"MPGiata" modding thread: aiming for 50 MPG with a 1990 Miata. Update: success, 55 MPG!

Water injection on gasoline cars does not increase FE without other mods.

It is a very good detonation inhibitor (or retarder) so you can put more boost or have a higher compression ratio or run lower octane gas. Or increase timing advance.

[ProDigit]

Water injection cools cylinders, which allow for greater turbo boosts.

You NEED this.

This is a super rare 1991 Suzuki Swift GTI with the 1.3L DOHC. These were not production cars in the states.
The car comes with the white wheels picture
35mpg

The Suzuki Cultus is a supermini car produced by the Japanese manufacturer Suzuki from 1983 to 2003, and it is now a rebadged Suzuki Celerio in Pakistan since 2017. It was first presented at the 25th Tokyo Motor Show, formally introduced to Japan in 1983 and ultimately sold in seven countries across three generations and marketed worldwide as the Suzuki Swift. An alliance formed in 1981 between GM and Suzuki (and Isuzu) allowed GM to market the Cultus as a captive import internationally under more than a dozen nameplates including the Geo Metro, Chevrolet Sprint, Pontiac Firefly and Holden Barina.[1] It was also known as the M-car within GM.

The higher powered Swift GTi had an improved G13B engine which featured hollow camshafts, stronger web casting on the engine block, a better flowing intake manifold (the prior generation intake manifold had its shape compromised to fit into the engine bay), and its ECU now had electronic control over ignition timing. It now put out 101 PS (74 kW; 100 hp) of power. The GTi also featured all wheel disc brakes. Japanese GTi's have a much higher compression ratio (11.5:1) and accordingly more power at 115 PS (85 kW; 113 hp).

Asking $3000 OBO

Ha! That's a funny ad - there were no Swift convertbles! Maybe they put the Swift 1.3L into a Metro and forgot to tell us.


I actually already have one of those tucked away in the garage...


Another car for MetroMPG: convertible 1991 Pontiac Firefly (Geo Metro)



At some point, I'll have to decide which one I'm going to keep - the Miata or that Firefly convertible!

[19bonestock88]

I’d keep the MPGiata and sell the convertible Firefly... it’s probably much more fun to drive...

[Lemmy]

Did you guys ever get the Suzuki Cappucino over there?

[MetroMPG]

Not when new. We can import 15 year-old ones to Canada, though. I know there are some in the country, but I've never seen one in person.


Neat machines!

[19bonestock88]

The early ones are just old enough to import to the US...

Consider a lift-off top that has a lot of plan taper and integral boat tail. Bubble-top coupe it. Like this without the wing.

[MetroMPG]

That'd easily vault the car past 50 mpg at 50 mph...

But, nope! Not gonna happen.

The main reason I got the car is for its lack of roof.
