This may not make you guys happy
I'm looking into makeing an fun realitively fuel eficant (realitive to my subaru: ~22mpg) car. Because of my love of Rx-7's of course I'm trying to think of an engine swap that would acomplish this. The car already has the key engridants I want: it's light and rear wheel drive. So the engines I've been thinking about the most are the sr20det (nissan) and the 4age (toyota). Please give any input into this you have as well as your questions of why. Thanks.

That's funny, I've always thought of the ~20mpg of my stock 12A as fun and fuel efficient :P (But I judge everything in MilesPerDollar now anyway....)
I suppose you're thinking of something with more horsepower though
So why this thread and another thread talking about a 13B NA swap? Two different cars?

Ford Zetec or Duratec!
Mazda FE3! (easily found in Kia Sportage)
Ford CVH! well, maybe not.
Saturn LL0! (if you can fabricate your own bellhousing)

I wouldn't go for the 4AGE. I know a friend that's pushing an 85 Corolla with one in it...
The SR20DET, if I'm thinking correctly, is faster than the 4AGE and would still get good gas mileage.
I don't think I've ever seen an SR20DET swap into a first generation RX-7 though...should be interesting.

But those are Focus engines. 
The best US-market Zetecs were in the ZX2s. They had stronger blocks and cranks, and of course the variable exhaust cam timing.

I'm getting just over 20mpg in my SE, and I like to drive it 
.. I mean drive it hard now and then to show people what it can do. I'm sure I could probably stretch 25mpg out of it if I drove like a granny but thats not me
20mpg and performance = good.

Honda engines (up until the K series) rotate backwards. Which is fitting for an ***-backwards car.

The Kia Sportage has a Mazda engine, but it's not the FE3 that you'd want. The one you'd want is the jspec one, and that would have to be imported. It's a common topic for swapping into 1st gen MX-6/Probes because that's what car it came in in japan.
I get 22-24 mpg in my 1st gen (with 226,000 miles!) so getting 18-20 with more power would be quite good.

Focuses also had heavy flywheels and absurdly tall gearing. ZX2s had the lowest gearing available in either an Escort or behind a Zetec, in the US anyway. (Focus, being a European car, had the MTX75 transaxle. The Escort and ZX2, being mainly Japanese cars, had the Mazda... crap, can't remember the tranny code. Same as used in the 323/626/MX-3/MX-6/Probe/Protege/etc.
Still trying to find out if the clutch-type diff from the Mazdaspeed Protege will work in a ZX2 tranny. ZX2s eat diffs for breakfast, lunch, and dinner.

That's a K-series.
Why bother with an S2000 engine, the Fod Duratec (2.3l, as found in Ranger pickups) can easily make *more* power than a stock S2000, without touching the camshafts or cylinder head...

Simpsons did it.
No, seriously, search the FD section - someone did an SR20 swap into one of those.
Myself I'd prefer the Duratec swap - all aluminum engine.
Or the Saturn swap, for the same reason (the block weighs less than the CRANK!) but that would be a tad more tricky.

Nah. Festiva engine. 1.3l B-series, will bolt up to a Miata/B1600 transmission, which is the same mechanically as the RX-7 transmission and you can mix and match housings to have B-series bolt pattern at the front and RX-7 shifter position/tranny mount in the back.
And then you realize that you could throw 323GTX bottom end stuff at the engine and run scadly amounts of boost into it. I still wonder if the head from a 1.6 SOHC or even 1.6 DOHC would allow the valves to clear the 1.3's tiny bore.
Then again, you'd probably get better mileage with an LT1 swap.
