To do what?

If you're considering installing it in a 123 car, you'll need a lot more than just the engine (transmission, custom engine mounts / driveshaft / exhaust / etc.). The modified 617 will take a lot of money to have the same power as the stock 606 turbo, and the 606 turbo will do it quietly, more efficiently, and without smoke.

Pros and cons to both.
