EGT Probe Installed

 The Prosport EGT Temp Gauge Probe installed on the black Starion.
The probe have a 1/8" npt fitting, i installed it in the #3 cylinder runner because of the desing of the intake manifold in the Starion/Conquest the cylinders #2 & #3 run leaner than the 1 &4.
If you want a better and a much more balanced a/f mixture on each cylinder on your Starion/Conquest with the stock tbi(good for adding more boost,upgrade turbocharger etc..) i recommend using a caravan 2.6 (84-87) intake manifold and modified it to fit the stock Starion tbi system (because the caravan intake manifold's came oem to use a carburetor) ,that intake manifold have a straight runners desing to each cylinder and allows a more balance air and fuel mixture in each cylinder.

Here is the EGT probe installed..

Here is the stock Starion intake manifold look the Y runners desing.

Here is the Caravan intake manifold look at the straight runners desing .
