I copied this from McFly's post on genesiscoupe.com & wanted to say thanks to McFly for his insight.
For those going 2.0t w/high boost, 400+whp, gearing change will be needed, solution here
It's quite simple actually. But before we get to that. Here's how our gearing stacks up V6 vs. 2.0t:
V6 Gen Coupe, Long geariong for fuel economy, although good for boost
2.0t Gen Coupe, Short gearing to compensate for the lack of power, although bad for boost [at 400whp and above].
Now, here's how simple the solution is:
Swap out your rear end mechanicals (the part between the rear axle half shafts that attaches to the drive shaft coming from the tranmission) with the rear end mechanicals with a V6 owner (that may not be planing to going boost).
Benefits will go both ways:
The I4t will be able to run at 400whp without having to switch gears every few seconds, only to find another gear that has also run out. This will also allow you to put traction down and not just spin every time you get into full boost. It's a 3.54 Final drive rather than the 3.9 final drive. This will put you at an advantage.
The V6 will get better gearing, so that he can top out his 4th gear at the track instead of lazying through in 4th, and you will hit 0-60 in two gears at maximum RPMs as well instead of being halfway through your 2nd gear. It's a 3.9 Final drive rather than the 3.538 final drive. This will put YOU at an advantage.
Disclaimer: It has not been studied to find out whether the two will simply swap out, nice and easily. They probably will though. Nor, has it been found whether both rear ends have been made just as strong enough as the other. Can the rear end made for 220hp handle about 300whp, (about 360hp at the flywheel)??? Unknown. Can the rear end made for 220hp hand about 400whp (about 470hp at the flywheel)??? Also, unkown. Likely, it is only a simple final drive gear and pinion gear change. I can't see that it would be any different otherwise.
Also, the hmaservice.com diagrams and parts list don't seem to be any different.
As an option you can also simply change out the final drive of your own rear end, and go to whatever gear ratio you want. Here's more information on gearing, how a final drive change will be a great mod for a V6, examples of how it effects your top speed per gear, diagrams of the parts involved, parts lists, etc:
