Keeping folks updated about 4.77 gears. Using 5w-30 Castrol GTX with Auto-Rx, good amount of freeway, add to that stop and go, around town, vtec up and down canyon a few times, 6th gear accel to over 100 a couple of times, etc., I got a little over 22mpg. Of course the Mugen ecu does lean things out a bit and helps with mileage, but I am pleased so far.

If I can have the 6th gear responsiveness on the fwy with over 22mpg, I am satisfied. I may not be able to get to the 30 and beyond mark in all fwy driving as I used to, but it would be nice to be in the mid 20s at least. We'll see.

 

I think you might've meant 22 mpG.

and why do you use 5 weight oil rather than 10?

if it snows in So. Cal, then I live in Siberia.

Just some info to keep in mind for those with and those who are thinking of getting the 4.77's.

The amount of torque and power you have on tap in turns if FAR greater after this mod. I have had a couple events where the HP/Torque was so much greater than I am used to tail has come out. Nothing that put me into a total spin but has been close.
