Well I'm on my way towards a turbo tib as a few of you know but I'm trying to learn along the way.... and since it is inevitable, stupid questions will arise.... like is this turbo that I bought internally wastegated or not??

thanks

Now I think that the wastegate is the round piece with the hose going to the exit of the compressor, my thinking is that it's to measure the pressure exiting the compressor so it can control it??

Now if all my previous assumptions are correct, would it be best to leave it in it's current state and just buy a manifold or to convert it to externally wastegated and buy manifold and wastegate?

 

Oh boy, I have to respond to this one.

Yes, your new turbo is internally gated. The piece that the black hose is connected to is the wastegate actuator. The hose vents pressure to the wastegate actuator from the exit of compressor housing. When the pressure gets to the correct pre-set pressure, the wastegate actuator causes the wastegate to open and vent excess exhaust around the exhaust turbine directly to the exit of the exhaust housing.

The wastegate appears to be adjustable, I can't tell exactly if the rod is threaded or not. If it is adjustable, set it to the lowest setting for the time being so that you are only boosting as little as possible. Then turn it up as you continue your tuning.

Personally, I would keep the internal wastegate. If you are asking about this, you probably won't be boosting to pressures that require an external wastegate. I would purchase a manifold that is made for an internally gated T3 and start building your exhaust and charge pipes.

Have fun with your turbo project.

 

thanks drafter!

well, at least I wasn't too far off laugh.gif

how on this adjusting, how can I tell which way to turn it?? I'll get some pics of a better shot of that side tomorrow!!

thanks again

so I'll take off that little clip and screw it all the way out??

 

so it's set at 5, how can you tell?

what would it go up to if I turned it all the way in? 10?
