5spd VS S Ecotec
Hey guys, I'm interested in buying some new diff gears but wasnt too sure whether to go 3.45's or 3.7's.

Would love to hear some opinions/recommendations.
Thanks!

I put 3.45s in my vt with t5 behind it and at 100km/h it sits bout 2150-2200rpm better acceleration than standard 3.08s. Was gonna go 3.7s but i drive 100kms a day on freeway so didn't want it revin too high...

What size are the tyres?

This has a large effect on the overall gearing.

vs 5litre
go 3.9s with a 5 speed, this is what i have in my auto and they are awesome. #### economy, if you want economy go buy a smart car or hybrid. make sure you get new 3.9's not second hand 3.89's out of the nissans cause they are noisy even when new, alot of guys on ebay sell these cheap and advertise them as 3.9's.
