The Supra in the piece of footage below serves as the perfect example of this, having been built by tuning specialist Real Street for a customer who came with specific requirements - the man wanted a 7s Supra that would remain fully streetable.
The Supra was never a light animal and, in this mix that combines goodies such as power windows with lighter parts, the Toyota tips the scales at 3,400 lbs.
Nevertheless, the engine compartment sees the machine's 2JZ straight-six being gifted with the tuner's RS1600 kit. And yes, this means the crank output sits at around 1,600 ponies.
Most of the credit for that extreme hp number goes to a Precision 8685 that has been cut down to fit Streetfighter class drag racing regulations, while a 150 shot of nitrous is also at hand.
This Supra can now deliver mid-to-high 7s quarter mile runs and the first element that would have to be changed in order for the drag strip performance to be improved is the street coilover suspension. But playing with that aspect would affect the drivability, thus defeating the aim of the project altogether.
In case you're curious how this Supra launches in the current setup, the piece of footage below will quench your velocity thirst.
