Hi Duke,
My info on the Nissan TD42Ti says:
"Intercooler: Although similar in design and fitment as the intercooler fitted to the RD28 and ZD30 Y61 variants, there are some significant differences.
1. Deletion of the charge pressure sensor from the front of the intercooler.
2. Shape and diameter of the inlet tubing.
3. Deletion of the cooling fan from the underside of the intercooler."
So, it would seem a fair bet the fan from the smaller cpacity models would fit OK. (And by the way, point 1 above suggests a ready-made port for connecting a boost gauge, if you wanted to.)
I'd think the fan would definitely help in low speed, high load situations. As it is, at low speeds I imagine most top-mount intercoolers having a net UPWARD flow of hot engine bay air through the IC and out of the scoop. That's because the main cooling fan(s) are running at high rpm, slightly pressurising the engine bay with hot air.
If you do fit a fan and want to loan me your vehicle for a few weeks, I'll fully instrument it and tell you how well it works,OK??
