I posted this in response to Suprdave's thread in All Motor; figured some of you might benefit from it too.

3 Gear Set 3.077(1st), 1.600(3rd), 1.261(4th)

4 Gear Set 3.077(1st), 2.158(2nd), 1.650(3rd), 1.304(4th)

5 Gear Set 2.818(1st), 2.000(2nd), 1.471(3rd), 1.136(4th), 0.926(5th)

 

how do these compare to ats and stock?

You might want to compare gearsets vs gearsets. You can always add a final drive to any gearset as well.....

 

Looking at the ratios, the OS gearsets look like they may be for boosted applications.....

fyi -

ATS gear set:

3.077
2.105
1.652
1.308
1.033


Quaife gear set:

2.462
1.813
1.500
1.250
1.045


Kaaz gear set:

2.667
2.118
1.682
1.333
1.069


stock ITR gear set:

3.23
2.105
1.458
1.107
0.848

Dan, if you're referring to final drives, OS Giken also has a 4.929.

 

i was just refering to overall gearing, and how aggressive the os giken gear set is compared to a US ITR tran with jdm final drive, etc

 

Thanks for clarifying that for me
