Greetings All!
I just recently dropped off my 2.0 (GA) case and 71mm crankshaft to get checked at a local machine shop in preparation for a rebuild. Today they called and said for align bore, decking the registers, polishing the crankshaft, and mocking up the assembly with fitted and numbered main bearings it would be 30 hours of work. Does that sound reasonable? It's honestly a lot more than I expected and will add $$$ to my budget for this rebuild. Should I look for another case, maybe a 1.7, that is in better condition or has already been prepped? I'm not an expert builder and some things are worth paying for, but man that's a lot of money! Thanks for any advice! |

Made some progress today.. 2563cc for a 912E. Jake - would you share more pics of that engine room? It looks clean and functional. I post Facebook Live videos of the clean room often. I just shared one this morning, you can check it out on the Raby's Aircooled Technology FB page, as a shared video. I built this room when I moved into the new Raby Engine Development R&D facility 6 years ago. I originally didn't plan to build any customer's engines here; only do development work, and use the facility to host my Porsche engine classes. I just moved the original RAT engine dyno here a couple months ago, which completed the transition of all the Aircooled stuff into my own world. I've had several clean rooms over the years, this one is the culmination of all those before it. I work in this one almost everyday, and still love it after 6 years.

I'm rehabbing my workshop and while I don't need pro grade metal cabinetry, I like the clean look of everything in drawers and cabinets. No pegboard or open shelving for me. |

I had these made by Ulti-mate. I also am not one for exposed storage of tools and etc. |
