Best radiator for under $550

[rhd_kyle]

Im about to get a blacktop sr20det, and i live in east texas. For those of you who do not know it get over 103 temp and its really humidity most of the time so i need a really good radiator.. Im going to be drifting the **** out of the sr20det. I do not wont to go cheap.. And i want the best radiator i can get.. I have try to seach and it is all koyo, and thats fine if that is the best.. Ok thats cool but i just want to make sure they are

im also going to put fans on the radiator is dual or single better? And what brand

to summarize:best raidiator $550 or under for east texas heat:fans dual or single and what brand:

[sr20goofus]

well i fyou want the best , get a thicker C&R Radiator and have it custom fitted to your car.

Koyo is fine, they work great, no one has problem with them, ever......

your best bet for cooling is to stick with a stock fan shroud and stock mechanical fan. you can get the dual electric fans if you want, but the stock style does a geat deal of cooling and i personally consider it to be more reliable, since you dont have to rely on a few wires to keep things cool.

Koyo $315 at heavythrottle, you could possible find it cheaper (ebay?)Pic is from FRsport, they are a sponsor here, but they are $399 right now

Checkout Greddy, 3 row core...you might want to add dual fans and fan controller, nismo thermo would be nice

Greddy is overated, considering the cost of Koyo and the fact that they are a radiator specialist, i think id go with the one that has more/better experience in rads.....Koyo is cheaper also.

I got my Genuine Koyo radiator on Ebay for under $300 shipped. Very good deal, stamped Koyo and they threw in a radiator cap for free.

As for fans, Go wit hthe early 90's Tarus fan. The 5.0L Mustang guys use those with no problems, will be fine for our little 2.0L engines. And get the SPAL fan controller from ebay for $70 shipped as well. The Fan new on ebay is around $70, I got mine at a junkyard for $40. The things pulls 2300cfm. I'm in Florida and this is the setup I'm running.

if you have a exstra hundred dollars i would go with this

http://www.240sxmotoring.com/cipsrcopa.html

its the koyo radiator the samco hoses wich if you ask come in diffrent colors and the flexlight twin fan wich i herd was really good

i know what you mean about keeping your car cool i used to live in arizona so this set up is top of the line **** and will keep your **** cool and it comes in a nifty package also if you tell them your a nioco member i beleve you get a nifty discount

^^^Good call...

Or you could sell lots of blood and get one of these...available in 2 sizes for the rich pricks...

There's a product price list at the ARC title page.

I bought an s14 fmic used for $500 CAN cause $1655 US is crazy!

to summarize:best raidiator $550 or under for east texas heat:fans dual or single and what brand:

-KOYO Radiator $289 shipped from Marty T from Injected Performance

- Altima fan dual assembly used from a junk yard is around From dealership it wouldn't be worth it ($300+) Ebay sells brand new aftermarket direct replacements for around $80

-Nismo Thermostat Either FRSport has a good price on this at about $65.

That leasves you at around $434

Another thing to get that will help with the cooling is getting a fan controller. You can get the Defi for a good price from FRSport with there discount on it. But I believe the HKS ($175) would be the better choice but would probably exceed your $550. Well goodluck and hope this helps.

Aluminum is just for looks, the 3" wide koyo al. radiator is still not as good as the .75" koyo copper radiator. With your extra money buy samco hoses.

LMAO at the guy who said the stock clutch fan is better than electric fans. Clutch fans go out also and when they do it sucks cause it makes your car slugish and puts strain on the water pump.

Dual FAL Fans that flow 2500 cfm will own any stock clutch fan. And they come with shrouds already around the fans.

Competitive Advantages of Copper/Brass Radiators(Versus Aluminum Radiators)

Technical

* High thermal conductivity * High corrosion resistance * High tensile yield strength * Higher melting point * Lower coefficient of thermal expansion * Higher modulus of elasticity * No-flux brazing * Easy repairability

Commercial

* Lower fabrication cost for tube and header material * Well-established recycling tradition (infrastructure in place) * High scrap value * Well-established aftermarket tradition (infrastructure in place) * High-quality reputation

Because copper/brass cools more efficiently than aluminum, a copper/brass radiator can be smaller to reduce weight and space. One new design with a "compact core" dubbed "Cu/Br II" has two rows of fins between tubes and thinner tube walls. The radiator is about 7 percent lighter and 15 percent smaller than an aluminum radiator of comparable cooling capacity.

The new brazing technology for joining the tubes uses a copper/nickel/tin/phosphorus alloy which provides a stronger connection and is more environmentally acceptable than soldering (which uses tin/lead solder). Brazing also means "solder bloom" (a type of corrosion that can form inside soldered copper/brass radiators) won't occur.

The inside and outside of the new brazed copper/brass radiator is electroplated to give it "unprecedented" corrosion resistance - which is an essential requirement for all radiators today. The radiator can also be easily repaired and recycled, the same as other copper/brass radiators (nearly all of which end up being recycled). Furthermore, the amount of energy needed to produce one ton of copper from copper ore is only about 40 percent of that needed to produce aluminum from its ore, so the overall energy picture for copper/brass is more favorable than that of aluminum.

Heres what it really comes down to:Core design, and not material (copper vs. aluminum). and adequate air-flow are the most important aspects for obtaining maximum coolant temperature drop from radiator inlet to outlet.

Do some reading before you make assumptions...http://www.koolance.com/techni....html

Alu absorbs heat better.Cu disapates heat better

One of the things copper is better than aluminum (radiators) is that its a green radiator meaning it can be recycled better. Like I have in the quote from some websites.* Lower fabrication cost for tube and header material* Well-established recycling tradition (infrastructure in place)* High scrap value* Well-established aftermarket tradition (infrastructure in place)* High-quality reputation http://www.copper.org/applicat....html

I've read both sides of the argument on different sites now and both seem to be just as good as each other

[Blown240sx]

The main draw back to copper is it tarnishes which lessens its effectiveness but tarnish can be removed.

Exactly. Thats why it comes to this like I mentioned earlier: Heres what it really comes down to:Core design, and not material (copper vs. aluminum). and adequate air-flow are the most important aspects for obtaining maximum coolant temperature drop from radiator inlet to outlet.

HEARD OF Haste radiator, check it out yourself. http://www.hasteusa.com. you be suprise, and they better than koyo and cheaper. RECOMMENDED! CLICK PRODUCT, THEN NISSAN

[Steve Lloyd]

that link says they are almost $150 more than Koyo..........and there have been a lot of recalls on those radiators.........

[CoupedUp]

You guys need to also take into account that the Koyo 3 Row Alum. may have more Rows of "cooling" but also the Koyo has 20 Fins Per Inch. While the Copper has 11-14 or something Fins Per Inch, I remember reading a Radiator Research article and it talked about how having too many FPI can reduce airflow and cause the air to go around the core instead. While a more free flowing one would cool better.

Now, I think coolant also has the same principles as oil, Meaning more oil in your "source" then more time for it cool off. Now does the Size and FPI differences off set each other? Maybe a little bit. I bet theyre both about the same in cooling efficiency. I would go with the Copper, A) its cheaper. B) More space to work with.

EDIT: As far as fans go, i would go with the Flex-A-Lite Dual. It molds perfectly to the Stock Radiator. I have the Altima fans and they dont flow as much as the FAL Duals do, not even close it seems. But The FALs are in a S13 with an RB25, so the motor is right on top of the fans so it may be forcing more air up as compared to my KA farther back allowing air through the engine bay. But those FALs make a mini wind storm in his engine bay. HA. Everyone says theyre loud and vibrate the car. I dont think so. Maybe other have them mounted wierd or wrong.

[partymonster 975]

koyos ur best bet.

[Emperor_Tha]

get koyo n-flow radiator, redline wetter water and used the stock fan since its always spinning.

[kane2g]

Griffin @ Summit.for $189 you get a radiator that works and been proven.
