Welcome back Ben...sounds like you have a good handle on it...I have the same car, 74 1.8, sold the engine 20 years ago and started my 914-6 GT project. Finally got it off to the painter, then this winter start putting parts back on. I bought a 2.2 long block with S pistons and cams (E engine), still need carbs. Front suspension from Rich Johnson with raised spindles and Boxster calipers and his engine mount and oil tank, tin. Also in Wisconsin. Best, Mark
