They cut an engine in half for this guy?

What about the D16A6 that came in the CRX SI? The rest of the world gets a dual cam engine with 20 more horse and we get some M3h machine.
You obviously know not of which you speak.
The D16A6 would probably crack the top 20 motors of all time.
Easily revs to 7800rpms all day long and makes power all the way to that number with a few minor bolt-ons.
On average, will run 250K miles with nothing other than minor maintenance. No oil leaks...nothing. Also, at said mileage, will usually dyno within 5-10% of the HP figure that the engine made when brand new.
Has a very decent flowing intake manifold and head. Responds well to modifications, too.
Even when mated to a somewhat "short" gearbox, it'll still get 40mpg all day long.
Is very light in weight
It is only rated for ~108 hp from the factory, but a dyno will usually result in a stock motor making over 100hp @ the wheels.
There is nothing to hate about this motor. Japan got a DOHC version of the motor, but the SOHC version the US got makes more torque at a better RPM.
This motor is one of the key ingredients of the 89-91 Civic Si's success in Solo II ST classes.

The hugely disappointing Vega Cosworth: 2.0l of stillborn pedigree poo poo.
"GM had hoped to introduce the Cosworth Vega by the start of the 1974 model year but, alas, due to the government's newly - revised emissions regulations, this deadline couldn't be met. It wasn't until March 27, 1975 that the production of saleable Cosworth Vegas got underway at the Lordstown, OH, plant. But a lot of things had changed along the way. Way back in 1971 when McWilliams conducted her feasibility study, 185hp was the power figure being quoted; by 1973, however, the figure had dropped to 130hp and, owing to Chevrolet's concern for a smooth, quiet - running engine, the horsepower rating was down to 110 by the time the production version finally made its debut."

In reply to Shaun: In the early '80s I raced with a guy that had a cosworth vega that ran 12's in the quarter, with just the usual improvements.

Made 180hp, it's only redeeming feature is that is the sweetest sound V8 sound ever.
There's a James Bond film with a Stag in it and that indeed sounded the business. But if that's all it has going for it, a 3.5 swap and maybe a good exhaust system w/ an x-pipe seems like an excellent solution.
I am building one as original, just a few reliability mods, the other is looking like a Mopar Big Block, just because i can....who ever heard of a Ratted out Stag
