That's the first thing I did when I found this car on Craigslist. If the control arms were bad, I would have deem these car as junk. In short, they are pretty rock solid. As for pulling the carpets out, that's going to be a springtime project, due to the fact that it's cold here in the mid-west. The plan that I have in store for the floor plans are to use is William S. Hirsch Miracle Paint for the rust. It works like POR-15 except the prep work is not as finicky.

I pissed with all kinds of mods for better fuel economy with my first Metro and broke the 60 MPG mark quite often. Aeromods work well but the best mpg mods are....... A HEALTHY engine with XFi or 3Tech economy cam (plus gear for 3tech) An XFi transmission or upgrading to P155/80R13 tires (similar results) Rolling Resistance - Tires to max, good bearings, cleaned and lubed brakes, etc Adjust your driving habits to gain even more. |

So what you are saying is that a base model G10 engine can achieve the same fuel economy as as XFI, provide that you have all things mentioned. I also keep encountering suggestions for a 3Tech cylinder head. The question is, how does their cylinder head provide any more MPG benefit over a stock head? |

They're pretty much identical. Going from 12" to 13" tires is the same difference as the steps between the four different gear ratios available. 89-94 Base and LSI models came with 12" wheels and the 4.11 gears, XFI came with 12" and 3.79. If you just put the 13" wheels on your base or LSI, you'll end up with the same result as swapping in an XFI tranny. Get the speedometer drive gear off the 95-01 car you get the wheels from, that way your speedo will be accurate. A base model with an economy cam and sprocket and 155-13 tires is, for all intents and purposes, an XFI. It will be capable of 50 mpg when driven reasonably. I'm not sure how much actual difference the 3Tech head would make. I think he smooths out the ports, removes the swirl tubes, and mills the head a bit. The key is, his cam and sprocket are a very important key part. Your head needs redone anyway, why not send it to the master? He's going to do a top notch job on it, covering all bases.

back to your original list, if you were going to use the afm gauge you wouldn't need a 4 wire o2 sensor. the afm gauge comes with a 6 wire o2 sensor and it has an electronic output for a simulated narrow band signal that you route to the ecu. that way, you have the dependable display of the afm and a solid electrical signal to the ecm. the 6 wire o2 sensor is a heated type and it's considerably more stable than a rigged up 4 wire o2 sensor. |

You know what's interesting is that there is another gentleman who goes by the name, Geo Jeff who's been saying the same thing as you guys. He also states that in comparison, the XFI has a de-tuned motor, whereas a stock Metro with a remanufactured engine, in addition to the added suggestions would achieve more hp & have the same gas mileage as an XFI. In fact, I think that he may even be a member of this forum. http://www.youtube.com/watch?v=sNV8N62eHuM Edited by Davo53209, Feb 3 2013, 06:58 PM.

What about decking the block to the max (for higher compression) and running premium fuel? Any gains in fuel efficiency? |

you might get 1 mpg gain.....but your premium gas will run 30 cents more per gallon......so your actual operating cost will be more. |

It's looking like I'm going to have to revise my list. The best part about it is that everyone here has saved me a lot of time and trouble from hair pulley trial & error. Most especially, you've most likely have saved me a lot of money. I'm still looking for more suggestions, so if anymore people would like to help me whittle down my original list, then please do. Also, I'm trying to determine how increasing the hp of an engine can increase MPG. That was something else that I forgot to add to my list. |
