DIY 03 G35 Coupe 5AT to 07 G35S 5AT differential swap

Huum, I’ve been trying to figure out why everyone wants to do this swap. With the assumption that eventually everyone wants to go FI. Why would you want shorter gears? Me personally, longer gears means longer boost! Now if one were to go SC and was track racing I could understand the use of the shorter gears (faster corner exits.) For most of us (including me) most of our crafty work to our cars is being displayed on the local highways and roads (also YouTube) which means long gears would be perfect….
So why does everyone want short gears again?
Sorry didn't mean to thread jack... Nice write up by the way. I just want to understand why members are doing this mod.

Not all of us want the headaches of a boosted VQ motor nor be need all that power. I've had more powerful cars in the past and I've come to learn lower 14-second and 13-second cars are plenty fast to be enjoyable both on the street and in racing.

And about the topic I completely agree with Tollboothwilley. A higher FD (shorter gears) is all good as long as you have traction !

taller gear FI, shorter gears NA... for FI its not just traction that is an issue though - they run out of gear real fast (some cant even really use first gear with too shot a fd)....

a 3.7 may be good enough for traction with right tires FI, but most if not all go 3.9 or 4.08 FI or not. I only know of auto Gs and Zs getting the 3.7fd.
To be honest I didn't know there was a 3.7 available until maybe a 2-3yrs months ago. I only knew 3.3, 3.5, 3.9 and now recently 4.08. OCG35 has the 3.7 and at the time Rookie had it in his TT FX which he let me take down the 1/4 mile. I think he has the 3.9 now.

IMO, a centrifugal blower is a far better overall performance setup, though it might be slower.
- The power is more linear and controllable. Boost doesn't come on like a sledgehammer and risk unbalancing the car. It's just a more tractable power band.
- It's far easier to tune because power doesn't ramp up extremely fast.
- It's generally just easier on the motor.
- Easy to install
- Generally easy to fix and bypass, if needed
