E; cooling system upgrade (but I prefer OEM radiator)
the water pump is brand new I just changed it a month or two ago. It pressurizes just fine to oem specifications and you know damn well Its got the OEM thermostat.
some creative ducting might help; the issue here is not so much cooling as the fact the engine should not be sitting at 3500+RPM for any length of time, regardless of whether it overheats or not. period.

The truth is... If the new owner understands the risks of operating the antique engine at 3500+rpm continously on the highway.... then I would simply recommend a bit of creative ducting or an upgraded radiator as a permanent fix to this "problem". JUST REMEMBER to add an oil cooler ALSO. And the reason it was never a "problem" for me was because I understand the limitations of the antique redtop engines having owned several of them in the past and I knew that I could never bring myself to steady cruise at 3500+rpm on the highway, therefore, an upgraded radiator was unnecessary.
You cant ask for anything more than all oem equipment and every possible nut and bolt in the right place with the right torque specification. Thats exactly what he is driving. This is not a "build" this is an OEM engine with full oem equipment and around 50k miles tops.
And disconnecting the turbine is a GREAT way to preserve the life of the turbocharger AND the life of the engine oil on these redtop engines.

I installed a mishimoto radiator, kept OEM fan and shroud, kept same hoses, and I successfully drove from my house to miami (50 miles).
So the radiator fixed my heating issue.

Apparently I was still wrong after suggesting a new radiator as one of the options (twice). Shows you how well people can read.
