Internally gated trim, and no boost creep..

[damax03]

Diamond Star Performance sells a 50 trim that is internally gated. I have a hard time believing that these have no boost creep, but I hope they don't, because I really want one of those. Check it out at http://www.diamondstarmotorsport.com/turboparts.shtml and let me know what you think!

The large internal gate does vent off alot of gasses.

Creep is induced or eliminated by more than just gate type (ext or int).

When you can't bypass enough you get it. Bigger turbine housings don't need to bypass as much but don't spool as easy.

So turbine housing and turbine wheel sizing comes into play.

You also need to consider 02 housing and downpipe configurations.

With at minimum a 2g o2 housing and good downpipe it will be fine. I'd recommend a tubular o2 housing.

its a PTE turbo and yes it holds the boost steady.

thanks for the responses, I am getting the 122 performance tubular o2 housing and will have 3" exhaust all the way back with a 3" high flow cat.
That will be sufficient on the exhaust end, correct?

Oh, and also I plan on getting an EVO manifold and getting that ported as well.

Just match that to the ports on what it bolts to. Match the head port size and turbine inlet size.
