im turboing my z6 currently. The motor will be setup mostly stock with arp headstuds, new y8 headgasket, stage 2 clutch with lightened flywheel, and new timing belt and water pump. I will be using an hf manifold with hf/t3 adapter plate. I am just wondering what would be the best t3 turbo to use. I would like to be in the high 13's with this build after a good tune so i just would like to gather some information on the best t3 turbo i should get. The best bang for my buck turbo. Thanks

 

.48/.60
or
.42/.48

in that order

 

I agree, i ran the same one on my z6 about a year ago, boost comes in real quick, its hard and goes all the way to redline, perfect for if your not going over kill and trying to get 5000whp out of the thing, very fun turbo, look into a company on ebay called down2turbo, they sell REAL garrett remans, and they are awesome, that side turbo goes for 350 with a internal wastegate set at 8 psi, i ran 10 psi on mine and my z6 held it just fine

 

and just a ballpark figure, what would a ef with a z6 and a t3 .42/.60 run on around 8psi?

 

probably for sure maybe in between 14.9 and 15.2 at fastest

 

u serious?? I was thinking more like low 13s?

 

i have seen stock z6 motors in ef's run 15.5

 

t3 60-1

oh sorry i forgot you said budget build, i would go with the turbo jago referenced

 

Newb question:

So which of these would be the .48/.60?
