You guys it all depends on what you want to do!
If you want a turbo for power, t3/t4 or mega power t04, however id never put a t4 on a ex.

And you see, 2800 full boost is NOT a good thing if you ask me. You will be running fullbost 100% of the time on the freeway, not the best thing in the world. But thats just me.
