Hello, and welcome
The 64/71/13 will make more power, but you might want a little more fuel to get the most out of it.
On the other hand the 62/71/13 has been used in 550hp builds, and will be a better daily driver.
With out more fuel/rpm I think the 62mm compressor is a better choice, but add some more fuel and/or rpm and you might like the 64mm
