I know ive posted on here quite a bit regarding my upcoming setup but i promise ill contribute back as much as i can Heres what i need to know... I have a beautiful turbonetics t3/t4 on the way. Im deciding on wastegate and it seems for me adding an internal wastegate setup would be the best option - it would give me ability to adjust boost at the wastegate and i wouldnt have to either run open wastegate or fab it into the dp. Would a T3 internal wastegate setup work on this turbo? I know it has 5 bolt output so that part is a given - but what about the size of the t4 compressor would this change things?

Here is the one im looking at...

what manifold?

 

Its just a no name cast - company offered lifetime warranty on it at a good price - manifold clearance should be fine and i plan on just putting a steel plate on the 38mm wastegate position.

 

I'm not sure if that exact one will fit. If it doesn't, it'll be because that bracket may not be wide enough for a T4 compressor housing. But my best advice is to call Treadstone and ask them if that particular part will work.

So which turbo did you end up going with?

 

Bought a Tnetics T3/T4 46 trim off a guy on here, yea i just spoke to treadstone and he said it just needed a diff bracket and he would be happy to send it Order placed

 

Excellent - I'm glad that worked out.

As for the turbo - that's an excellent choice of compressor for a small / quick spool characteristic.

What is the specs on the hotside? Meaning - is it a .48 AR or .63 AR? And what stage exhaust wheel?

 

why not just go external wastegate? Will control boost much better

 

Internal wastegates are fine for low boost application.

The only thing to worry about is boost creep/spike - and that can happen even with eternal wastegates. The best solution would be to install a boost controller.
