What you see in there is a single-turbo, inline-6 2JZ-GTE, the infamously tunable engine that was developed for the Mark IV Toyota Supra. And the car it is in is a 2006 Corvette C6 Z06.
These two sentences generally don’t belong together. Yet…
While the LS7 from the original C6 Z06 is no slouch, there is a method to the madness here. The 2JZ, even with a single turbo and on the stock block, manifold, and internals, can hit damned near 800 BHP. Twin-turbo built engines have been known to hit upwards of 1,500 BHP.
For this car, they are reporting the turbo running at 1.4 Bar, or 20.3 PSI. The dyno shows 679 WHP, which is not bad at all, considering the stock C6 Z06 came with 505 BHP with two more cylinders and no turbos.
What’s more impressive, is that RSG somehow made the 2JZ’s output shaft mesh with the C6 Z06’s standard transmission, meaning it uses the original gear ratios that the car left the factory with. In fact, apart from a couple of engine mounts, the Corvette is almost completely bone stock normal.
While this does get filed into “… why?!” category, and for some Corvette purists, maybe even into the “blasphemy” category, it is undeniable that this looks to have been done professionally, perfectly, and you can never get sick of a 2JZ’s blowoff valve twittering away.
