Defintely talk to Ryan, he has worked on my NA and Turbo. By far one of the best mechanics around. Actually he drove my car yesterday and diagnosed my problem instantly, fixed it the next morning and everything great.
Seems to know these cars like none-other, very nice guy aswell.
I thought my car was running hot aswell, but turned out the temp gauge was out.
Have changed the thermostat or bled the system?
