I fitted a koyo to mine and that was huge compared to the stocker. I also discovered it was a bit too thick. The a/c drier (the silver round cylinder by the passenger headlamp) was actually fouling the bonnet which meant it wouldn\'t close. Best thing to do is cut the corners off the radiator fan frames to allow easier fitment of the fans to the rad and also to allow the drier to sit lower.

Well fitted it today and what a struggle :2eek , had to take the rad out a few times as the small brackets at the side would not allow the rad to go completely down so leaving all the intercooler and ducting sticking up and unable to mount, but a few mods of the fan housing and brackets made for a tight but perfect fit.

Temps are a little lower at idle about 5c but thrashing it and the temps stay 12-15c lower and they are very constant.

Overall very pleased and even had the time to fully flush the cooling system with just water.

Ah well was gonna take some piccys of the installation and mods to make it fit correctly but didnt think there would be much interest so didnt take any :(

Ah well.

The rad when installed is vertually hidden as its standard mount and i have aircon fitted so its also behind the aircon condensor, guess removing the aircon would prove to lower temps even more.

Im intending on removing the aircon soon anyway so i will take some piccys of the rad then.
