ssslpr how much are you willing to spend on the cooler including installation ?
I got mine done for a bit over $2K, its a full custom job and uses all the holes the original cooler used so no cutting involved.
The cooler itself is 600x300x100. These are the dimensions I wanted and there were no bolt on jap ones that had these dimensions hence the reason why I went custom.
Job was done by Race Solutions in Penrith.
