Has anyone done the cam swap but still have the 12" tires? What will that do for your mpg? Thanks, Craig

I doubt that anybody still has the 12's
I installed 13's with the same diameter overall. The MPG should be the same.

Mine is an Lsi. Just wondering how much it would change the FE if I just did the cam swap and not the tires or trans. Thanks

You will gain a little.
I did not change the tranny in mine, just the final gear. I had to mill 15thou on the face and that was it. I have been saving fuel since then. Quite important these days as fuel prices in Quebec have skyrocketed to 1.45 a liter or about $6.00 a gallon.
Of course the gvnmt. is mighty happy. Taxes are on the total price not by liter.

Does anyone know if there's an "economy cam" like this available for the 4 cylinder engine - since I'm working on mine? It's the 1.3 liter engine in a '99 Swift.
Thanks,
Bill

Good question. I wonder if the 3 cyl and 4 cyl SOHC used the same cam profile. If so, you could get an economy grind done from a 4 cyl cam.

I can tell you will probably know: Mike at 3-Tech performance: http://www.teamswift.net/3tech/

Well, it looks like this question is definitely for real, now.... The mechanic had my car up & running and was about to call me to come get it when it died. Guess some oil passages got blocked somehow, and 3 cam bearings went out. He thinks the machine shop did it during the valve job. Need to replace the cam and some other stuff now. - dammit -

so - e-mailing "3tech" now...
