#36 of 1864 Lemme try again
Aug 07, 1999 (12:54 am)
They scribbled my post so since I don't know what that means, I'll type it again.
A local speed shop which caters to...hmm...how shall I put this...young males with nothing better to do with $15K then spend it on a 10-year-old Civic Si...has parts for Geo Metros and Suzuki Swifts. But the throttle bodies and other parts they have fit only the Twin Cam 1.3L engine. Which means you must have a 1998 or newer 4-cylinder LSi Metro or a Swift to use them. I think a 1996-1999 Taurus SHO spolier would look good on the top of the hatchback. I also know 175/70R13 tires fit fine, and larger 185/65R14 tires should also fit if you get 14" wheels. My favorite (on the Tire Rack) is the Borbet Type M. I like the look of doubled 5-spokes. You can get a 2.5" exhaust made for your car with one of those Maxwell House sized chrome tips. You could get your car lowered 1-2" for a...um...dare I say "aggressive" stance?
Thanks Maureen, I feel more creative now.

Thank you very much, occupant1!
#38 of 1864 fan wouldn't turn on.

Help! My Geo Metro91 started to give me troubles. Can't use AC 'cause fan stopped working. (I leave in VA). Checked power on the connector that goes into the blower motor - nothing is there. Checked all fuses that could find - all are fine. For some reason there's no power on the motor when tirn the fan on.
Maybe some relay is dead. Any ideas will be welcomed. Thank you all in advance.

I found a interesting company that converts geo metro motors to aircraft motors for ultralights. They have a bunch of different HP version and claim 85+HP in their turbo model. They also offer parts for the do it your selfer.
Take a look. I'm interested in the headers right off the bat.
#40 of 1864 racing fuel?
Aug 11, 1999 (4:22 am)
would the 3cyl engine stay together if i put sunoco racing fuel in it? There's a station in my hometown (next to the racetrack) that sells it. It's quitea bargain at only $4/gallon.

I'm assuming that the Sunoco fuel is 105+ Octane correct? If you have a metro with a distributor you should be able to crank up the timing advancement to somewhere around 15-17 degrees BTDC.
Now one word of caution, if you do this make sure that you install spark plugs that are at least 1 heat range colder, preferably 2 heat ranges colder or you will melt the spark plugs rather quickly.
If your metro has distributorless ignition system I do not know the upper limit of advancement the computer will allow. I still would install colder spark plugs. Otherwise you are going to have a meltdown.
I would also add 4 ounces of Marvel Mystery Oil to the fuel tank before filling up with the racing fuel. This will help keep the valves cooler and better lubricated because the outer edges are going to get mighty toasty with that much advancement.
I mean what the heck, I'd try it.

That's pretty cool Inuvik! Now I can turn my little 3-cylinder chevy metro into an ultralight airplane! I'll just buy some wings and a propeller and a look out L.A. traffic, I'm going where no metro has gone before...
Seriously, though, the 85 hp turbo 3 cyl. sounds like a hot motor. You could probably pull at least 100 hp out of it in a metro with the right modifications (intake, exhaust, etc.). Now if only I had a few thousand dollars laying around to buy one. I think we could start our own suzuki-subcompact racing team pretty soon!

Just a word of caution!! Do NOT use any fuel in the 3-cyl. Metro engine higher that 87 octane. You'll end up with seriously burned valves and be looking at a replacement/rebuilt engine - I know from experience. I was fortunate to find a used Metro engine from Japan that I located over the internet & and have been very pleased with it! Other than this experience I've been extremely happy with my 94 Metro - and consistently get an overall 51 MPG.!!

I must beg to differ jr. Fuel octane is representative of it's ability to burn at combustion temperatures. The higher the octane number is, the more heat it takes to get the fuel to predetonate (spark knock) before ignition occurs.
In fact a higher octane fuel will run cooler in your combustion chamber because of it's resistance to predetonate. High octane fuels did not cause your valves to fail. The likely culprits were probably incorrect ignition timing, too hot of range of spark plug, or improper valvetrain lubrication. The most likely of all these are probably improper valvetrain lubrication.
The 3 cyl Suzuki engine is critical when cold to have good oil flow to the valvetrain. Running too thick of viscosity oil can damage the cam, valves rather quickly. Also dirty oil can cause lubrication restriction to cylinder #3 especially because of lower oil pressure due to dirty oil filters.
If your vehicle only requires regular unleaded fuel and has static timing like the 1985-1993 Metros the only thing that will happen when you run premium fuel is that you will spend 20 cents more a gallon for gas.
Now of course if you run premium fuels and start to tinker with ignition timing to take advantage of the higher octane, then most certainly you have to be careful about the edges of your valves overheating and burning.
I run 91 Octane in my Metro with 4 oz's of Marvel Mystery Oil per tank to keep the valves cooler. But the reason I do this is because although factory settings for ignition timing is 6 degrees BTDC (Before Top Dead Center) my timing is currently set at 12 degrees BTDC.
If I didn't change my timing I wouldn't need to do anything to run premium fuel day in day out. I have run with these settings for almost 50,000 miles with no problems. This Metro had 112,000 when I got it and now has a little over 160,000 with no breakdowns.
Sorry about your Metro engine going bad, but it wasn't due to higher octane fuels.

I was looking at MS Carpoint's website at the mileage figures for Metro's all the way back to 89. The 94 and older Metros have the high mileage 3 cylinder engines. There are 2 versions though- a 49hp I3 and a 55hp I3. The 49hp ONLY comes on XFI 2-doors. This engine is rated at 53/58mpg city/hwy. The 55hp engine that comes in all other models (non-XFI 2 doors and all 4 doors) is rated at 46/49mpg city/hwy. These figures are with the 5-speed. With the auto (only available with the 55-hp engine - can't get a 3 speed auto and the 49hp one) it's a lowly 36/39.
Hope this clears up some of the mileage debates. I'm looking for a metro myself for less than $2k. Anyone got one for me?
