The Blast Buggy wasn't in SPD. As I understand it, Power Rangers doesn't always have license to use footage from the Sentai movies.

Not sure about the other one because I avoid Go-Onger like the plague so I have no idea what it is.

Rpm never got to use engine dai shogun and jungle fury never used gekirintouja without the huge rhino

Engine DaiShogun.

Engine Dai dai dai dai dai DaiShogun.

Radiacar from Carranger didn't appear in Power Rangers Turbo, I believe.

The Blast Buggy was "used", but only in accordance with the toyline. It was released as a set with S.P.D. Red and Blue. Bakuren'oh was a mild oddity as it had a 5-inch figure, a different looking deluxe version, and was used in the show as the "Replicant Zord". Some Zords or Mechas were seen in the show, but never got U.S. toy releases. The Lifeforce Megazord from Lightspeed Rescue could also be considered as GoGoV had all-black versions of Victory Robo and LinerBoy for the toyline. The Wild Force Elephant Zord was also never ported over. Some of the spheres from Hurricanger/Ninja Storm were omitted. The Dino Thunder Cephalazord also never made it. Wolkaiser from Magiranger was already mentioned. Starting with Overdrive, the Zord Toys started to differ from the Sentai versions. A deluxe version of the Flashpoint was also never released stateside.
