KA vs RB25det Radiator size

[240sxed]

I haven't done a swap yet, but im in the process and might just cop a motorset instead of a front clip. IM wondering how big is the KA radiator in comparrison to the RB one ? I've heard some people were having some overheating issues, but i live in San Francisco and it hardly ever gets hot here.

So basically my question is should i get a koyo radiator or do ya think the stock KA one would suffice and how is the size compared to the RB.

[dekand]

they are pretty much the same size, the rb is about an inch taller iirc , a lot of people use the ka radiator without problems so ive heard.

[BoostFab]

the core of the rb radiator is thicker.

Get good fans and you'll be fine depending on where you live.

I don't plan on buying any special radiator when I swap.. F that.

well i have a kayo radiator with my RB25 swap and i'm overheating, I live in Illinois so it's not to hot here anyway i had it looked at and my water pump is fine and my radiator has no leaks ( he did a vacume and preasure test on the coolant system) I have a 14 inch electric fan and a GReddy intercooler but I'm going to get the FAL dual fan and see if it helps!anyway as far looks the kayo radiator looks sweet with the swap!!

wow..that's odd, with a koyo radiator and still over heating.....might be some gasgate problem. You might install your fan the wrong way.

I use stock 240 radiator and one 14" fan infront of the radiator to blow to-ward the engine. I drove for 3 hours on hwy and it's fine.

no, my fan is facing the right way, i don't know what it is, the car runs fine, no smoke, or anything, next i'm going to have him do a compression test on the motor, i checked the oil and it's fine so i'm lost!...then again i don't know a whole lot about cars, just enough to get me buy

p.s...I had Mickinney do the swap so I'm pretty sure it was done right!!

don't forget if u hook up a pusher setup u need to reverse the polarity so it spins the opposite way(if it was originally supposed to be a puller)

Sometimes they got stock size koyo radiators..or stock replacements.

Im wondering, in SF it stays about 50-70 degrees all year around max and minimum pretty much during the day. Ya think i'll be ok?

i have stock KA with a fan that is always on and i have yet to have any problems.
