Default Which 2871 does Savington have?

Which GT2871?

There are 3 trim options for the compressor, and at least 2 turbines and 2 a/rs:

You can usually tell from the compressor housing. There is only 1 turbine option and 2 compressor options. Not sure where you see different turbines in there...

Neo, I think you can get it with a T3 housing in .63 or .82. Too lazy to actually check, though.

Your turbine housing is too big. I have a .86 and it hits target boost at 3200rpm. I should have gone with a 2554.

You should have gone with VVT. watch that 3200 rpm number get smaller when he gets his isht on a dyno.

this statement is kinda funny.

I'd love to see a test of how comparable the .48 T3 is to the .64 T25, and the .63 T3 to the .86 T25.

I think that's the exact term I used when I found out my boost protection was set at 1.5psi after the install...
