i saw these radiators on rx7store.net and even though they are the cheapest radiators they have, they look pretty good. what particularly intersts me is the one year "no-questions asked" warranty.

i checked out they're official page and they seem pretty established for only being around since 2003.

my end tanks just blew on my stock radiators and i need a decent upgrade and i'm always shopping around (of course).

i just wanted to see if anyone had anything to say about these.

 

get koyo or fluidyne

never heard of mishimoto. Then again, you never know. You should try it out and let me know.

 

i never heard of them either and they were just added to the stores product line

i might call jason and ask him about them

 

Those radiators sold on ebay. There are threads concerning people using them. try a search.

 

gahh! ran a seaarch myself. nothing. must have been thinking of haste/godspeed rads.

 

 

even with the one year "no-questions asked" warranty?

i'm pretty sure i could make it break if i really wanted to get a new one

 

What are you going to do after 1 year?

 

no questions asked warranty= awsome, but that doesnt help your coolant seals if the engine is super hot and toasts itself after your rad blows.

 

^ good point but i have a good WT gauge so i'm not too worried about that, i'd keep it under wraps


break it before it hits one year...only be able to get away with that like....twice

 

More importantly, why are they selling e-bay items. I know the generic downpipes they sell are trash, the flanges are no good and the piping is paper thin

 

if it breaks once, it's definitely going to break on you again and you'd probably end up buying another one. Why not just go ahead and get a good reputable one straight from the start?

 

Well, for our cars (entirely depending on how you drive them) cooling is a pretty serious concern. Personally that is one area where i would not skimp. I have a koyo n flow. I have koyo radiators in all my cars actually. Basically dont let the warranty fool you, a good quality radiator should not have any problems after many years of use. If you have a problem within one year you may be in a bad situation. Not to mention i dont like working on my car all of the time...only most of the time.

I have the largest version they sell since my car is being built for track duty:

Don't get it just because it's big as you'll be very unhappy (as it requires some modifications to fit). Get the standard aluminum OEM replacement or the middle size one which would be similar to a PWR or Fluidyne size.

 

If you really value your car, I wouldnt take a chance with the mishis. If theres one part you cant skimp out on its the rad.

 

+1

those i know have worked out well for our cars.

 

Well I guess i am the only one that is running this in my car. I am getting my car rebuild at AZRR and they are doing everything. they told me I should run a Mishimoto or a mazda speed radiator. They to me that i will get a better air flow from them because they are thinner compared to the koyo. I really dont know much about these radiators but the guy at azrr has worked with paul yaw and helps mazda with research and development.

 

If it has a good fin count and is multi-louvered it will be fine. Just because it's cheaper doesn't make it any less effective.

+1 on radiatorworld.com standard aluminum multi-louvered replacement.

When you buy any aftermarket radiator I'd inspect it for clear inlets and outlets, etc.

 

Mishimoto is pretty new to the market. Its actually a nice radiator for the price and works well.

 

just spend a little more and buy a rad that you know will work. these engines arent cheap, and even with a wt gauge if the rad breaks and spits all the coolant out, it only takes a second to overheat and all it takes is one time.

 

I have a mishimoto radiator, haha... wow one of the first ones here? I actually have had it for 3 year plus, and it's still working well. First off it's on my civic. I hit a bag of cement (on street adjacent to home depot) and it cracked my original rad. I had picked up one of these because I was pretty limited in the cash dept at the time and I needed a rad to make my car move. I picked up one on ebay, for the price of a stock one (non oem) hoping it would last me at least a little while. 3 years later and multiple track days later no leaks.
honestly I had limited hopes for the rad.
for me, The welds were excellent, even around all edges, evenly spaced, the rad was also pretty thick, but install went pretty well.
Only thing is that it doesn't accept the stock rad cap, they supply one with a mishi sticker over the info part (sucks assuming you want to see the spec on the cap)...ohh the nub that attaches to the overflow tank is tapped into place and sealed, not one piece with the filler neck, other than that, no real problems.
I tried to be as objective as possible, let me know if i can help, i can't comment on performance, because I had a single half sized rad before and custom mounted the double width (because of h22 and all). i don't have a digital temp guage but I have never had trouble with temps.

 

^ finally someone with real input

either way, when the times comes i think i'm just going to get the whole v-mount setup from rx7store because i like the way the IC is mounted and takes up the whole front of the engine bay and there is no need for sided ducting from what i have seen

 

I just installed one on my friends FD. No complaints originally looking at it. But the fitment is pretty bad. The fans don't line up very well to it and the fan shroud will not seal against it. There is no nipple for the AST, and if my memory is correct, there isn't even a drain. The pegs that sit in the stock rubber bushings to support the bottom of the radiator were off by at least 1/2". There didn't seem to be anything to support the top of the radiator, so we left off with it just sitting in the engine bay.

 

i was looking at one of those but i think ill be going for the koyo now or the one on

after what "tt7hvn" said about them

 

Do you know what kind of modifications needed to be done for their track duty rad?
