Pick up his gunner, then turn around and go to town on the oncoming enemies. Following the cutscene, use your gunner to take out the cars.
When the Gangcar shows up, take out all enemies on board, then take out the Vultures overhead (using your leash is most effective for this). Do the same when the Gyrocopters arrive.
When Ishi warns you of the torpedo, look for it in the ground to the left and blow it up. Keep an eye out for another one that will come from the right.
