103K? 130K?

My wife's former 03 leaked between the core and plastic endtank at 30K! It was covered under warranty at the time.

So my vote is ... Koyo Racing Aluminum!

 

I have to ask, why all the "go Koyo" when koyo charges 40-50% more for a product that is no better than its competitors products?

 

Probably due to mishimoto originally having fitment issues and their filler caps? Those two would be the answer for me. Although fitment has been fixed.

 

I agree the cap is **** and you have to get a new one (oh no! another $10) but if there were fitment issues, they are fixed.

No reason to spend 50% more on a unit, thats money you can use for other things.

 

When larger radiators already cause issues small issues, additional fitment issues become a major turn off. Even if they're fixed, the reputation is still there. It takes a long time to break.

I believe CX Racing has had issues in the past with pinhole leaks.

I think Koyo has the name and a reputation of being one of the more good "budget" brands compared to other stuff like Fluidyne.

 

I have a koyo and its lasted me 4 summer seasons so far..Do it right the first time. Don't want your subby stranded on the side of the road.

 

Just replaced mine with a koyo but that was my only option besides running a lame at trans cooler.
The price you pay for insta-spool.

 

Honestly, I went with Koyo because they have a good rep for replacement stuff.
I'm sure most of the plastic tank radiators come out of the same slave labor factory in China.
The O'Reily's house brand is probably the same thing

 

True it is more expensive. But as I mentioned the fitment was fixed just like you did. The place I work at, we sell mishimotos to our customers we haven't had one fitment issue, miatas-evos. But we have hit two leaky ones with my boss' mazdaspeed all fixable but the nice thing mishimoto does have their warranty and they own up to it.

The cap portion only thing that sucks is, getting a replacement isn't instant unlike the koyo, you can probably find someone here with a stock one or the dealer if need be for a replacement asap.

I paid $200 with samcos for my 53mm koyo, pretty damn happy. Although I was going to buy a mishimoto through my work if that deal hadn't came up.

Fitment of a larger radiator is only required to trim the hoses a tiny bit, and allowing your aftermarket headers to melt your fan plastic

I dunno I would never buy an "eBay" brand just for the reason, I don't think they're flow tested. I definitely want something that flows rather than a piece of aluminum that cools my coolant. (In reference to CXracing)

True all factory replacements are koyo, hence I trust their technology.

 

I ended up with a Koyo and Koyo cap for my FXT. The build quality over the stock radiator is insane. The core is over 2x as thick.

My car with the stock cooling system had a near overheating problem at the track last June (in my car's defense, it was 117° and our cars get hot), but I replaced mine with Samco hoses and a Koyo Radiator, and since then despite having a few hot days, I've never come close to overheating.

Koyo will likely long outlast your car, but it's a good investment.

 

If you had the two products in your hands, it will answer your question. I once had a MR2 Mishimoto radiator and a 240sx Koyo radiator. The built quality of the Koyo was that much better. I would never recommend Mishimoto and this was when their stuff was dirt cheap. Now, it's even more expensive so No Mishimotor!!!

 

I dunno. I've been keeping a close eye out on how the welds were on the mishimotos we install and they're been looking pretty damn good.

 

Yea i ended up getting the mishimoto just cuz i didnt want to shell out more money. I have not had any issues at all with the mishimoto and like hide said the welds looked very good. Not issues at all so far :-)

 

The quality is more then just the looks of the welds, it's the overall construction. The mishimotor feels like a soda can compared to Koyo's tank. One way to make it cheaper is less material, which explains the weight.

The koyo for the 240 bolts on perfectly with every hole lining up. The mishimoto for the MR2 needs some grinding to fit the fan.

When a MR2 customer needs a radiator, I direct them towards a $400 Toyota radiator over a $250 mishimotor! Again, I haven't touch a mishimotor radiator in 4 years so their supplier may have changed!

On this S/C 300 with a 2JZGTE swap I'm doing ... Koyo!

 

I talked to a local shop who sells Koyo (Mann does not) and he said it won't last any longer than OEM, which realistically should be ~100K. They also said their shop sees just as many failures of OEM as Koyo. I actually could not get a Koyo when mine cracked and the car was already apart, so I went OEM with Samco hoses. The previous owner had replaced the radiator, but his mechanic was a tard and used some Chinese POS that lasted like a year apparently. Did the radiator on the WRX at 100K.

Mine is going in for A/C pulley replacement this week since it is squealing like a pig. A/C worked yesterday though.
