Hey all, been slow working on the 153. The plans have changed somewhat. I have decided on dropping the turbo and am now building a supercharged 153. Everything else is the same. I will be using an Eaton m45 from a Mercedes 230. want to push about 8 to 10 psi for now. Anyways if anyone wants to buy a New SPA turbo manifold for a 153 let me know!
