You really do not need a fmic, on a vf52 all your gonna do is give the car more lag. The stock tmic will.handle around 20.5 psi. I'm taking it you want the fmic for looks? With wrapping your DP correctly and a turbo blanket plus a heat shield with heat reflective tape on the under side of the shield, you'll be good to go if your concerned about heat soke. I'm making 450+ HP with a Blouch Dom 1.5xtr on a Process West top mount with everything wrapped up, heat and flow is not a problem. 16psi is nothing on that top mount, turn it up to 20 or so and be done for a while. Unless you have "BIG" plans for the car by all means go with your fmic.
