Hello guys,

Just picked up my EFII today, I think it may have a 3.08 diff ratio? It only revs around 1800RPM at 100km/h and it feels a bit sluggish off the line.

I'm looking at changing to either 3.9 or 4.11 to give it a bit more go, will those gears fit in the diff housing with the 3.08?

Thanks guys.
