Doing emissions removal on a 87 turbo and just wondering what solenoid needs to be kept....if any at all..? I thought the boost pressure or twin scroll solenoid needed to be kept but is that only on 89-91? Blah, im tired and my post may be a little confused, so excuse me for that. :P

bump.

Also, the line that comes off the intake to the solenoid rack....I assume can be capped off, correct?

the twin scroll solenoid should be kept for s4 turbos. there's not much point in removing it, it's there to improve low end torque. the s5 turbos have a different design that eliminates the twin scroll solenoid and actuator.

you need to keep the first one (black one not the one im holding) and as shown in the diagram you need to re route the vac hose to it

Yeah, ive read that many times...along with many other guides and it mentions nothing about the solenoid, while others say you should keep the twin scroll solenoid.

I got a BNR stage 2 and I got rid of the twin scroll actuator and removed the flap inside the exhaust manifold.
