So I have an RX200 with a Doge V2.. I'm building with 22g Kanthal. What's the lowest I can go and how big should I go? I have 1.5 mm, 2mm, 2.5mm 3mm, 3.5mm and 4mm to wrap with (I'm using a jig) How many wraps should I do and how low should I try to go? I'm going to use http://www.steam-engine.org/coil.asp to help me out.
