I was wonderine whic radiator is better it seems that Fluidyne is more expensive and easier to install and that Koyo is a lil thicker and is a lil more cooler.....so whats better overall? I dont really want a pain in the *** installin koyo if it isnt that much better can anyone gimme sum suggestions ? thanks guy (fitting, quality, performance, etc?)

 

Seems like you already know everything. Fluidyne fits right in, Koyo can be hard to install because it is thicker therefore can also cool better. I think some people have problems with certain fmic's with the Koyo. Koyo has a longer warranty. Personaly I would go with a Fluidyne.
Koyo's are all over eBay for like $368 if you want one.

 

is this something any Rotary shop dealer like, AIM Tuning can get?

 

I installed the Koyo and spent a little less for a little more cooling....if I had to do it again....I'd go with the Fluidyne..the things I had to do were not that big a deal, it's just that it required several trial fittings to find out where these problems were and what had to be done to solve the problem.

 

I agree with the post by member CantGoStraight about the "fitment" issues with the Koyo which require several trial fittings to find and resolve minor problems.

However, I also disagree with CantGoStraight in that I would go with the Koyo again because the fitment issues really aren't that big of a deal. You just have to be patient and it will take more time identifying where the Koyo is touching things like brackets or the A/C condenser and then do some bending and/or filing.

The Koyo is 2" thick and the Fluidyne is 1 1/2" thick. The Koyo's higher volume will result in higher cooling. I live with 100 degree summer weather so I always go with any extra cooling I can get.

The following link to Absolute Radiator shows the Koyo for $375 and the Fluidyne for $412.95.

Whichever one you choose, you are doing the right thing by upgrading from the stock radiator.

 

I read somewhere (maybe on the big list) that the core of the Fluidyne was redesigned or designed differently and cooled better even though it was a smaller unit. Can anyone confirm of deny this?

 

How about for front mount IC fitment?

I have the Koyo and I would have to say that it is a damn nice unit. Very well put together, even the endcaps are polished. Down side is as everyone says, gotta squeeze it in there. I mounted it and havent had time to reset it..so my cold air intake wont fit.(Intake box sits on radiator hose, now about 1" higher then it was) Im pretty sure that the SMIC M2 med wont fit either. But I looked at it and it seems that everything will fit just fine after a bit of tinkering. Looks really easy but I just havnt had the time. Would I get it again?...dunno, dont really have anything to compare it by. Just from what Ive seen though I think I would. Bigger is better....FL is one hot place you know.

 

Ok well all know that the koyo cools better, but the question is how much better and its it worth it for the issues you have with cramming it in there and certain aftermarket intercoolers not fitting in there properly. Ive had this question in my head for ages.

 

With the relative performance of the units hanging in uncertainty (though, surely both will be a lot better than stock), I think most buyers would be happier with the Fluidyne because of the relative ease with which it can be installed.

I have decided to go for maximum coolant capacity, knowing full well that the Koyo will be more difficult to install, especially with my M2 Medium IC. My car will be down for a while ayway, so I got a Koyo.

I have a MazdaComp radiator now, but I am looking for that last bit of cooling capacity after overheating the car under very extreme conditions. The MazdaComp radiator is nice, but I doubt if there will be many people buying these considering the lower cost options available now. I already have a list of potential buyers, so don't bother to email me.

I have the Koyo with the Greddy front mount IC. It is alittle tight but fits in nice.

 

I have a Fluidyne and am totally happy with it. The fitment is great, it was no problem to install. So far I haven't had any overheating problems, even after some hard driving on mountain roads. Is the Koyo the same dimensions as the Fluidyne, only thicker?
