I think it is Tiger Japanese in Toronto. I have not bought from him. Sunrise in Montreal, I have bought from 3 times.
Then down to Japanese engines inc in Patterson NJ, I have bought from them 3 times also. They have one now for $650 USD.
The engine should cost you no more than $650USD plus shipping. If you can ship into Detroit you are golden and the shipping should not be over $300.
If you look on eBay under 6G72 you will find close to a half dozen 12V engines.
These engines come out of cars so you will need to swap over your external parts.
