Hey guys. I am getting ready to install a Turbo kit I purchased and have researched pretty much everything. I already have the plumbing setup for the Oil feed & return lines on the engine and the Missing link installed. Everything else looks pretty simple with everything just bolting on. Only thing that has me a bit worried is the vacuum wiring and the fuel regulation. I want to make sure I have everything layed out the way I am going to install it so that there are no questions during installation. Can you let me know where the last couple of vacuum lines are hooked up to. This is what I have:

FMU - Back of Intake
Boost Gauge - T'ed to back of intake
BOV - T'ed to Brake booster line
External wastegate - ???
Manual Boost Controller - ???. This came with 2 pieces (A small box with 2 plugs and the main controller with 2 plugs and the turn knob)

On the SFMU, what do I have to adjust the pressure to on a Stock engine and what is the MAX boost I should run with Stock injectors.

Also, I don't like the way that the Outlet on my Turbo is facing up. Is there a problem if I unbolt it from the housing and make it face down to eliminate some of the intercooler piping. I'm running a FMIC and this would help me avoid having to run a U-bend from the outlet back down to the FMIC.

This is the setup that I am running:

T04E Turbo
3" Intercooler piping to fit my intercooler
Manual Boost Controller (I think whis goes between the Wastegate and it's vacuum source but not sure)
HKS SSQV BOV
35mm Wastegate (8PSI Spring Rate)
Vortech SFMU (Don't have any of the parts for this. Bought this used. Am I better off going with a NEW OBX 12:1 FMU I have?)
Walbro 255 Fuel Pump
Missing Link
Air/Fuel Gauge
Boost Gauge
EGT Pauge
Oil Pressure Gauge

Thanks in advance for any help you can give me.

The pic of the Turbocharger I bought shows a port on the compressor housing but the one I received does not have it. It's marked but looks to be filled in. Should I drill and tap it back in? If so, what type of fitting should I put in? Thanks for the help.

not sure about fitting but yeah ur supposed to drill and tap with a fitting. then clamp on a vac line from the fitting to your wastegate boost port clamp that too.. oh yeah and for clocking the turbo all you have to do is loosen up the bolts around the turbo then you can move the snail piece around then retighten bolts. facing down would be the best.
external or internal wastegate?

Great. No wonder I couldn't figure it out. I was missing that port. So once I have the vacuum line hooked up from the wastegate to the compressor housing I am just supposed to splice in the manual boost controller between the 2, right? Do I even need to use the second part of the Boost controller with the 3 ports if I am installing it in the Engine bay? Can't I just connect the vacuum hose from the wastegate to the back port of the controller and the front port of the controller to the compressor housing?

Here is what I have on mine:

Bottom port of MBC (Hallman) to wastegate

Side port T'd off to the BOV line (unless someone says otherwise, do not even bother tapping into your compressor housing, just run it to the BOV)

Hope this helps.

dont tap the turbo . you dont have to . run vac line from wastegate to boost controller to intake manifold .

Ideally you want all your vacuum lines to run out of your manifold. and ideally you do not want to Tee off any other lines. This will eliminate any "weak vacuum signals" any of the various parts may get, thus making them all perform at their best.

To TAP or NOT TO TAP the compressor housing. That is the question. It makes more sense for this to be the signal point to the Wastegate to tell it when to open and also use a shorter vacuum line. On the other hand, I know the manifold will show the actual boost pressure going into the engine. Will the boost pressure already be built up at the compressor housing to activate the wastegate if I tap into it there?

Do not bother tapping, as has been said. Here, humor me. Connect it like I said (WG to MBC to BOV line) and see how it is. If you run into any problems (which you won't) then change it up then. It will take you all of two seconds to connect the lines as I have said (just use some small zip ties on the lines as they may blow off) and you will find it to work fine. It works great for me at 23 PSI, so really, you won't have a problem.

Sweet. I'll do that then. So I should have 2 lines with that setup:

1)Wastegate to MBC
2)MBC to BOV - T'ed to Brake booster line

That means there will be 1 T on the brake booster line to hook up the line going to the BOV and another T hooked up to that line going to the MBC, right?

Hey guys. I'm down to the last few details with the installation. Hoping to have it done in the next 2 weeks. I really like the way it's turning out. I had to get another manifold because the one I originally bought had the flanges welded on wrong. The hood would not close. Do I have to use the Valve seat for the bottom of the Tial External wastegate? When I install it, the bottom of the wastegate no longer touches the mating surface of the manifold. If I do have to use it, should I still use the gasket between the Valve seat and the Manifold? I want to make sure I don't have a leak. TIA
