I am almost finished with the rb25 swap, and need to knoe a few things before really hitting the road with it. My oil pressure is high, like around 100 when I accelerate, and my engine seems to run really cool. the gauge on the 240 dash barely ever even comes up saying its warm. I have the stock 240 rad with a 2950 cfm fan. Its hard for me to believe that it runs that cool. also, can I run it without a intercooler if I dont get on it? I'm kinda in the red right now. Any help is greatly appriciated.

 

if your fan is on all the time, it will run really cool like that, how did you wire it? As far as the IC I'd take it easy and run premium you'll be ok. I don't know what to say about the oil pressure I'm not sure what these run normally, what weight are you running?

 

I have my fan wired to a relay which is activated by either the probe type "thermostat" or by the switch inside. I am just worried that with the 240 dash and gauge and the rb sender, if the voltage could be causeing the gauge to read wrong. I am also running more water than antifreeze with redline water wetter. I spent so much, I just dont want to hurt it already. as far as oil weight, I'm running cheap non synth castrol 5w30 for a short re-break in period. And anyone know a good speedo fix thread? Thanks.
