as above i got the 918 blade engine and running the 3.62 diff is this the right one
only asking because it used to have the pinto engine in it

depend what you want to do with it

3.62 is spot on for a 918 blade, should give approx 125 at the limiter (dependent on tyre size etc)

Dont worry about the diff, get a proper rev counter and start giving it some beans !!

i now m8 i sorting it just traying to sort out if dunk will fit my and my will fit dunks m8 i been looking fo a cheap 1 just to put me on for now
