I think I want a blow job
Nothing extravagant, just 75ish on top of my 140. Cheap, simple easy. Snails or clams? I'm leaning to a hot side M45 just cuz it's cheap and easy. Oh, management is handled.

The only things I can think of which would get a naturally-aspirated Miata engine anywhere near 140 HP would more or less preclude the use of forced-induction.
We need to know a lot more about your engine.

I'll sell you this for $450.00:

1976 truck motor, 350, 4 bolt, wedge heads, Weind dual plane. Made 196hp/280tq in a 1974 Olds Cutlass. We discovered the camshaft was flat and only opened the valves about 1/4 the way. Installed a stock L31 truck cam and dynoed 248hp/310tq.
Quoted for truth. A "hot side" MP62 might get you close to 220whp, but its going to cost about $3000 bucks and up.

got nothing against turbos. I've just done a decent amount of development to get my exhaust where it is. That would mean starting over
I don't do double wide's

No offense, but what "development" on the exhaust have you done?
*shrug* That motor has around 500,000 miles on it. Looks it, doesn't it? You could probably weld the hood shut on a vehicle with that motor installed and never mess with it again. Cut an access hole for oil filling, of course.
Figured I'd offer.

Figured I'd offer.1 5/8 stepped to 1 3/4 long tube header, to 2.5
edit
I want to add 6-10# of boost on to what I have. If it's snails or clams I don't much care. I'd prefer clams because I know I can out flow it with the current exhaust.
