BHT3B and BHT3E turbo

[Bigfury]

Can someone tell me the differences in these turbos? Found a E model wicked cheap on e-pay.Wound it be a good investment for a set of twins.Install on a 6BT with a VE pump,working under a S300G.Thanks in advance.

I believe the e is for mapwidth enhanced ..etc ie it has thering in the compressor housing machined out / open allowing more air to get to the turbine vanes. I have that turbo for my twins setup..
