I picked up a turbo'd gt the guy couldn't get running. After fixing Tom's of half assed ****, I have it running solid on E85 @10psi.
My question is, I only see the one IAT sensor that would have gone in the stock air box. I have it currently plugged into a hose that comes from the lower right of the TB, I know it's not getting air flowing past it, but at least It gets manifold air temp.
Does the MAIT sensor from the MR2 have the same values so that I can thread it into the charge piping to properly get it in the airflow, or is there a way to get the factory sensor in the airflow and secure it from blowing out?

your thinking is correct, but wrong. IAT is Intake Air Temp. its intended to monitor the intake temps. Now with that being said, when I has my 5S turboed, I did what I posted before. I used a GM sensor and tapped the charge pipe before the throttle body and put it there. On my supra and All-Trac, I actually have the sensor right after the TB in the manifold. It works just fine. Temp corrections are very minimal, Its really MAP sensor that does most of the tuning.
