Well since PSD have now closed i was looking around at alternative sources of this particular product & to be honest it is a bit of a mine field (this could however be due to a lack of knowledge on my part). However i have done a fair bit of research an sourced a shop on ebay which sells a specific G40 one.
Price is £105 + postage, this includes a 13 row cooler and the fitting kit 1/2 bsp piping etc.
Now in my mind this is a fair price an comes with all the bits part from a thermostat which is an extra £15 i think.
Now assuming this is to go on a G40 running arouund 150bhp its quite possible for the oil temperatures to clime very high under hard working conditions, bearing in mind the standard oil temp is around 90-100'c untill worked hard an can be up in the low to mid 100's.
Assuming the above i would of thought a 16 row cooler would be more suficient??
Any thoughts, comments welcome (even if you wana tell me how wrong/stupid i am
) go easy though
