Im planning on maxing out this turbo in the future. what size exhaust will i need?

Wow, this question is way too open ended. For starters, What are your power goals? Will this be a drag or street setup? DD? Supporting mods? T3 or T4?

For a street setup, I would run a .68 or .70 T4 AR or a .81 ish T3. The 1JZ seems to spool those sizes very well.

0.68 Ar should be fine, Some guy in the other forum made 665hp at 28 psi, with this turbo, i'm planning on running it too in the future.

I should rephrase the question. Will a 3" exhaust be enough for this turbo at its max w/ a .68 housing? I want to do the exhaust only once.

You will be ok, My friend runs the same turbo & made 702hp at 32 psi on his evo 2, He has run a best of 10.24 at 145 mph...:aigo:
