Planning on upgrading my cooling before the summer comes been looking the pathfinder mod and gtm hr mod, curious to hearing the feedback between the 2 which is better. I have a 03 g35 sedan with high mileage and I live phx, AZ with hot summers.

 

You shouldn't need this, but interested in hearing the results.

 

You're only concern should be how the fluid in your radiator is flowing, that there's no blockage and your fluid is fresh. Are your radiator hoses in good condition? Nissan designed your cooling system to operate under all conditions, even AZ

I know the mods are not a most but I am planning for getting it ready for twin turbo setup. Throughout the year i am going to do all my suspension then next year going to rebuild the and twin turbo it. So even if everything is flowing right in the cooling the mods are just another step to make sure everything keep cool as possible.

 

For twin turbos, doing the HR style routing may be beneficial due to the lack of space around the engine. Different turbo kits route their piping differently so do the research on that or be ready to find a shop that will do custom fabrication. From my experience, the Greddy TT and pathfinder cooling mod don't mix well.
