Dont know why but the people who worked on my car recommended that I put it in the downpipe. I trust their judgement since they do build Supra's allllllll the time. Last I heard, their current Supra put down 1084 at 26 psi on a conservative tune.

Doesnt seem hard, just gotta have the right drill or drill press to drill through the damn iron.

I don't know how you guys are tapping, but tapping threads into cast iron is not hard at all.

With a hammer?
jk :D

With a good 'ol craftsman set.
It is definitly doable, but harder than into steel.
It's easier to just drill a hole and weld a fitting on.

I haven't heard how good it is but I like the layout of the Zeitronix display. Even if you don't get the wideband it may be worth the cost of the display for boost and EGT. With the wideband it only gets better :wink:
