Hi guys
I want to fit some gauges to my car.
First question is: where is the best place to put EGT probe? dump pipe or manifold?

How do you drill and tap a 1/8NPT thread?

I have a high mount manifold with the provision for an external wastegate. Do you reckon I could install it in the blanking plate thats on there?

Also, is this the line you install the boost controller and boost guage tee on? Do you put the tee before or after the boost controller in the line?

Where do you usually run your PCV breather on top of the rocker cover?

Cheers
