As promised, here's the list of materials I used and some of my notes.
Also, since I had to order more than I needed, I have enough to make 4 more blocks with nipples. If anyone is interested, I'll make it for you (first come first served), just cover the cost of materials (roughly $10) and shipping. Just send me a PM. I've already cleared this with @

Notes:
TMAP sensor fits into a 12mm dia hole, runner wall thickness there is 1/2"
TMAP probe length is 7/8" long so 3/8" of the sensor is inside the runner which how much of the sensor tip is open to air flow.
15/32 is .46875
12mm is .472441
difference .00369
1/4 NTP threaded hole requires 7/16 pilot hole
