1980 Nissan 280zx, replace engine with a Nissan TB45E straight six out of a construction/retail vehicle. Add DOHC head from TB48DE. You now have a 4.5l DOHC straight six making 280 HP. Add boost. Lots and lots of boost.
The 280ZX is better than a 280z for this because of the added length and height of the engine bay.

*Cough* Not forgetting the considerable aerodynamic improvements I keep repeating myself about...
Also, the TB only revs to about 4200 RPM, right? That's pretty lame in a sports car...

The aero was so much better .
With the improved DOHC valve train, you could probably use aftermarket springs, valves, and cams on ported heads to pull that redline considerably higher. They were known as rock-solid motors in the Patrol, as far as I know, so the performance benefit might be there. The 48 was DOHC, but it was long-stroke and dropped revs a little bit too in favor of more torque.

To drive the point home, looks like this TB48 build (so even longer stroke than the TB45) was making 560HP @10 psi at around 5800rpm.

It feels like you could have even more fun with that in a Baja-prepped/Sandrail-ish Patrol, but nonetheless a 450ZX Turbo should be just lovely insane!

Ford 2.0 CVH from a Ford Escort, with the short 2.54" stroke crank from the 1.3l, making a 1.6l engine. Use the heads and turbo from the Escort RS turbo and you'll be able to rev as high as you can still flow air. (the RS turbo had a much longer stroke, and only went to 6000rpm) Port the heads open and crank the boost up over a certain RPM level, and you'll still have low piston acceleration levels even at 9000-10000rpm, so if your valves and boost can keep up, you should be able to make insane top end power and still have low-end economy to the tune of 300HP out of a 1.6l engine.
Of course... since this is insane project cars, I'd make a wide-angle bank out of two CVH motors with a custom 2.5l" crank and casing to make a 3.2l V8 twin turbo.
