Does anyone have any pictures of TPI installations? I am wondering what to do with the air temp sensor. Also, do I have to modify the TPS to clear the strut tower?

Thanks!

The answer to the second question is "yes". I'm not sure about the MAT because mine is speed density. I spoke with Archie on the phone the other day about the TPS and he was going to e-mail me some good pics of relocation of the TPS. He said it is raised about 1.3-1.6". I have not gotten those pics yet but when I do, I will share them here.

Cool. I will be using Mega Squirt to run mine, so I'm going to need the MAT sensor. I also need to get one of those 90 degree intake snorkles.

Great TPS tip. Thank you.

Now, what about the air temp sensor?

generally, you want the MAT sensor just before the throttle body, or at least near it - after the air filter, in the air filter box is fine, like the stock Fiero setup - keeps it clean & safe.

The Air Temp sensor screws into the 3/8" NPT hole on the underside of the upper part of the TPI manifold. About 4" forward of the center of the distributor.
