, since front wheel drive cars have their headers coming out front and down, and the engines are offset...

Don't even think about using one on an RX-7...

cpubugs

use one just to **** everyone off.. lol When it works fine they will all bow to you... When it fails we will all laugh at you.. lol Sorry couldn't resist.

The only Hondas I've seen with those half radiators are ones without AC. My friend's B18 Del Sol uses that little radiator with no AC. I can't say this is for sure correct, but I can't imagine why you'd want to use the little one anyways. It's not going to cool near as well as a full size radiator would.

Well I can tell you from working on Hondas. Most of them even with AC have the half radiators. I've put about 8 or 10 radiators in Hondas at work. But from what I understand a rotary would run way to hot for one of those little tiny radiators. Hell they are barely the size of an AC condenser.

No and no.. Wont even get close..

Sorry i havent responded till now.
J-rat, dude there are 600 hp evos with those radiators...
Because the turbo is too big and the rad was in the way. Same thing with hondas with big turbos.

SO wWHY NOT!?

The Griffin

I'm guessing because the turbo doesn't get in the way on the FC and people have enough trouble keeping the thing cool with the full size rads?

Ice_Wolf

Well, I'm guessing a lot of the reason is rotary engines run much hotter temps than a piston engine does. I can guarentee you there's no advantage to running a smaller radiator besides trying to save space, but why would you want to heat your engine up more? The radiator isn't an issue when fitting a larger turbo on a rotary because of the location of the manifolds. I could maybe see this being an issue on a 4 cylinder engine because most of the time, the exhaust is on the front side of the engine right next to the radiator.

I don't know whey you would want a Smaller Rad on a TII..the Damn engine Needs as much Cooling as Possible..You go right ahead and put your EVO rad in there.then When the Car comes to a Slammin Halt because it Locked up more solid than a Nun's Vagina,you will know Why the rad is That size,and Why Guys go To a KOYO or a Fluidyne..You are still thinking Piston,once you start Thinking Rotary you will know Why you can use half the stuff from a Piston Car.It's not meant to be!

Negative, unless it's a 5 row radiator....

Dcrasta

Only way to tell is to hook up one and get a water temp gauge and test test and test. Prove those who havent even tried it wrong or right.

deadRX7Conv

And, if one of those 1/2 radiators don't work, just use 2!

junito1

Maybe i didnt xplain my self as good as i should of.
Not a stock radiator. I am talking about all aluminum ,after market, 3 row, 3 inches thick, racing radiators, for hondas and evos with too big of a turbo.

Even the AMS 1000AWHP Evo uses one of these "half" radiators.

NOw would a 1000HP EVO make more heat than my slightly modded TII?

have fun with that...

I'll stick with my Koyo. I've already had enough heating issues this summer.

Nothing like making your cooling system high strung by putting in a smaller radiator.

The airflow characteristics of the FC make it impractical to run a radiator of that size. Use a proper sized radiator to maximize surface area exposure to the airflow.

you do realize that the stock radiator has trouble cooling a T2 once you start modding it?

1989_N/A

Dude, I have an unmodified N/A and I had cooling issues causing seals to blow with the stock radiator. I mean it was new, but it was OEM. So I would just suggest getting a regular Koyo or something and going that route.

But if your dead set on getting one, get it. Try it out and see how it works. There may be some ways of mounting it and using fans to help get it close to OEM cooling quality, but I dont think your ever gonna make one of those small radiators perform like a full size aftermarket one. But thats just me.

The combustion chamber in a rotary has a higher surface area to volume ratio than a piston engine. So the coolant must cool a larger area to keep the metal from melting. That means a lot more heat goes into the coolant compared to a piston engine. This is also a big part of the reason why rotaries get a little worse gas mileage than piston engines.

1989_N/A

On second thought, go ahead and get a "half" radiator and try it. If that doesnt work, get one of those gallon sized zip lock bags and see how that goes. lol.

haha..... Thanx for bashing my idea guys..

I just simply need more room in the engine bay. Better organized to make room for a semi-front mount intercooler.

I want to be able to get a aftermarket radiator to stand straight up and scoot back about 3 to 4 inches. The reason for this is to be able to put my intercooler in front of the radiator after it being stoond up and scoot back.

Anyone got any idea on what size universal radiator would be good for this set up? I still have stock battery location.
