Hello Everyone,
Ive been trying to do some digging on my Galant VR4 Evo trans. It has 3.909 Final drive gears in it. How well do these work for daily/weekend driving? I know the Evo 1-3 guys go from a 3.909 to a 3.545 to get more top speed from what Ive read. I currently have a TRE stage 3 w/ welded center(3.545) in my VR4. I'm tired of the welded center and have a 4 spider for it. Ive come to a point to where I am collecting parts for the Ludachris Resurrection rebuild and I figured the TRE would be better suited for it. I would take the Galant Evo trans and put it in my VR4 just need advice to keep the 3.909 gear or go to a 3.545 gear. Its going to stay with the 16g since its a street car and some autocross. And Advice would be helpful. Open to ideas and if anyone has any better info on the Galant Evo trans it would be much appreciated!

Evo guys wouldn't go with the 3.545 if they didn't need the top speed in 4th for drag racing (or highway fuel economy in rare cases). For a 16G car, the 3.909s are fantastic.

I should add that a Galant VR4 would be an absolute dog starting off with the long 1st gear, tall final drive and all that weight.

My Galant has a lot taken off of it so its lost a lot of weight. Im hoping my Galant Evo trans has a shorter first gear with the 3.909 gear to compensate for the weight. Thanks for the info! I just need to find a 3.909 pinion and gear to install now.

Just FYI as I had been looking at final drives this week:

1st Gear DSM 3.083:1 - 1st Gear Galant 2.571:1
5th Gear DSM 0.666:1 - 5th Gear Galant 0.617:1
Transfer DSM 1.090:1 - Transfer Galant 1.090:1
Rear DSM 3.545:1 - Rear Galant 3.909:1

I know you already had those but figured I would lay it out for anyone looking. Corresponding MPH speeds with a 25" tire are as shown below:

7500 RPM DSM 1st & DSM Final: 37 MPH
3000 RPM DSM 5th & DSM Final: 68 MPH

7500 RPM Galant 1st & Galant Final: 40 MPH
3000 RPM Galant 5th & Galant Final: 67 MPH

7500 RPM Galant 1st & DSM Final: 44 MPH
3000 RPM Galant 5th & DSM Final: 73 MPH

So to do what you were proposing your about 4 MPH taller in 1st at the shift and 6 MPH taller cruising on the highway. Doesn't seem that bad to me especially if you've got the power to swing it.
