So looking for some help…few days ago me and a couple buddy’s installed the ATP Garret gtx2867 turbo and all the supporting mods(intake,intercooler, charge pipes,downpipe,exhaust,exhale kit in place of cold side charge pipe,and external wategate, and ofc a tune) anyway so we did the install checked if EVERYTHING was tight and what not and flashed basemap from JST and took for a ride home I tried not to hit boost on the way home until I got on the str8 away by my house and once I got into boost I heard a little pop as soon as the boost got built I do have a little DP leak but it was leaky b4 turbo anyway but as soon as I heard that pop car felt like it was non turbo and felt like I was driving a normal focus Se lol some things I noticed was…no intake filter flutter or BOV on exhale kit making any noise and even in 1st gear if i floor it Feels like limp mode. So was wondering if y’all could help me out ik it sounds dumb but b4 I get under I wanna know what I should do and be looking for(no CEL btw)

And another thing my downpipe is DEPO racing brand and it doesn’t line up well with the turbo and when it does the V band clamp on it is all wocky hence why the leak ^ is there anything I can do to fix that maybe a. New clamp or welds ? (It fit perfect with the stock turbo but BT giving me issues )

Probably blew a charge pipe off. Been there, done that. When I blew mine off it was from the output of the turbo, and it basically just pushed it off so that it was wedged between the outlet of the turbo and the body of the vehicle. You're going to need to get under the car with the belly pan off and start looking around. Wiggle joints and see what's moving/loose, re-attach, and tighten things back up.

Tbolt that bish

Yep...what @rob99rt said...charge pipe blew off. Crank those babies down with some t-bolt clamps.

Here is what I was advised by a knowledgeable senior member, I will copy-paste his instruction for you too.

Near the downpipe would likely be from the downpipe VBand.

The vband between the elbow and turbo has a machine-fit step in it (it's a specific flange to the GT 28 and 30 turbos) and highly unlikely that's leaking. It doesn't require a lot of torque to hold tightly either.

It's easy to not have the downpipe line up properly and leak. (This does have a gasket but if the mating surfaces aren't true prior to installing the downpipe vband it will leak).

1.Take the downpipe vband completely off.
2.Loosen the vband between the elbow and the turbo just enough that you can rotate the turbo here.
3. Push the downpipe up against the turbo and rotate the turbo until your downpipe/turbo mating surfaces line up parallel.
4. Install downpipe vband and tighten fully
5. Finally, tighten the elbow-to-turbo vband.

It is leaking from where the turbo meets the downpipe at the top where the v band is bc it won’t seat properly idk why so I should try this and have no issues ^^^^

If you do what W4R said regarding correctly clocking the turbo to meet the downpipe and you're STILL not getting boost (and I imagine you will still have issues since it should be building some boost whether the DP is connected correctly or not), then start looking at the charge pipes. The vband clamp to the DP is after the turbine wheel has had exhaust blowing over/through it. Whether it's the turbo/DP joint, or an exhaust leak further down, it doesn't matter... it's still post turbo. Your problem, I imagine, is on the charge pipe side of things since it won't build any boost... Obviously you need to get the turbo clocked correctly, but I don't believe that's going to fix your boost problem.

I second this. I did a pull with my gtx2971r for a datalog and heard a pop, closer to a pressurized pop than a backfire sound. Got under the car, and my hotside was slighting off from the hose. Tightened it up and back to boosting.
