i have a 2000 civic dx and i m interest of mfacotry 4.5 or maybe 4.7 final drive.
has anyone try mfactory final drive and how will it effect gas mileage ( i mostly drive in city)

 

You really should call MFactory. Good company.

 

Have you considered swapping in a Z6 or Y8 tranny first? It's A. a better transmission to start with (bigger bearings and geared shorter) and B. cheaper than buying a final drive.

If you do a lot of city driving and you can run in 5th in town a lot you probably wont loose much in the way of mileage. On the highway, yes you will.

That said MFactory makes really nice stuff.

 

yes. i have consider getting 96-00 ex tranny if i can find one with good condition and low mileage and this would be my best bet.
will the 4.5 final drive and ex tranny effect any gas mileage?

 

Maybe you missed this part.

 

right. i missed it.
