Going to look at what is supposed to be a clean AZ Midget with a vintage race legal bar but missing an engine (the Spit deal fell apart at the last minute).
What's the easiest way to get 100 WHP? Does not necessarily have to be vintage legal at this time but preference would be given to that.
Thanks
And yes, I now realize I asked basically the same question 2 months ago. But now I'm only looking for 100 WHP 
1Liter bike engine.
Do you plan on driving on the street, or will this be a track toy?
Datsun L20B or Nissan SR
A Mazda BP would be another alternative
All will require typical engine swap foibles so they will cheap up front, but more expensive downstream as you figure out how to get it all stuffed in the car and working.
Miata engine

You can get more powerful vintage race motors, but you'd have to pay more. Mini Mania also sells a couple of drop-in 1380s for more money, but they wouldn't be vintage legal.
Mazda B6ZE, the 1.6L out of the '90-'93 Miata. Slightly smaller than the BP and available for dirt cheap.

I have a bugeye, I have been thinking about getting another spridget to do this for awhile.
what do you want the car to do?
I really like the bike engine idea, but I did just buy a B6ZE for my MGB.
I think a route that would probably be much more vintage legal is to get the stock motor and spin it to 10,000 RPM. Have no idea how to do that though, or the costs involved.
LS swap should triple that output goal easily...
I always thought the DOHC 1.3 Swift GT engine would be a perfect fit in a spridget.
Really does depend on what you want to do with it. I'd go the 1275 route as it only deals directly with the engine. All other options include modification to other components.
Think vintage legal and 100hp is contradictory terms. Anything done to a Midget engine to reach 100hp throws it out of vintage and going with an engine swap to meet or exceed 100hp throws it out of vintage.
There was a company in England that modified BMW (I think) motorcycle DOHC heads for a 1275 Midget engine use but very costly. Could swap in another engine already 100hp for cheaper.
A little different....4AGE
And yes, 100 HP out of a 1275 is easy peasy. I was over that with a SCCA HP Limited Prep engine (required to use a minimally ported head).
As far as vintage legal, I'm sure they are getting waaay over 100HP with a 1275 - OS valves, huge over bore, side draft webber, etc
Audi 4.2 V8. 18" long, probably the most power that will fit in a Morris Minor.

I was going to say this plus forced induction for even more fun and headaches.
Thanks for the responses. Just got back from looking at the car. Pretty decent shape, but it will need floors which I guess is standard for these even if they are sunbelt cars (it's been sitting in a shed in Ontario for a while not too). And the guy wants $950 CAD. That sounds high for the shape it's in as I can get a complete car with the floors done for about double that.
My kingdom for a 1500 pound car with at least 100 HP at the wheels for $10K CAD!

Nope. There are plenty of vintage racers running more hp than that on 1275 motors. What's "legal" depends on the racing organization, but few, if any, restrict what you can do with the motor beyond displacement. Vintage racing ain't what it used to be. Engine swaps aren't allowed, of course, except many organizations allow 1275's in Bugeyes now, which wasn't the case a few years ago.
In my '62 Sprite Mk II I've got a mildly built 1275 w/ a Megadyne 266 cam, header and side draft Weber that's probably making about 100 and it's fun. It feels a bit faster than my NA Miata w/ an intake/header/exhaust.
I race a car powered by a stock gen II 1340 Hayabusa. It's completely nuts.
I'd offer that the fundamental vibe of the car is perfect w/ a good 1275 B-L "A" engine.

Sounds like you need a mildly race-prepped CRX.
I have personally done a Fiat 124 1600 DOHC It was a lot of fun.
I have seen several rotaries and they seen to fit the best in the engine compartment. Exhaust is another issue. Wicked fast on the slalom course.

1300cc from a swift with a Tracker gearbox is a sweet package that stays away from major fabrication. http://www.ado13.com/dohczuke/dohc.htm
I like the Miata idea myself shifter might end up at the rear bulkhead.
The GM 3.4 V6 has been done.
Here is a Zetec engine out of the focus

The rear axle needs to be swapped for any swap.
None of these are what I would call "engine swaps" so much as full make-overs. I got the Fiat engine into the Midget engine compartment easy enough, but had to fabricate a full transmission tunnel and never did get most gauges working. (I was 18 at the time and pretty green and broke when it came to car stuff)
Surprised no one has mentioned 22re. The late series ('85+) was 117hp and 140tq. Simple, cheap, lots of aftermarket. Runs on carbs. Side drafts work with the engine design, though the uninformed will say it doesn't... (They need to learn more)
Not the easiest, but probably the most unlikely way... There use to be an old-timer up in Vt, that had a midget with a flathead Ford with a supercharger. It all blew thru a 2" SU mounted on the firewall. The intake track must have been 8 feet long on this thing. He use to show up at the big MG show at the museum in Westminster.
