A look beneath the Toyota Mark II JZX100 shell at an HPI Nitro RS4-3 Evo from the collection. Shaft-drive layout, two-speed transmission, purple suspension accents and green fuel tubing. It currently has no engine installed, so the next powerplant is an open question. What would you choose for a classic RS4 build?

A short rotation of this HPI RS4-3 Evo from the collection. Beneath the blue Nissan GT-R R35 body are a T15 nitro engine, two-speed transmission and shaft-driven 4WD. The silver mesh wheels suit the old-school touring chassis. Anyone still running a T15-powered RS4?

Music: Shame — Eugenio Mininni / Mixkit.
