I wanted to see how much money we saved or how much extra we spent by going with a single engine desine, so I added all the parts up that we wouldn't need for a dual engine design. It came to $304.29 which is much less than a brand new lift engine would have cost us. The $304 dollars is without the variator, but if we ever decide to buy a variator it will put the total up around $800 and this is about the same as a lift engine would have cost us.
