if you remove one of the rings would it affect the life of the moter?

Hi, I have a white 1994 Geo Metro Xfi 2 dr 5spd. Ive had it since purchased new in 1994 in El Cajon California. Since I live in CA the sun beats down on all parts of the car all day, the Xfi logos have all but faded and I need replacement Xfi logos. Do you know where I can find new Xfi decals, thanks…Aaron

My Haynes repair manual(24075) says that Metros older than 1991 have the same lobe height than XFI models Is this True?

Is there any downside to having an XFI camshaft? A thousand bucks is quite bit to blow on an experiment like this.

Somebody said there was a greater risk of floating heads… is that true?

I just spoke to Delta Camshaft in Tacoma, Wa 253-572-2474

He he can sell you an xfi spec camshaft for any metro from 1989 to the most recent for $72. He said people report that the fuel economy increase i from 8 – 12 mpg.

He seemed very knowledgable.

Are you sure that’s right?

In less I made a mistake, my calculations say that in 4th, the engine rotates 3.464 (3.79 * 0.914) times per wheel rotation. And the wheel rotates .289 (1 / 3.464) times per engine rotation or 1.15 (.289 * 4) times for 4 engine rotations for the XFi transmission (3.79 gear ratio). Although the standard transmission (3.95 gear ratio) will rotate 1.11 times, which is pretty close to 1.15 times for the XFi. Would be pretty hard to tell the difference, especially without some trigonometry.
