I can understand fully. When i did my car, it pulled every last strain of money/being out of me. I managed to get it running---what a crazy ride. But alas, i did sell it very shortly after that.
Am i glad, well yes and no. But i think in the end i am much more happy without the headache of a high strung car. Of course i resorted completly backwards and bought a 25HP 1920 Model T pickup. But i did also buy a older Dodge pickup to mess with---but again much more plain jane.
I think if i were you, i'd finish it as is and drive it---it seems you dont have intrest in selling the car itself, and a turbo setup can be much more docile than a 800hp N/A motor. If you were going to sell the whole car, well then thats another story up for serious consideration---and you'll probably loose big like i and alot of people have---i sold when the market was still decent at least.
