guys our car with is middel east the radiator size is 28mm cause in our countery the temp reach 48C so if you buy the our OEM radiator will be best for you cause it is stock for you

 

That's a good option if the non-North American radiator can be purchased from Nissan. I believe JDM Z's get this two core factory radiator as well.

 

i'll have to measure the size of the rad down here in aus. i suspect same as the american market though.

 

Your thinking of PE. They run water cooled turbos but dont connect the water lines.

APS run water cooled turbos and connect the lines to your existing coolant system.

 

I read if I remember correctly you have a dual core in AU. As the JDM and EAU
cars have. It would appear only the USDM and Euro car's have the single core.

As far as Koyo's go, a dual core can be fitted with a minor trim of the mount. Very little cussing.
However when the same craftsman installed a three core the cussing and grinding was noteable. ( Hi Tony ! )

Cheers Amy

P.S. Sharif with his mod used a two core Koyo and was very succesful.
Wld350Z's two core stock install has some heat soaks and temp spikes, if I recall.... But we have had an extremely hot summer in So Cal. ( Greddy TT and E-Manage Ultima and 650 CC injectors ) This was before the Oil Cooler was added. The car is ready for HIN, but ....

 

yes our JDMZ have 2 row

 

Anybody know the weight difference between a Koyo 36mm and 54mm radiator?
