Don Groff’s Custom 1JZ V12 Runs – Update 10

Custom twin-turbo V12 made from two Toyota 1JZ engines

Nth Moto is helping hot rod builder Don Groff with his custom twin-turbo V12 with 1JZ heads. In our previous update we said Nth Moto would be releasing a startup video and now we have it. The engine runs on ethanol with two Garrett GTX turbochargers and an AEM Infinity ECU. More tuning is coming and hopefully some dyno numbers.

Update 1-16-2018 – Added new video of the engine revving below

  1. I honestly want to take a closer looks on how the engine block are made… are they still a crankcase + 2x 1JZ block like earlier prototype?
