Awesome build mate, I'll need to check out the youtube series. Theres a lad near me that stuck a K20 in his mk1, sure he mentions there is less wiring to convert than if doing an ABF swap, and i think he was considering creating engine mount kits for them for others to buy. Seem like great engines.
@Savagesam did something with converting the speedo on his build I think. I assume you're wanting to convert it to electric? Very cool build btw!
