Evo X Turbo

Was planning on changing to a Garrett GTX3071R, but wanted to know what internals should I change just to be safe. Going for 400-450hp.

Torque kills the 4b11 bottom end, not HP. Keep it below 400tq and you'll be fine.

I ran the GTX3071R with stock internals for 5 years pushing ~400whp.
