two ways this can go, he can do it all properly and fully rebuild the series and the cadi engine and have it all machined and get perfect (and just from doing an engine re-build in this way I know how much this costs and how long it can take to get it right in your spare time, particularly with odd ball engines and high performance parts and machining)
Or he can do it the way he is going, I dont think it will be legal or safe and if it does work I dont think it will work for long but it will entertain us all as it goes a long
