I was thinking of upgrading my radiator with either a Nismo, Mine's or Koyo item.
Anyone have any experience with one of these or have other suggestions? Koyo Al radiators seem to be very well built and cost around half the price of the Nismo and Mine's ones.
Its damn hot here at the moment. This mornig at around 10(before switching the car on) the ambient temp read 35 deg! :eek:

Impul Radiator

I had Impul install their (ie Calsonic) uprated unit. On average seems to run on avgerage 10 to 17% lower temps..............The core is substantial thicker

To install, I needed a small piece on the top of the fan shroud cut away..............

Radiator

Hi,

These days, Al radiator performance is getting better.
Nismo and Mine's radiator is basically the same and they are made by Calsonic.
Calsonic is the best.

Yours,
Shin

Hey Dino

Doing the radiator is a good idea (particularly with Japan's summer!. Definitely will get you about 10% lower temps. I've got a Yashio Al radiator on board which has about 125% more capacity than the standard R34 one. The price is about Y100,000, which compares favourably to the Calsonic equivalent which is about double the price. However, you generally get what you pay for.

You may also want to consider an uprated Thermo while you are at it.

Cya O!

Radiators

DCD,

Over here in Singapore year round the temps are hot - min 29 (at like 5 am in the morning) and usually around 32-35. I had an ARC radiator fitted. The thickness was about twice that of the standard item. It performs well - at at 80 KM the temp is about 80 C and when stuck in traffic for a while, it moves up to about 88 C. I have used on the track, and I must say is that it performs well - much much better than the stadard item.

The only thing I regret is that the Arc one I got did not come with a full shroud, but little lenghts of metal for the top and both sides.

Too Hot

Yes, the heat plus 90% humidity big downside especially when one has an affinity for turbo charged cars - would not mind the cold once in a while.
