i have a 1990 mustang and i'm about to swap into it a 2.3t from a 1985 t-bird. My questions are:
1. What is the stock boost for the car?
2. What vaccum line do i need to t-off for a aftermarket bov?
3. How in the hell do i put a boost controller on this internal waste
gate turbo?

Any help would be greatly appreciated!

(If you say 'search,' i already have and couldn't find my answers. )

Stock boost for automatic was 10psi and for manual I think it was 15.
Vacuum line for the BOV, I hooked it up to an unused port on the vacuum T on the firewall. Also seen it hooked up to the boost controller, but I don't recommend it myself.
Boost controller should have directions, but you'll have the 3 way valve. Boost comes in from the compressor to the valve and is diverted to the boost controller and wastegate. The boost controller once set will allow say a 7psi wastegate. If you set the boost controller to bleed off 13 psi the waste will not start opening until close to 20 psi.

manual cars came with 12psi stock boost .

boost controller vacuum line needs to be connected to the intake before the throttle body.

bov vacuum line needs to be connected to intake after the throttle body.

i wouldn't 'Tee' off anything, but thats just me. its best to read boost for the wastegate right at the turbo compressor outlet. and for the BOV in the manifold.

boost controller goes on "vacuum line A" between the intake, and the internal wastegate actuators top port. and "vacuum line B" connects to the side port on the actuator.

A-has boost controller to alter boost signal to wastegate
B-is just to send an un-altered signal to wastegate

sorry if its confusing,here
