The flagship turbocharged, fuel-injected and non-intercooled variant of the E5 was the E5T.

limited-edition package of just 300 cars released in June 1985. The engine started out as a normal E5S and then an IHI RHB52 turbocharger was fitted, setup in a blow-through style, with boost limited to just 5.1 psi (0.351632621943 bar). A modified version of the stock carburettor known as a "Solex 32 DIS (turbo)" was fitted to provide fuelling. A Compuspark ignition system with knock sensor was also added to prevent engine damage if the driver ever used a lower octane fuel than the 97RON that was recommended. As the carburettors were not boost referenced, they were difficult to maintain and often suffered from float rupture or excessive flooding. Unlike its more reliable fuel-injected counterpart, the E5T carb turbo setup was notoriously difficult to maintain and some cars had the turbo systems removed instead of having them replaced.
