A client approached Schraders Speed & Style in Azusa, California to swap a LS1 into their 1969 Triumph TR6. After measuring the engine bay Schraders recommended the client go in a different direction and use a RB25DET from a Nissan Skyline R33.

Besides the RB25 being a better fit, the engine choice kept more in the “spirit” of the original Triumph engine also being an inline-six with a similar displacement. The power was greatly increased as well. The engine running on 10 psi of boost produced an estimated 380 horsepower.

Even though the engine made for a better fit, it still required a lot of modification to work. The steering rack was moved and the steering column and firewall was modified to clear the turbocharger. Schrader also had to make custom turbo piping, intercooler, and radiator to fit inside the small engine bay.

The limited slip diff was sourced from a Infiniti Q45 and used custom adapters to fit the halfshafts. The front suspension was updated with new lowering springs, new shocks, larger disc brakes with Toyota calipers. The rear suspension was upgraded to coil overs with Nissan 300ZX discs and Wilwood calipers.
