Normally, people hate on engine-swapped Mazda RX-7s, as changing out the stock rotary engine makes the car too normal, too simple. This guy went the opposite direction, with a homebrew turbocharged and supercharged Toyota 1JZ straight six.
In the 1980s, Lancia developed a supercharged and turbocharged (aka twincharged) engine for their midengine/AWD Delta S4 Group B rally car. The idea was the two compressors would eliminate any kind of lag in boost. It doesn’t look like it worked out that way.
Yeah, I know the trend right now is to bash turbocharging as we wail and moan about the inevitable death of natural aspiration. But automakers have done some really cool stuff with forced induction over the years.
