Here is a pic I modified to show the Vac rack removal while keeping the PCV/Charcoal system and the FPR hot start system.

The solenoid was jusrt placed over there to give a better idea. You will have to get a line over to the orig spot or extend that wire on the harness.

Please tell me if anything looks wrong.

Thx

It all looks correct, but I'd question why you'd go to all the trouble to remove the rack rack when most of the pipes and hoses remain.

too late pretty much(Already hacked rack up). Also makes me understand WTF is under there since I had no idea previously with the rack in there.

Now is the Wastegate part correct?
Should I just Cap that extra part and It no longer needs to connect to the intake because I don't have the boost control solenoid?

NZConvertible

The wastegate part is correct, but unless you have an aftermarket boost controller to replace it, it's a bit of a step backwards.

Good pic through.

*a*jones*

would that pic be basically accurate on an N/A? does anyone have a pic similar to this for an N/A?

Well an NA is a little different because it can pull Vacuum from anywhere when a Turbo model has to pull Vacuum from before the turbo.

Also

Does anyone know if the direction of which way the solenoid is placed inline matters?

Is it a directional flow? If so which side should be the output for the FPR?

Thx.

Also Where can I tap a boost gauage? Does it have to be before or after the throttle plates.

I can remember right now but I believe thr front Vac nipples pull Vac from behind the plates and the rear nipples pull from before them.

You should be able to tee off a vac line from the bov line.

Well If I can tee off of the BOV line then it would be a pressure source after the throttle plates right?

Then I could probably use that Yellow capped spot right?

BTW NZ. I have a S4/S5 TII conversion so the twin scroll and S5 Boost solenoid are useless. I'll probably get a boost controller later after the car is up and running and the AFR's are set.

for the boost guage line it would be better to mount after the throttle body, that way you can measure vac and boost if you are using an aftermarket boost guage. i tapped mine into my boost pressure sensor line, teeing into the bov line would work as well.

I removed the ACV so I only have the single nipple on the UIM.

I also have a positive pressure only guage. I thought you may read boost spikes if you place it before the throttle plates.

Can anyone confirm if the top nipple on the front of the UIM is ok to use? Are any of them restricted where it might not read correctly/or quick enough?

NZConvertible

It does matter, as they're all 3-way solenoids. Look at the FSM schematic and arrange the solenoid and lines exactly as drawn.
It must be after the throttle plates or it won't see vacuum. Teeing into the pressure sensor or BOV line is easiest.
No, they're all different. On the rear (four nipples) the top three are fed from before the throttle and the bottom one is fed from before the throttle. On the front (three nipples) the top and bottom ones are fed from after the throttle and the middle one is fed from before the throttle.
Correct.
Being able to read vacuum is very useful. You should get a full-range gauge.
You'll see boost spike no matter where you put it.

*a*jones*

does anyone have a diagram like this for n/a

I used the picture from the FSM. Just get the NA version of the EFI manual.

THX NZ.

BTW this is a Jspec manifold and I only have 3 nipples on each side.

"Being able to read vacuum is very useful. You should get a full-range gauge."
I'd love to get a Full range but this conversion has cost me over 5k so far and I have Taxes and other things to pay for right now. I still have to get a TII hood too(CF FC3S.org).

OK,
So the stock PCV system uses a source before and after the throttle plates?

I'm just going to use the Top capped nipple for my Boost line for ease and to keep the BOV/Boost line a little more dedicated.

NZConvertible

In that case you'll be missing the one at the bottom on the rear that has vacuum for the dual throttle system on A-spec manifolds (but is not shown on the FSM vac diagrams). The ones you have will all be fed from before the throttle, for the primary and secondary injector air bleeds (small nipples) and oil nozzle spider (big nipple).
Yep, they both go to the purge control valve.

I was expecting a picture of a mumified cat... :P
