You can of course chose to combine the 800cc engine with a XL billet-steel crankshaft, this will result into 850cc. If you do want a big engine, and you also want an optimal driving comfort (depending on the use of your car), we do recommand you the 760cc engine in combination with a XL billet-steel crankshaft; this will result into 810cc and you will have lots of torque, while it will still be comfortable to drive both road and offroad.
