Hi Guys,

I was looking through some of the posts on Steve and Rob's site for info on installing a Profec B but I didn't see anything on non-seq applications so I thought I'd ask you all. This might be a good topic to post in the FAQ's as no one has anything on this for non-seq turbos.

So, I've got my turbos non-sequential and it's a full non-seq conversion.

Is there anything special I need to do in addition to the instructions below ?? ..do I just leave the pre-control actuator as is?

1) What do I do (if anything) with the two solenoids up by the upper intake manifold... the pre-control and the wastegate solenoids ?? There is some debate about where to splice in the Profec B black box.. on the pre-control, the wastegate or both...is it different for non-seq's???

How about a "t" at the pre-control and wastegate solenoids and then to the black box? or as someone else suggested..swap the vac lines from the pre-control solenoid and put it on the wastegate solenoid and then from there to the black box??

2) Also, I have one of the remote low-hi boost things that goes on the steering wheel.. do I just plug in the sensor thing to the back of the Profec B and stick it somewhere close to the remote switch??

3) How do I set the dip switchs at the back of the Profec B for non-sequential turbos ???????

Thanks for any help you can offer,

Rgds,

PRofec B installation:
Remove air box and intake piping so you can access the waste gate.
remove the 4 inch piece of hose going from the turbo to the wastegate. This tubing contains the pill which you dont need now.
mount the stepper motor or little black box somewhere around the headlight under the hood.
run a piece of hose from the turbo to the "IN" on the black box, then from the "OUT" to the waste gate. It just acts as a bridge between the two. Then reinstall the air box and intake hoses.
run the power cable coming from the black box inside the car near the drivers side kick panel. I took it through the steering wheel boot or follow through where your boost gauge hose goes into the cockpit.
Mount the the Profec B somewhere where you can access the dials on it. I velcrowed it to the kick panel to the left of the clutch.
Now take the vaccum tubing for the boost gauge and cut it near the back of the Profec and add a T connector. Take a small piece of tubing and go from the T connector to the back of the Profec B.
Find where you want to add the power to the Profec B and there ya have it. Make sure to keep the settings all the way down at first. That would be the LOW setting. then play with it and have fun.

Hope this helps. Any questions email me at jason1@infinet.com.

You may want to add to step 2 and disconnect factory bleeder solenoid hose from the second nipple on the wastegate actuator. Plug this nipple on the actuator.

Also add that you need do nothing to the pre-control actuator. Many people have y'd the profec to both the pre-control and wastegate, not good.

I am wondering what kind of installation variations you all have on your
3rd gen with a Profec B installed.....

I am currently taking out the small 3" hose (contains the pill) that goes
from the turbo to the wastegate..... and putting the profec B inline
there.... I am also taking off the bottom line of the wastegate and
capping both ends....

I am noticing that boost seems to come on much slower than the manual
bleed valve I had hooked up....

Is this the only way to do it?? what happends if you don't remove the
bottom line off the wastegate?


I have it going from the actuator to the IN on the Profec and then from the OUT on the Profec to the Wastegate. Also I have capped the other side of that wastegate which allows the ECU to control boost. With this setup and the profec OFF you should get about 7psi of boost. Using the Sharp/Mild Button, that will allow you to control how fast boost comes on. Farther to the SHARP side and the quicker the response, but the less stable the boost is. More to the Mild and slower the response but more stable boost. I leave mine a few clicks off Sharp, which seems to work well for me.

BUMP !

Come on guys..quit looking and post something !

Run a line from one of your compressor outlet nipples to the IN on the profec. Cap the other compressor outlet nipple. Run the OUT on the profec to one of the nipples on the wastegate pot. Cap the other wastegate pot nipple. I never touched a solenoid. Enjoy.

Thanks guys.

RIkiki.. I couldn't find anything on the Profec B install with non-seq's ...hence the post.

Thanks again... anyone else done this ???

Basically you're running a single turbo with an internal wastegate. Unless you want your power FC or something to control boost, you have no need for boost control solenoids. The Greddy box IS your new solenoid. www.scuderiaciriani.com has it layed out, but that looks like where you got your info already. Its a very simple setup -2 hoses to contorl boost, thus the beauty of non seq.
