Part 1 of Gran Turismo 7’s Spec IV update dropped today (15th October 2026) and alongside new cars, Sportsland Sugo and a few new features, comes the inevitable engine-swap madness.
Of the new cars, the Honda Step WGN Spada Premium Line ’23 features an unheralded three engine swaps, including a K20C1 from a 2020 Honda Civic, a Windsor-351-Maverick V8 from Greening Motor Company and a frankly insane V12 block from the game’s fictional F3500-A ‘90s Formula 1 car.
The real star of the V1.72 build is the ability to swap a B18C Honda Integra engine into the new Citroën 2CV 6 Charleston ’86, offering high-revving, VTEC-assistance to the little French car’s default 28 bhp.
The Integra engine can also be transplanted into the Honda Civic Si Group A version ’87, but that’s nowhere near as hilarious.
It’s also possible to swap in the beefy W16 powerplant from a Bugatti Chiron into a legion of Lamborghinis (where’s the fun in that?), while the classic Mini Cooper gets the Honda RC213V MotoGP-derived engine intended for the Project 2&4 concept. That’s more like it.
All the new engine swaps featured in GT7’s V1.72 update can be found below.
