[s-cars] Aquamist Impressions-WAS DIY FMIC - Almost done, hit a small snag

Wed Jul 28 16:05:49 EDT 2004

Forgetaboutit, it's designed to last and at worst, you drill and tap
the manifold or scroll and replace thermocouple as needed.

I use the SPA EGT gauge, but I have a VDO on my shelf.  You might also
want to look into Greddy, Defi and the other usual Jap stuff.
