Ok just put it on a few days ago, d16z6, t25, 450, s-afc, 8psi, anything over 50 mph I start to overheat, then when I drop below that, i'm fine. I just remembered that I haven't blead out my coolant lines since I ran them to my turbo, so that could do something, but just yesterday I drove it on the highway for like 15 mins and it didn't overheat, and now it is.

 

If your heat gadge jumps very quickly up and then right back down again when you change from one somewhat constant RPM to another, there is a good possibility that it is a bubble in the coolant. If it haets up slowly,and takes a wile to cool down, you may have a flow issue. hope I could help ya...

 

hit the cluster when it does that, if the nail goes down then its broken, if not, i dont know what to say then.

 

ok, I blead the lines and it seems to be working ok now.

 

lol.. yup it sure does .... were's jeff
