Have any luck?

Sorting out some tunes with Chickenman. Thanks, let you know how it turns out!

Good deal- Richard will get you heading in the right direction . It's a bit of a steep learning curve - at least for me it was , but with some guidance you'll figure it out

Just a note on engine temps. 180 degrees is fine on a Datsun L-series motor. Regarding thermostats. I'd recommend that you buy a factory Nissan thermostat. They are still available from Nissan dealers. Many of the aftermarket stats have sloppy tolerances with opening and closing temps. Even the premium Stants. Also, the factory thermostats have a 30% larger flow area than the Stant recommended model. 

I think can see an Aluminium rad and dual fans??? If they are a decent size and the fan(s) pull enough air ....engine Temps shouldn't be an issue. Only issue is if fan setup does not pull enough CFM. You can go either expensive with Spal fans... or inexpensive with Ford Taurus Fans or Volvo fans. A favorite of the forced induction crowd.

Yeah, the rad is a dual core aluminum with dual fans. I don't think its a problem. The former owner said that he made the fuel/air mixture rich because that would keep the engine temp low. Don't know if that is correct, but I think he covered all those bases with all that air flow up front, including a intercooler set up for the intake. I just got back home so I will have to check to see if there is a thermostat in there. I thought I saw a receipt from Nissan on that but I am not sure. If not I will have to see if I can get one from Nissan.

Your A:F isn’t rich. Quit saying that. You’re making me nervous for your motor. You should be in the 13.5 - 14.0 range until you’re approaching WOT. Then go richer. 12.5 - 13.5.

your injectors are fat as f***! Green Giants might be a better option.
