Got a semi-built engine pushing 15+ psi with 2560, the same old recipe.

So freaking tired at sitting with 4,5k rpm in 140kmph.
Somehow a 3,636 is easier to get from this forums than fining on "locally" in the EU but I could order a 3.30 mfactory gearset.

​​​​​​at this time I got a 4.3 and I suppose a 3,636 would be perfect but will i hate myself (more than i already do) if I get the 3,30?

This summer I will finally max out my turbo and get a tune from a reputable tuner.

Installment is not an issue.

Thanks bros.

My car does 99% street drive

 

6 speed? I think the 3.3 would be fine with your setup if you are just mostly driving around on the highway.

With a 5 speed and a 3.3 your hitting almost 80 in second gear and sitting at 2350 rpms @ 100kph in 5th

3.3 is always my vote for a street car with decent power.

FYI I killed a NA8 5 speed with a 2560 totally maxed out. If you don't have a 6 speed you should budget for one.
