Hi guys! Just found this radiator for sale on ebay. I am very interested but i wonder if its good. Anyone ever heard about GOLPHER ?

THANKS !!

 

I've never heard of that brand in the states. Construction and welds look a little crude. Especially at the inlet and outlet. Getting a proper fitment on any aftermarket radiator, even the better known ones, can be a difficult. The "30% better cooling" is an easy claim to make, but they don't even give the dimensions or capacity compared to stock. I don't know about the exchange rate or what shipping would be to you....but IMO it would have to be a VERY good deal for me to want to try it.

 

THanks for your comments Sgtblue! On second toughts, its better to buy one more expensive but reliable.

What radiators do you suggest is best ? Thanks again!

 

There are many good rads avaliable and you dont need to get water from china. I use a koyo and its working good for my aplication.

 

Not sure what ambient temps you have to deal with in Malta, but it really depends on what you do with the car. If just street-driven I think the stock size is adequate and there are all-aluminum alternatives that are less expensive than the enlarged versions...ala Fluidyne, Koyo, PWR etc. The larger ones also generally come with some fitment issues. This might get you started:

THanks again Sgtblue. The temps here are considered quite high and very humid especially during summer. Roughly, the lowest it can go is 11 degrees celius during winter and highest (max) of 42 degrees celius during summer. I only use the car twice a week but drive quite hard.

I am still looking around for various aftermarket radiators but apparently not all of them do fit directly instead of the stock one.

Thanks Busted7 for your help too!

 

There are other things to do for cooling before going to a larger radiator. If you haven't done so already, consider the FC thermoswtich (turns cooling fans on at a lower temperature) and the "Fan Mod", both are described in the Stickys. You can also get some upholstery foam and plug all the gaps around your radiator/AC condensor.
After that, I think I would just go with a high distilled water/coolant ratio, make sure my hoses were in good shape and get a good stock sized, all aluminum radiator (and AST). Should be fine.

 

Sgtblue, my problem is that the radiator cracked and need replacement. So i was considering an upgrade at the same time. I just saw this : http://cgi.ebay.com/ebaymotors/KOYO-...hippingPayment

What do you think? From the pictures the radiator seem to have a seperate opening for topping up. What's that??

 

That appears to be just a generic picture of a KOYO radiator for some unknown model.
The Koyo is 100% larger (thicker) than stock. As far as I can tell, everyone that has installed it has reported fitment issues of varying degrees...minor to major. If you have some ability and determination, it's a great alternative. Have you read through the thread I linked to, and the other threads that are linked on it?

 

Love the Koyo.

 

well sgtblue pretty much said everything that there was to say, but yea go with the known companies. i've heard good things about fluidyne.

 

Hi Sgtblue! Yes, i went through all the posts thanks to you. Apperantly, the TOYO is the best choice. However, i still wonder why other buyers still insisted that it fits perfectly. (Maybe there are various models). I contacted rx7store.com by e-mail a few days ago for a quote on FLUIDYNE but i didn't receive an answer. Yesterday, i tried Gotham racing too but till now, no answer too.

However, i received a reply from NYXRacing.com. Are they reliable?

Thanks again for all the help from all you guys!

 

With the problems Jason @ Rx7store has been having with his last Italian buyer maybe he is a little hesitant....

I bought the Fluidyne personally and I love it. I bought it because I didn't want fit issues but still wanted a top notch rad. I will admit that i had to trim the fan shroud a little to get it to align correctly with the rad, other than that the welds aren't Ron Davis quality but the price was right (I paid 420$). www.turboimport.com, great service and unbeatable prices on their "On Sale" items.

 

Thanks dradon03. I have just recieved an answer from Gotham racing. Koyo - $500 incl shipping to me.

Still searching for a cheaper deal......

 

Unless you have a real 'need' for a large radiator like the Koyo, just get a Fluidyne or PWR. The fit will be much better than the Koyo.

 

I'll guess that i'll go for the Koyo from Gotham. Its the cheapest and most reliable dealer i guess. Thanks to all !!

 

Doesn't RX7stores sell radiators? They are my source for all my parts!! Ever since I bought the car!

 

^ Yes, but unfortuantley they didn't answer to my e-mails.

 

Listen to a man with experience. Of course a 370-380$ rad is going to be cheaper than a 420-470$ rad. If you wanted the cheap of the cheap you would buy that Golfer made by Tiger Woods radiator.

The Koyo unless you are racing is too big. Fluidyne or PWR are the same dimensions. sales@turboimport.com or send a PM to "Jason" on this forum. I guarantee you you will have a response from one of them within 48 hours, is that too long to wait?
