i finally got my dakota digital EGT gauge installed
and suprisingly it went in fairyly easily

it came with a weld in bung for exhaust pipes
i opted to just the screw in fitting straight into the hahn manifold

1/4"NPT threads so it was a large hole 7/16th to be exact
and then the probe screwed down into that fitting

i tapped it between the 3rd and 4th runner
i wanted to tap straight into the 4th but i was worried about fitment issued with the IC piping because the elbow coming out of the turbine was in the way

btw
tap magic on a steady drip onto the tap works wonders

to seal the threads i used a product called Inferno it is marketed as a manifold weld

it is supposedly rated to 2000 degrees

i still need to tie up the sender wires under the dash so i really cant go out and drive it yet
but i am getting about 850F at idle

thts normal. at operating temp

EDIT: negative. we put the egt in the dumppipe on the silvia, yours in is the manifold. i don't know what the difference would be between the motors but I know there is a diff between the manifold and after the turbo locations.

If it's in the dumppipe you'd only be getting readings when your wastegate would open up. You mean downpipe?

I have that same egt gauge and love it!

i was really happy on the track last night with the egt
at 11 psi crossing the trap my egt was 1450

probably too low because i am running insanely rich
but at least i am not melting anything (i hope)

850 at idle after warmup is dead on.
