ggzilla Posted March 13, 2014 Report Share Posted March 13, 2014 Check with S2000 daily driver track day racers before deciding that shorter gearing will reduce acceleration. Remember that redline is 9000 rpm vastly different from most engines swapped into a 510. By the way all transmissions have gear reduction in the transmission. Quote Link to comment
Stupid_fast Posted March 14, 2014 Report Share Posted March 14, 2014 AP1 has an additional 1.160:1 gear reduction in the box giving a effective final drive of 4.756 with 4.10 rear end. AP2 box has a 1.208 reduction with 0.763 6th gear turning ~3800rpm at 70mph with stock 4.10 and 235-50-16's. Quote Link to comment
ggzilla Posted March 15, 2014 Report Share Posted March 15, 2014 And the S2000 still accelerates faster with 4.6 gears. If you want less than the most performance, 4.3 or 4.1 are good compromise gears to increase fuel economy. Just depends on what the OP wants. Quote Link to comment
ggzilla Posted March 15, 2014 Report Share Posted March 15, 2014 You also need to factor in the tire size. First S2000 used a 50-series tire of 24.9" diameter. Example 510 fitted with 195/50R15 - 22.7" diameter 4.625 x 1.16 x 22.7 / 24.9 = 4.891 Or something like that .... Quote Link to comment
