See if you can get a USPS quote. I've shipped some fairly heavy PWC engine parts all over the world and never encountered anything like that.
It can't weigh much but the size of the box might be an issue for USPS. UPS and FedEx have very high international prices.

i asked seller for fitting fan, there is answer
"This is an aftermarket radiator,it may not be direct in,but it is one of the best aftermarket radiator in the market."
so this is not full plug and play radiator but core size is really close to stock.
stock has 335mm 640mm and this ebay radiator has 318mm 628mm. still i like it.

It's SMALLER than the stock radiator? I'd definitely pass unless your REALLY desperate. It's smaller and won't take the stock fan assembly, so it's absolutely NOT "the best aftermarket radiator in the market". He's selling you hard, but there has to be other sources. I can't see how your going to like it once it comes. I think you'll be sorry, probably like most of his other customers. But remember "all sales are final". 
What is wrong with the stock radiator in your car? If it's not in good shape, how much would a new stock radiator from MAZDA cost you?

its 52mm tick and stock is maybe 25mm... so its bigger. my radiator is fine but in summer and spirited driving is really hot. fans turn on quiet often. (in slow speed and after parking, so the temperature is over 105°C then fans turn on.)
main reasons for get a new one is fact.. its 17 years old, new bigger radiator helps cooling my car for sure.
iam still searching for better one. and waiting for answer (calculating postage for PWR)
thanks for your opinions

If this is a street car the stock radiator should be cooling your car sufficiently. A larger radiator doesn't necessarily mean it will cool better. The problem with the stocker is it's plastic end tanks, not its cooling ability.
Ducting is your friend, give air nowhere to go but through the rad, and make sure you use your undertray.
Look into a thermoswitch upgrade like the miata or FC to turn the fans on earlier, or PFC/Datalogit combo.
Unless you're racing the car I don't see a larger rad necessarily bringing your temps down.

iam searching through some sellers on ebay and collect information.,
this one for example:
http://cgi.ebay.com/ebaymotors/ws/eB...TQ:MOTORS:1123
"Our radiator is copied according to Koyo radiators,and some famous brand owner ordered the same radiators too,such as Blitz,Mishimoto etc.Since our radiators are aftermarket radiators,they are not the same as replacement radiators,you may need slight modify when you install.They come with the same plugs as the original radiators.The radiator can be returned in 7 working days."
this is really fair offer and nice postage for me its 85US.

I could be wrong but when an item on ebay says "you may need to slightly modify.." you might need a chainsaw, welder, sledgehammer and a machine shop standing by to get it in.
This forum (and many others) are filled with sad stories from people who bought "complete turbo systems $200 omg omg" "sleek headlights $200 omg omg"
Do yourself a favor and lay down the money for a well-made, well-respected, well-supported radiator manufacturer.
I don't know about everyone else but its irritating when you see complaints all the time from people who want to blame the car for some problem (damn rotarys, yadda yadda), and then you find out they installed a tin-foil china manifold or something.

I have read that it is the best fitting option and is a very good radiator which is why Mazda put their name on it. It's actually made by Ron Davis. Here is a site that sells them if you're interested....

Its a reliability mod, I dont think anyone is arguing how adequate the stock radiator works. The smart person who spends thousands of dollars on "modding",(in this case he has a single turbo etc) shouldnt be too worried about spending $300 on a radiator. Id sleep better at night knowing that my thousands of dollars put into the car aren't at risk of 17 year old plastic end tanks that could potentially crack and overheat my motor.

The PWR radiator that I bought off ebay came in this afternoon. I'm very happy with the construction and it's exactly what I expected, a brand new 55mm genuine PWR radiator. Not bad for $240 shipped. I don't think there is a better deal to be had right now. The guy still has 9 last time I checked. If anybody is looking for the link here it is.... http://cgi.ebay.com/ebaymotors/MAZDA...Q5fAccessories

Koyo + Greddy SMIC was perfect in my car.... fit like a champ.
Now i am changing to a FMIC and the Koyo still fits fine (just had to modify it to fit verticle)
just get the Koyo and an intercooler and call it a day.
What you could do is just get the RX7 store vmount setup which includes the intercooler and the radiator and everything to install it...
Done and Done.. especially if you have that huge turbo..

You definitely want to replace an aging stock rad, I experienced first hand a big florescent puddle of green in the driveway. When mine went, it went hard.
The reason I mentioned it is because if he's overheating, he's got additional issues other than just the rad.
