Sleepers or as Brits prefer to call these type of automobiles, Q-cars, is a term used to describe standard looking vehicles with extensive mods under the hood. This custom-made 1985 Toyota Celica GTS fits the description perfectly as the owner of the Japanese coupe swapped the rear-wheel drive Celica’s humble four-pot with a brawny LS1 5.7-liter V8 from a fourth-generation 2001 Camaro that produces around 325 horsepower.

It goes without saying that these kind of engine swaps demand the replacement and/or modification of various other mechanical components. Among other changes, the LS1-powered Celica features a Z06 clutch, a front swaybar from a 1992 Iroc Z and a custom-made radiator.
