1. the radiator mounting, if you cannot change that you need to seal that hole on top between the radiator and the support, I did this on my old couple helped a lot.
2. 2 fans will work, but you still need to seal it off so the wont pull any hot air from the engine bay.
3. shroud, plus refer to my first tip.
3. intercooler end tanks too big, get a normal one. you can still have a bid intercooler with small end tanks.
4.electric water pump is unnecessary.
5. downpipe change the angle to allow more clearance.
6. EG front end does not allow much clearance between the radiator and the intercooler, I noticed this after I change cars using the same setup my EK never overheats.
7 engine oil cooler.
8. I use the intercooler sprayer but only the track, and is only setup for boosting, your cooling problem is stop and go traffic.
9. water/methol injection, only setup for boost.
I did most of these and they worked.
