Yeah, I had a mate do the radiator, when he machined the head. The temp sits on about 1/3 of the gauge and dropped slightly again, since the water pump was recoed, last week. This engine has so much potential to get some noteworthy figures with some mods, (EFI and Turbo) but finances won't permit it. Also, I like the simplicity of the set up. It's strange that Mr Nissan didn't even bother to put fuel injection on, as both dunny doors and skylines came out with it.
