Hartley Enterprises' Haybusa-derived 2.8L V8

If four's good, then eight must be better - that's the idea behind this jewel-like V8 engine built by Hartley Enterprises from two Suzuki Hayabusa four-cylinder powerplants.
The 75-degree V8 displaces 2.8 liters, weighs only 200 lb and puts out 400 hp at a window-rattling 10,000 rpm. Torque peaks at respectable 245 ft-lbs (at 7500 rpm!), although dyno runs for a 2.6 liter version show a fairly flat curve. Aside from boring out the 'busa block from 81mm to 83mm, none of the wide variety of performance enhancements available for the bike version have been applied to the HE V8, so it's safe to say we're nowhere near the performance limits of the design.
Hartley's diminutive V8 is produced to order, with the 2.8 liter version priced under $30,000, depending on options. Check out the Hartley Enterprises website for more details, including video of a dyno run with the engine installed in a Caterham 7.

I would have thought it would sound better. Perhaps the firing order and narrow 75 degree banks result in the lackluster sound. Pretty neat engine, though.
The 1UZ with individual throttle bodies sounds MUCH better!
