my fears were confirmend

[Underdogpsd]

My truck has a bigger turbo. Someone before I got it changed the collector and dp. Installed a turbo from a 99- up Powerstroke. Now I have a great shape 95 turbo with nothing to do with it. Should I keep it for twins? Lol.

that 99+ turbo isnt nessacerly a better one... its actually a downgade, but it has a wasegate

[Underdogpsd]

Is there one I should look for that's a better turbo that goes off of the 99 up mounting style?

[OBS>SD]

I got a huge noob question, what do wastegates exactly do?

[backwoodsboy]

A wastegate allows exhaust gasses to bypass the turbine wheel.
Helps to prevent an over-boost situation. Can also provide a few more HP at the upper end of the boost range, by reducing exhaust back pressure and preventing the turbo from heating the air rather than compressing it, which is counterproductive.

Ok that makes since. Are the obs turbos as good it better than SD turbos?

Stock vs. Stock the SD turbo is a step down from the OBS turbo. The Banks 'Wicked-Wheel' upgrade for SD turbos is actually just the same compressor wheel as found in an OBS.
There are some advantages to swapping to a SD turbo, but they definitely don't come from the turbo itself.

swap to a 38R turbo, that is a pretty good improvement over stock sd and stock obs, and better than a d66 iirc, the sd is a lot simpler to upgrade from, but a pita to get to as far as where you start out, but hell if someone went thru the trouble to put an sd turbo and mount on your obs, just go ahead get bigger sticks and a 429r lol
