Dropped into my FD chassis RX7 it would probably weigh out to 2,600 lbs wet. Nice power to weight ratio. Someday....
My 5.0 RX7 makes that power easily and weighs the same as an A/C and P/S equipped 12a, you would be considerably heavier.

I wish Ford hadn't gotten high and mighty with all of that overhead cam stuff in the mod motors. A factory aluminum modernized small block ala the LSx-en would have been sweet. Instead they came up with an engine that is low on power, big on weight and girth. Design my own engine? My LS3 rocks!
Rather than design it... For most applications I could just fetch a BMW S54 3.4L six out of an E46 M3.
The other apps I can think of require Yamaha 1L power, LS2 V8 torque, or S2000 revs... but damn if that BMW motor wasn't sweet enough that I'd probably try to use it anyway.
Falconer V12. Two stage two speed supercharging.
The Mini-Merlin.
Two-stroke, single cylinder, 50mm bore, 50mm stroke so 100cc. 24mm carb feeding a case reed valve. Carburetor adjustable by screw position from underneath (to prevent adjustment midrace). Internal water pump and an Audi 5000 heater core as the radiator. Oil miniautolube pump driven off the water pump drive gear. 167 degrees maximum opening for exhaust and boost exhaust port. Direct drive to rear axle via chain. CDI ignition with a rev limiter at 17000 RPM. Ignition, water, and oil pumps to be specified for the series and inexpensive, probably American-made for the last two.
About 27 hp. If this sounds like an ICA with a couple rules to make it cheaper to run, that's because it is!
2.25l miller cycle with the bottom end lightened and balanced. Bring the boost up to say 30-35 psi. Upgrade the internals, gaskets etc as needed to make reliable
Edit: Ohya I forgot to make it so it can be mated to a RWD car. FD or FC RX7 or how about stuffing it in a miata. I am betting on about 400 / 400 may be more. I just love the design of these motors. I think that there potential has been overlooked has been overlooked by Mazda.
Or this animal that Bill Sherwood came upon"
A Toyota 1G-GZTE, which means it's a 2 litre, twin cam, four valves-per-cylinder, 6 cylinder, supercharged AND turbocharged 450hp monster!
I want one!!!
Desmo Hemi
I really like the idea of the hayabusa V8 it just needs a good sized variable geometry turbo. I would almost kill a baby to have one in my chevette.
Maybe take this concept and make some bigger motors with heads from badass car motors
SR40DETT V8,
RB52DETT V12,
3.2L V8 with chevette heads
another one I think would be nice in my car would be a Short compact W8 maybe 3.0L All aluminum block and head, bullet proof bottum end and a turbo. 10000 rpm would be nice too.

When you say "almost" do you mean you would maim it to the point of near death and then stop, leaving it like a bloody rag doll to go pick up the motor?

Well I thought that what I said was sick enough on it's own but you really stepped it up.
And the answer is maybe.
I am fairly sure that the perfect engine has already been built. BMW put it in the back of the McLaren F1:
Warning... Engine p0rn to follow the link...
V12 DOHC 48V Solid Lifter Valvetrain with Single VANOS and Individual Throttle Bodies
I would love to hear that Bimmer rev to the moon!
I want a low-profile, all-aluminum flat-eight.

I like the new avatar, Jay. That's a bold claim to make 'round these parts
I had an original thought last night...
I want to take a 1996 Neon DOHC head and a 1996 Avenger DOHC head and install them on a 60* V8 block with 8 SRT4 pistons and rods on a forged crank. The engine will be a twin turbo design with SRT4 turbos.
500hp 4.8L DOHC turbo.
3.0 Liter Horizontally opposed (boxer) 8, ~10:1 compression (oversquare of course), 4 valves per cylinder, two small turbochargers (think T25's), ~10k rpm redline and ~10lbs of (intercooled) boost. ALL ALUMINUM.

Are they the same head but reversed?
Here's a unique powerplant, based on the old Fiat-Lancia twincam. Alternating intake and exhaust valve, so you can drive two turbos on an inline-4 equally. For a more descriptive explanation: Triflux engine

Yes, yes they are ;)
Neon 420a is mirror opposite of Mitsu 420A.

Considering this little bit of information, I'm amazed nobody has done this yet.
How about a crankshaftless engine? Double-sided magnetic piston, double-acting, and a coil on the outside of the cylinder.

So it effectively becomes an alternator?

I'll see your idea and raise you more inefficiency!
How about a gas powered generator in the trunk of your Prius!
You could tie it in to the electrics for extended range, plus you could use it for even more blinding horsepower. Just think, mash the gas and the electric motor, PLUS the gas engine PLUS the onboard generator giving you power!
Or you could just go with the DEI system: http://forums.finalgear.com/general-automotive/id-like-to-introduce-you-to-dei-dir...
