what would cool better?

What would cool better? a stock KA radiator with dual fans or a Koyo radiator with a 14" fan?

[spec-v5150]

I am a firm believer in 2 smaller of someting instead of one big thing (except breat bwahahahahahahahahaha..one big breast would be umm crazy to say the least)

I went with two 10" fans that pull 1100 cfm each. And i got em both for 80 shipped off ebay. I am leaning towards running them all the time. I dont know yet. I may get a thermostat just in case the temp thing on the DOHC cluster doesnt work with my swap. As far as the radiator....will the RB radiator not fit. It looks huge, but i havent taken measurements. After all that work to get it in my garage, i dont even wanna touch it today. Anyhow...if it doesnt work, i would go with a koyo I guess. Depends on how old your KA radiator is.

well I am running a brass KA with the single fan. Its daily driven in san diego traffic and no prob yet. But I still am getting the Koyo on Sat.

the r32 radiator fits nice in the s13.

[93RPS13]

anyone else??

[undertaker]

a R33 radiator is too tall. R32 GT-R radiator is a good option.

[93RPS13]

but it is for a Inline 6 2.0L

[undertaker]

but it is for a Inline 6 2.0L

the R32 GTR radiator is a nice bit of gear, it is made to cool an RB26.

but it is for a Inline 6 2.0L

and this would meen?

look at a s13 ka radiator it was for a 2.4 look at the r32 rb20 radiator it was made for a 2.0which is thicker?

[93RPS13]

my fault i wasnt thinking straight, dont read correct

[PROJECTRB240SX]

THE KA24E RADIATOR IS A THICKER BRASS TYPE FOR A LARGER DISPLACEMENT ENGINE.

THE RB20DET RADIATOR IS A STEEL-FIN PLASTIC END TANK THIN RADIATOR MADE FOR A 2.0L ENGINE.

IN THE END THE KOYO I FEEL IS THE BEST FOR A FEW REASONS:1) THICKER THAN RB20 RADIATOR2) ALUMINUM = LIGHTER AND BETTER HEAT DISP.2) NO PLASTIC END TANKS, NO BRASS CORE, BETTER BUILT TO HANDLE MORE POWER AND HEAT. WITH FANS YOU COULD GET THE RADIATOR TO PUSH ICE WATER FROM STEAM.

REMEMBER THESE ARE MY OWN PERSONAL OPINIONS. FOR WHATEVER ITS WORTH. OHH AND SPEC THE RADIATORS ARE THE SAME SIZE EXCEPT FOR THICKNESS.

[mmerritt2]

so which one would be good for the rb25? and where could I find one? thanks

[93RPS13]

just get a fan

[mmerritt2]

that helps........not!

[Joe]

look.the KA radiator will cool fine with 2 fans.

you dont NEED to upgrade the radiator unless you are having serious overheating problems or live in an extremley hot climbate (100 plus degree days)

[mmerritt2]

thanks for that info!!!

[93RPS13]

that helps........not!

.1 of displacment you mother fo smart azz, think about it cooling should suffient

[PROJECTRB240SX]

YES THE KA WILL COOL EFFICIENTLY, BUT I LIVE IN AZ SO I HAVE TO LOOK AT UPGRADING MY RADIATOR FOR THE KIND OF POWER I WANT TO PUT OUT, SO IT STAYS SAFE.

[93RPS13]

thanks for backing me up musicsurfman

[Nismo_Freak]

It depends on alot of different things actually. Your in a hot, dry climate for one. Your gonna be upping the boost pressure secondly. Now most people have issues here in Texas with the stock radiator when they run upped boost on the SRs. Alot of them switch to the 180SX and S13 radiators.

[PROJECTRB240SX]

NO PROBLEM IT'S THE TRUTH. AND YES IF YOU ARE REALLY WORRIED ABOUT IT A THERMOSTAT REGULATED FAN DOES WONDERS! LOOK INTO THEM AND YOU WILL BE AMAZED AT THE RESULTS.

[PROJECTRB240SX]

HE'S IN BOSTON, UMM HOW DO I EXPLAIN THIS? MUGGY COOLER WEATHER, SO HIS RADIATOR SHOULD SUFFICE, AS FOR ME I AM LOOKING AT THE ALUMINUM W/ DUAL FAN ALTERNATIVE FOR MY HIGH HEAT LOW HUMIDITY PROBLEM WHEN I AM LOOKING TO RUN UPWARDS OF 14PSI.
