Well, I just got back from NSW last night. I had to go to drop off a falcon bottom end but on the way back I dropped by twincammini's place to pick up the new powerplant that is going in the mini!!
Its a CB70 turbo DOHC EFI daihatsu engine. 105hp standard. Ive got it sitting next to the original A series and its pretty similar in sizing. Its a little bit shorter, The head is a bit deeper but no wider than the block of an A series.
It should fit in pretty well I think.
Ive already started plugging the factory ECU in to make sure Ive got all the wiring I need, its pretty easy as the loom has all the plugs on it. Its like a big puzzle where you just need to find where everything fits.
Once I get my other car back from the mechanic ( who managed to clear my haltech so its undriveable ATM

) Ill get an engine crane to start working on how Im going to fit it all in the engine bay.
Hopefully getting the engine in and running doesnt take more than a few months. Then I can start on the rest of the restoration.
-Also thanks for the ride in your mini Chris, that thing felt so fast. I loved it! Its an awesome car! I cant wait till mine goes that well!
