As a yank with the 4.77 gears, I can answer some of the questions.
1) you're acceleration will significantly improve. The lower gearing makes the s2000 feel like a whole new car. I let people take mine for test drives, and I constantly hear "wow!".
2) the car is not any slower at 60mph. In fact, you get to 60mph much faster than the standard s2000 with the 4.1 gear. You will have to shift more, but its a small price to pay.

This will be purely dependent upon your shifting ability. The "gears" WILL help accelerate your car much quicker. Now, the big question is:
Will the advantage of the quicker acceleration be stripped away by the speed at which you shift. If you are a lightning fast shifter, then yes. If you shift slowly, then NO!

What's a Yellowbox? And could a mechanical incompetent really be able to "do it"?

Also, at motorway cruising speeds (85mph) what revs will the car be pulling in 6th and how does that compare with stock diff?

How does this change (to 4.77 diff) affect mpg?


Incidently, when it comes to improving the performance of the S2000, who are the best people to go to in the UK who really know what they are doing when it comes to this engine?

at 85mph, I am at 5300rpm

A Yellowbox is a little electronic box that modifies the speed signal. It just intercepts the speed signals from the gearbox, and adjusts them. You use it to correct the Speedo so it still reads correctly after you've changed the gearing.

No, it wouldn't be that accurate anyway. I'd need something that could accurately time between 1/4 and 1/2 second. This is what I estimate it takes me to do a fast shift. As seen in ItalianBuckwheat's thread, with 4.44's, he shaved off about .3 - .5 seconds 0-60. With 4.77's, you will need an extra shift. If it takes you 1/2 second to do one shift, then you might break even. If you can do the shift in less than 1/2 second, you might be ahead. However, if you are only talking about maxing out 2nd gear, you'll be faster to that road speed with 4.77's than with 4.44's. Once the 4.77 car shifts, the 4.44 will gain a bit until he has to shift. But we're talking fractions of a second here.
