couple of turbo questions

  1. #1
    Have plans of going turbo in the near future. Just want to ask a few questions. With the MF2 controller where do you fit the 5th injector? it it just before the throtle body? What level of boost is safe for a standard engine? And how much more insurance did u guys have to pay out? Im 21 with 4 years no claims in april how badly will my wallet get hurt? Car is a VTS by the way.

    5th injector goes pointing towards the butterfly before TB, safe boost is up to 6psi, anything more without lowering compression will kill the pistons, even with low compression, std pistons will eventually fail as they are not designed for the heat. Insurance adds about an extra 3-500 a year on.
