Griffin for me. Used one before on my RB car was 10 degrees cooler running than the Koyo. I will use a Griffin on my VQ setup.

But my rebuttle is Kia offers damn near lifetime warranties on their cars, how many guys here own a KIA?

Just because you offer a lifetime warranty doesn't mean that you will get my or other peoples business, even if you pay for the radiator if I lose my job or I can return it no charge.

People have personal preferences, and sometimes stick to brand names they know.

I have a no name radiator in my car not ebay, not koyo, not mishmoto, not griffin, or lex whatever. Just a big motherfucking radiator that does the job and fits under my hood.

When it breaks, I will probably have a specialty radiator shop build me a radiator with a built in shroud and fans that mounts to my stock grounding locations so it doesn't bolt to my upper radiator support.

Which I can't currently buy from you, or koyo.

We all have different needs was my point.

Your first point and your second point both go i different directions. the first is like its implying "just get any it doesnt matter" but your second point goes at it in a different approach. and the way mishimoto responded is a valid response to your firsts post.

Here's some pictures as promised. This is an S14 Mishimoto radiator, S14 SR OEM fan shroud, and S13 fan clutch. The OEM AC fans was also mounted.

Absolutely no trimming was involved, although I did have to move the aluminum dryer canister for the AC a few inches up. Luckily there's already a threaded hole at that new position so the move was fairly painless.

I've been beating on this thing for over half a year now with this radiator and in the last couple months in the burning Texas heat with no problem so far.

I honestly don't think that the S13 SR radiator is any different to fit than mine. Please don't give me flak about how my cold pipe is touching the shroud, its a temporary solution.

^Thanks for posting up those pictures!

Mishimoto definitely has an amazing warranty, this will, in my opinion yield more customers going in their direction. Hopefully this warranty stays true for the life of the company because many bigger companies that have grow from their small business status' have neglected customer services and just worry about making money.

i would go with koyo.....my friend had problem with mitshimoto before...

Forgot to thank you for the pics. Mine fits just like yours except I have to do some trimming to get the hole on the top right to line up with the stock fan shroud but that's probably because of my car. Very happy with the rad so far.

:bigok: glad I can help.

I ran a Koyo on my s14 w/ s13 redtop-T28 and it always ran cool and nice, now I got a KA-T and Im in the market for one again, im gonna give mishimoto a shot...

SLiDe_WaYz 01-05-2012 06:09 AM

Get a Koyo, I had a mishimoto and had nothing but problems, yes they warrantied it but all 3 times it came with dents, holes, dings from shipping and leaked.

I'm using a ISIS now with there E fans and fan shroud now. Works great for me.

DallasTXjdm 01-05-2012 06:51 AM

I have a Koyo on my S14 and it works like a champ. No fitment or leak issues.

3411 01-13-2012 08:14 PM

just picked up a used koyo today looking foward to it didnt know a bout mishimotos policys tho its deff an option for my z32 now

Pinggg 01-14-2012 08:17 PM

koyo! end of story.

[email protected] 01-19-2012 08:33 AM

Both are solid pieces but customer service wins this one. Mishimoto!

str84dapokie 01-28-2012 10:13 PM

random addition... be sure to keep the receipt for the mishimoto rad cus they will not repair or replace under warranty unless you have it... i learned the hard way :(
i'm going with a koyo for my next one...
but the mishimoto held up good i guess (rb20 w/ 300hp)

i ran a koyo in my stock s14 with just water and it ran great

Jersthecool 01-29-2012 10:30 PM

Picked up a mishimoto from enjuku a couple weeks ago I'm gonna install it once my engine is back in but the build quality seems great. I've heard many good things about mishimoto and koyo so I just decided to get the cheaper option.

Initial_R90 06-11-2012 11:51 AM

I've had both on my LS1 s-13 the Spal fan ate my koyo and the M worked out fine

Is this still true today?

And you decided to bump 2 years old thread for that question?
You could have contact Mishimoto directly for that.

True. But at least he didn't make a new separate thread asking his question.

supersayianjim 04-02-2014 07:25 AM

so not speaking for an sr. but I had a z32tt and I ponied up the extra coin for a koyo for that car. and it did it's job. any a.im radiator is better than an oem copper unit.

I use cx racing radiators for my current cars.

-1jz sc400
-s13/rb25 swap

they keep temps consistently low excellent price and no leaks.

only thing you have to change is the drain-cock. other than that a solid purchase and a solid product!!

Nissan2nr22 12-08-2016 10:21 AM

Lets be real people, koyo.

itsjustdaphne 12-09-2016 08:06 PM

One time I had to last minute order a radiator for my daily and got an ebay one after I got a hole in the mishi. The ebay one, side by side, was the same exact unit. Literally everything looked identical.

feito 12-09-2016 08:55 PM

^wouldnt doubt it. Just like cheap coilovers: they're all the same, just different colors and names xD

supersayianjim 12-10-2016 06:31 AM

cx racing works just fine for me!!!

im sure it works fine for now but when you beat on a car you cant compare ebay products/welds and metal quality vs koyo quality, even wear and tear, i doubt youd recognize your cx racing in two years after pulling it out lol

ARC240 01-04-2017 01:54 PM

Without question, Koyo is the better rad out of the bunch imo. I've put Koyos in more cars than I can count, my own included, and have never had a single problem of any kind pertaining to quality, leaks or cooling on street or track. If I couldn't find the right Koyo aluminum to fit an application, I've used C&R (USA) and ARC (JP), all are top-quality products, fit and function incredibly well.

While it's true that anything will work, it depends on how well your application needs the radiator to work and how reliable it really needs to be.

RHD*bro 01-08-2017 09:27 PM

Koyo all the way u can't beat quality
