What exactly is the difference between the T3/T04B and the T3/T03? They have the same .48/.60.

Someone help a homey out.

 

trim size

 

Yes and no...trim size has a little bit, but it has a t4 (although tiny) compressor housing yielding a slightly different map...
standard t3-60 trim...
This is the closest to4b s-trim I could find, so I'm not sure if it's correct.

I have a feeling though if the standard t3 you're trying to compare has a .48 a/r exhaust housing (more than likely a t-bird or merkur t3) then it's only a t3 50 trim at most...pictured here...
Hope these help some.
