YES ive searched, but i have yet to find a good thread where it shows the wastegate clearly and which pressure line to use.


ok so i was trying to install the forge MBC today and i knew where to install the inlet port from the turbo outlet. but the for the outlet port of the MBC, which pressure line do i take? i look down at the wastegate and there is one black line connected to a T-clamp. which line do i nipple? and which one do i connect? please help!!

also, once connected where the effer am i suppose to mount this sucker?

pix would be great! thx...

 

I did a search and found this for you....

Before installing this product, please be aware of your vehicle’s OEM boost control system and routing of vacuum/pressure lines. These intricate details are specific to each application and will effect the installation, mounting location, and tuning of this product on your vehicle.




Ref. 1 - This port on the UNOS manual boost controller is the inlet of the unit and needs to have a pressure source taken directly from the outlet of the turbo or from the intake manifold. We highly recommend that the source be taken from the outlet of the turbo or the intercooler piping as close to the turbo outlet as possible, but the intake manifold can be used if no turbo outlet source is available.
__________________________________________________ ________________

Ref. 2 - This port on the UNOS manual boost controller is the outlet of the unit and is to have a pressure line connected to the pressure reference on the wastegate actuator or external wastegate, depending upon the application.
__________________________________________________ ________________

Please DO NOT install the UNOS manual boost controller in the opposite orientation or with the inlet and outlet ports connected to the opposite sources from those that are recommended above. Doing so will prevent the unit from operating properly and may cause damage to the mechanical components of the engine or turbocharger if not installed correctly immediately.

If you have any specific questions or concerns about the installation of this product, please contact your preferred Forge Motorsport authorized dealer, your vehicle’s tuner, or you may contact us directly.

yea that's what i was just looking at. but i understand what needs to be done..but i was hoping to see if anyone had a pix of exactly which lines i needed to use. i should probably invest in an evo repair book. but in the mean time hoping i could get some help here.

 

Huh? The wastegate is the easiest part. You just do a line straight from the MBC to the wastegate nipple. The pressure source is the one where you have to decide whether to use the turbo outlet or the bov/intake line. You shouldn't retain any of the stock boost control lines. When you said "one black line connected to a T-clamp," did you mean a Tee fitting? That's part of the stock boost lines that have the restrictor pills. These get removed and are replaced by the new vaccuum lines.

 

Np maybe someone will chime in soon..

 

it's easy. one line form your boost controll go the wastegate and the other T-Off between your BOV and engine line.

 

ahh that makes more sense now...thx warrtalon always a good help. ok so the nipple of the wastegate actuator goes straight to the mbc, and the "t fitting" that was there is replaced by new vacuum lines?

anyone have a pic of the turbo outlet they used..just trying to get a clear picture, sorry for the noob questions, but this is the only way ill learn more.

thx again guys!

 

Maybe this will help you

Just look at the diagram. You don't reuse the stock boost lines. You also don't use any tee fittings if you use the turbo nipple as the pressure source. There's only a Tee fitting if you use the BOV/intake manifold line, which I don't do, but is fine to do if you want.

All you should have is one long hose going from the turbo outlet nipple to the MBC...and one long line going from the wastegate nipple to the MBC. As long as you match those lines with the proper fitting on the MBC, it will work. The turbo outlet nipple and wastegate nipple are only 3-4 inches from one another...

 

I bet this is the only time you get to talk about Nipples

 

sweet! ill try all this good stuff out tomorrow. anyone have any ideas on how to mount it? hahaha the mounting hardware isnt to sophistimacted dOH. but yea..where have others mounted the mbc and how?

 

With te IX's comming out theres alot of 1st time mods happening so here we go again. Nonetheless here are so helpfull hints:

1. Don't bend or break the wastegate actuator's 'L' nipple - it's weak
2. Make your lines as short as you can while still being able to reach for adjustment. Boost spikes are partly caused by too long of line from MBC to WG actuator.
3. Try not to use the BOV control line for MBC supply - it will make the BOV more prone to leak.
4. Never run a MBC w/o a guage and make sure your guage reads correctly
5. Minimal boost on our car is 14psi (as if you were to bypass a MBC and constantly send boost psi to the acuator) start here when tuning it, it might take alot of turning at first but gets touchy near the target.
6. Cap off the stock boost solonoid nipples (I just attached them together with a piece of hose) and keep the wire harness plugged in to it or your "Service Engine Soon" lite will illuminate.
7. For mounting, well, you will have to use your imagination and creativity for that - just don't throw it in there. I used your tax dollars to mount mine with aircraft grade hardware. I mounted it near the bottom of the fan - It's stealth, has very short lines, clear of high temperatures, but once my nuckles got wacked by the fan, it scared me but was nothing

Enjoy your MBC and boost guage they're fun but take your time installing and have your plan drawn out on paper and give yourself ample time before you start, because you will rely on this simple setup for the life of your car

 

would it be easier to get to the wastgate actuator from the bottom of the car? cause it's quite a tight fit if i go from the top? would it be easier from the bottom?

all this help is great! keep it up

 

If you remove the radiator fan, then the rest is gravy.

I remove 3 things: the airbox, the battery, and the one radiator fan. That allows me to get to all connections without disconnecting any of the IC piping.
