multi throttle body geo 1.0 liter

I was about to put a bunch of quality advice down on the slim chance he isn't trolling, but upon further reflection, I think this case is futile.

If you have the skill make yourself a bigger intake manifold that can handle one big throttle body (one off a north star v8) and K&N style filter mounted to the throttle body. Just need a vacuum line for your map sensor. Another route would be change out your exhaust to something that lets your motor breath a little better, upsize about a 1/4 to 1/2 inch. Exhaust would be easier; I do not know your skill level with fabrication. Fastest thing that you can try would be; take the entire air box off and just mount a filter to your throttle body (Atv or motorcycle size, foam or K&N style). I did that to my Eldorado and felt like it had a nice increase in power, sounded nice too accelerating.

trolling towing ... sounds about the same
some people do not know , what they do not know .
and
you can not polish a turd

imho the OP needs a large bucket of TP ( turd polish ) for his un-brilliant idea that many more skilled people have already shown will never work

If you want to know about Geo Metro 1 liters, go to TeamSwift.com. Thats a group of people who specialize in all things Suzuki Swift, which is where the geo comes from, essentially the same motor since 1982, with updates over the years, from carbed to tbi to efi, from dist to crank triggers for ignition. Turbo or non turbo, engine swaps, upgrades and mods. Bike carbs are popular where smog inspections aren't an issue if you want hp, but sacrifice daily driving ease. Look em up

Itbs are sure to remove any chance of low range torque that you might have had using that triple knocker, unless hou do some sonic tuning for helmholtz (SP) frequency and specifically design an intake runner which takes advantage of it and keeps intake velocity high enough to retain a high volumetric efficiency.

You may not like the idea, but adding a turbo that will spool at 2.5-3k rpm and a dump injector on a MAP switch will get you a quick boost in power when you need it, cheaply and safely.

You don't need to be concerned with overloading your suspension if all you're doing is flat towing or dolly towing. If you're trailering at all, install overload springs and rear tires rated for more load than the 155R12 that came stock. You may consider something in the range of a 175/70R13, mostly having ratings of ~1300lbs at 35-40 psi, as I recall. Plenty for your application.

Get yourself an rv brake actuator that hooks into your trailer plug, and a brake controller. This will allow you to use the towed vehicle's brakes to assist stopping/slowing.

On the same note as intake tuning, the exhaust, particularly the manifold, is equally important. "Backpressure" requirements are wholly a myth. Tune a custom header to the rpm range that you require more torque for, then select a pipe diameter and length that will support proper fluid velocity and meet helmholtz frequencies for your engine configuration.

Do not convert to dualies. Your coefficient of friction will go down and you will jack-knife and die.

So far i have switched to silver stone rally tires which grip the road and stopped the pushing around while towing. Still not able pull steep hills at speed but I can slow down a bit and make it. I'm getting better than 25mpg. i also bought a tracker with a 1.6 8v and it gets the same gas mileage as the Geo towing so i know know I'm just short on power. I also put in some springs rubber snubs to stiffen up the springs to make it handle better hauling. The tires are a bit taller which is giving me great free way mileage empty and it makes my 3rd ad 4th gear more ideal for towing. Looking at the weight difference between the tracker which tows very well and its hp rating i can see that I could use just a few more hp maybe as much as 10 hp. its right on the edge. but as far as handling towing it works like a champ and the brakes have plenty to handle the load. I'm only pulling at 55/60 mph. my ford f-150 with a 300 six is 13 mpg or towing. If i wasn't such a metro die hard the tracker is a great tow rig.

I'm laughing at these posts most of you made about how it wont work etc etc and it works so well. keep up the good positive work guys, I love how most people confuse the thought of facts with there opinions and what they think will happen. I also just made a speed run in my metro from Missulau montana to spokane washington with 3 people luggage and it was so have in the rear i had to flare the rear fender bead a bit so it would rub on the bumps in the ****ty road. any how we drove as fast as we could which was 75 barely and up the pass through the mountains in third gear wide open and I got 46/48 mpg. this new motor and raised compression and the signin grooves etc are really starting to come into play and i am able to get way out there with the timing. still playing with it. I didnt even get to use my clutch engine kill switch but the hand throttle came in handy.

Be sure to let us know how long the transmission lasts...
