Thermostat and Fan switch needed?

[shebangs]

I think some people are slightly confused with the definition of must have.

Air filter on your intake is a must have, doesn't need to be there but good luck with maintaining a healthy engine without one.

And the argument regarding 'stock' is slightly skewed, as you can see my car isn't stock. So although making the assumption stock cooling is fine, although isn't wrong, I think it's worthy keeping in mind that there will be a point it won't be sufficient.

Defininately, I agree, for track, definately oil cooler, baffled sump, thermostat, fanswitch are 100% - but my question is regarding spending that same ~$1500 on a street car.
