Switzer reckon the Nissan GT-R USE can be used as a daily driver, as it sill has air con, a subtle sounding exhaust and still delivers great MPG. Okay, that last bit was a lie.
Upgrades to the VR38DETT 3.8L engine include twin liquid-cooled turbos, a massive intercooler, a new front-mount radiator, replacement pistons and camshafts.
The Nissan GT-R USE also features a Shepherd Trans gearbox and custom lowering springs, however it keeps the factory electronically adjustable dampers.
