2G Is this a Boost Leak?

[Tkzdsm]

Recently I did a 16g turbo swap because my old turbo was leaking oil into the downpipe and when seeing if things were put together back right i noticed that the turbo sounds and acts a bit differently now in comparison to the 13b i had, i dont really look at my boost gauge so tbh i dont know if i have boost going on thats pretty stupid of me, but past 5k rpm i cant build anymore boost it seems, im going to check my charge pipes and what not. anything helps thank you.

Edit: the boost gauge doesnt seem to move whatsoever, but I dont know if it ever read in the first place because I just never looked at it. The turbo came with a new wastegate on it and I didn’t adjust it at all, could this be it? before with the older turbo and wastegate I didn’t have this problem.

A stock boost gauge?

Then you likely installed something Incorrectly.

You had a 13b on a 2g? Manifolds are different on those. Tell us exactly what you have installed now. 1g or 2g exhaust manifold?

Did you use the fire ring on the turbine exhaust inlet? All other plumbing is in place? BOV? wastegate connections? Pictures would help also.

All plumbing is in place, i’ll check connections again, all my charge piping is connected firmly, I’m not educated on what a firing ring is on the turbine inlet. i’m pretty sure my turbo was a 13b when I searched up the serial code on the side. The manifold didn’t pose any problem, it bolted right up, i’m pretty sure it’s the 2g manifold, the turbo sits flush with the connection. I can send more pictures later when I’m home, but this is the only one i have of the engine bay with the old turbo

You probably had a 14b. 13 from an auto 1g car take a different manifold. The fire ring goes between the manifold and turbo. Many people elminate it. I mention it because if you try and use a 13g or 14b ring in the wrong situation it doesn't fit and can block the orifice.

Your piping suggests you have a front mount IC and now you have a 16g. If you're all stock as your profile suggests you are asking for trouble. Stock fuel system can't handle it.

I know but I am still running the stock amount of boost 8-10psi if i remember correctly , if I choose to turn it up then would I need more fuel to deliver it, also 650cc should work if I do want to turn up the boost right.

We can't answer that without knowing more about what you're trying to do, tuning solution etc. It's not that simple.

this was the issue, it was terribly wrapped in electrical tape, it probably didn’t blow until I installed the 16g, does anyone know what this rubber hose piece is called exactly?

It's a rubber elbow but where in the car was it? If it was part of the intercooler plumbing you just need to know the inside diameters and the general lengths to get a replacement. It doesn't look like a stock part.

It also looks like something from home depot. Not suitable if that's the case.
