In reply to captdownshift:
Already thought about that one before all this mpg stuff. It is too long. The SHO is pushing it.
I'm just going to ramble a bit because I've never done this, but, what about a Mazda F2 and no T? It's still decently torquey and I want to believe with some lean tuning (that a turbo engine probably isn't going to like as much) there should be some great mileages available in the thing. If you really want mileage more than hoonage then it might be a great thing to consider.
Does it have to be RWD? A friend of mine has an '85 GTI that we swapped a '91 GTI 2.0L 16v into (using the stock '85 cis-e fuel injection). He's averaging 37mpg mixed driving in a car that will run high 14s in the 1/4. With H&R springs and Bilsteins on it, it's a fun car.
Problem is that I already have the Starlet. My wife isn't so keen on buying more projects
A K-Swap, D-swap, B-Swap, etc. in your Insight is going to result in way better mileage than anything you can stuff in the Starlet.
Instead of sacrificing everything only to fall short of your 36mpg goal in the Starlet, why not do a simple swap, easily exceed 40mpg, and have plenty of power to spare?
the sportage i just scrapped managed 38mpg highway with stock gearing 5 speed and 235/75/15s. the 2.0 out of one of those would be fun if you can find away to make power with it

Boost the snot out of it. That's a 500whp-capable unopened motor.

it was reliable as hell, it just got rusty as E36 M3. i know everytime i borrowed it from my dad it went 4 wheeling.
It would sound like ass but the GM 60 degree in the 3.5L trim comes to mind... I have spent too much time looking at MGs
The large-bore 3.5 and 3.9s with variable cam timing are actually pretty damn sweet considering the E36 M3boxes they are descended from. I have a 5spd and flywheel out of a 3.4 camaro that is yours for the price of shipping if you get serious on that angle.
I vote for the TDI also. If I can hit 50 mpg in a golf why can't you ? A tune and injectors and you'll be hitting 400 lbs of torque.
Festiva engine is tuned more for mpg and will bolt to your Miata transmission.
Metro 3-cylinder can be rwd with a Samurai transmission, with or without turbo, and so can it's 4-cylinder DOHC hot cousin from a Sprint GT.
In a Starlet though I would want a 2TC/3TC with some sort of EFI. Or the TDI since the Acme adapter should be able to work with the Starlet transmission with a pickup bell housing.

You fowl temptress you!
TDI and metro would work find but the Metro motor really doesn't meet my power interests. The TDI does but that is at least twice the cost of most of my other options and still needs custom (non factory) parts.
my 91 volvo wagon is my daily driver...
I know you said no 4AGEs.... but
The nose on my E7 Corolla is about as tall/blunt as your KP61... and I managed 33 mpg @ 70 mph... with my 165 hp smallport 4AGE...
A well built 140hp 4AGE with a well thought out management system can likely run AFRs around 16+ on the highway... especially with a deshrouded head, and a decent forged piston. If you tune is set for lean @ your highway plots on your fuel map then mid to upper 30s should be no problem
another option... properly done blacktop swap usually manage about 35 on the highway....

this has piqued my interest for a 4 cyl swap of my own. this motor even has a rear sump oil pan it looks like from kia parts diagrams?

Yup it does. It's a very good motor. The original Mazda variant (more aggressive cams) is very popular down under for making outrageous power.
It also bolts to the same transmissions an F2/F2T will. I know of a couple in Miatas bolted to a Miata 6spd.
Is there a reason that those F series motors can't bolt to a miata 5 speed? I already have one of those.
Tuned TDi with one of the numerous adapters to a toyota W tranny or to the samuri tranny. As long as its not too tall. FE3 from a kia sportage wouldnt be a bad choice either, but meh. Just requires putting a B2200 bell housing onto a miata tranny or if you arent using the miata PPF using an FC N/A RX7 tranny for the lowest ratio 5th gear would maybe help mileage. The other option would be B2600 bellhousing on an RX7 turbo tranny.

Fowl Temptress you say? To the google!
Is this going to turn into a furry thread?? (Funny joke though)
just realized you were looking for an engine and not a car... nvm

The 1.3 SOHC 16V motor (98-01 Swift/Metro) does. It's capable of ridiculous fuel economy, and can make decent power, too.
Ben, can the f2t be put in an miata? I do have a b2200 tranny.
