Time to chime in...... I went with the unisteer manual rack. Came with the steering linkage and tie rod ends.
I need to get caught up with what this little project consists of. So you have a 4.6 2v with what looks like maybe an on3 turbo kit?
I wish I would of stumbled on this sooner as this is not a simple bolt on deal. I have a CG fab kit and it involved quite a few alterations.
#1.... I saw someone above mentioned getting a boost controller to keep boost levels down... that is not how a boost controller works. You cannot lower boost more that what the minimum spring pressure is on the waste-gate. Is this a stock short block? What is the waste gate spring currently? I wouldn't run more than 8psi on the stock engine personally.
Here is the basic diagram to hook up your waste-gate.. Run a line from the turbo compressor to the bottom port on the gate. As for the BOV you can run a t-source anywhere off the plenum.
Shoot me a pm for any questions you have I would be glad to help out.
The manual rack and brakes will clear a ton of room up. I also got rid of the ac and expansion tank style coolant system and did a recovery style.
