MOUNTING SENSORS + SOME INEXPENSIVE AUXILIARY GAUGES

If you have followed our builds for a while you might realize one thing - I'm kind of cheap (usually to my determent, then I learn a lesson, and don't make that mistake again). Hey, when you're building...

Project update for April 14, 2026: A lot of work has been going on here at Vorshlag on the J37 V6 swapped FRS, and we've actually started the engine and driven it now - and it sounds great! I will post again after the dyno tune and first track event, but let's catch up on about 3 months of the intense...
