I'll bet you could get awy with 89, or 91 octane, unless you're running lots of intial timing.

do you recemmend running with the 91 and retarding the timing some?

I would try the 89, then the 91, and see if you get any detonation as-is

Any updates?

read the previous posts, i just updated a week ago.

Any updates since then until now would be worthless.

I figured maybe you had tried lower octane gas and thus could report whether knock increased or not.

give me a few months to get good repeatable data.

Awesome, good to know that you're interested in good data, and not just spontaneous results.

BTW, thanks for the reports thus far.

Unfortunately, the great images of the tests Geo Hauler did after his upgrade have disappeared (see post #1).

I came back to this thread looking for information about how much the peak torque RPM may have shifted for an engine with the Economy/XFi cam.

It's obvious that there's more torque at lower RPM, but has the torque curve flattened? Or has the peak just shifted to a lower RPM? By how much?

Great - thanks, Mike.

I don't suppose you also have a BSFC graph for the g10, do you?

Someone linked me to one, which I'll post later on.

hello, any ideas how the results of these performance improvements might change on the newer / heavier 96-2001 model geo/ chevy metro?

davioh: my car's a '98 Firefly. So any of my comments about the XFi/economy cam in this thread & elsewhere apply to the '95 and newer cars.

Hey anybody know where i can get a new 3 cylinder engine for my geo metro? You see it was my first car i bought and some dirtbag screwed me over. I only got to drive it for a few days before i had to take it to Steves auto, and thats when he told me the bad news. I could really use the help. Thank you.

I believe you can still get the long block new engines through GM or Suzuki but their not cheap.

i've had great luck using the jdm import used engines that you can find on the internet.

japan has strict air care policies and they routinely replace 30 - 40 thousand mile engines with factory new engines over there. they ship the low mileage, used engines over here. you remove the intake and exhaust components from your hosed engine and swap them to the jdm unit and pop it back into the car.

i'd advise you to replace the front and rear crank seals, the cam seal, the distributor o-ring, and the valve cover seal before loading the jdm engine into the car. the importers usually hit the engines with a pressure washer and the long sea voyage inside a hot shipping container doesn't do the seals any good.

the jdm low mileage used engines are roughly a third of the cost of a new crate engine and in line with a good rebuild on your old mill (but a heck of a lot less work.) labor at a shop would kill the economics of rebuilding your engine and that makes the jdm import engine swap an even better deal.
