I need help deciding which trim to use for a 1.8L GSR integra. I found a fairly new T3 Garrett at a junkyard with the exhaust turbine A/R of .48 and a compressor trim of 60. Would this give me a lot of turbo lag?

I am trying to get minimal lag with boost pressure of 6-20 PSI. I want to use stock internals now but then have enough pressure to boost higher later. Please let me have your suggestions.

Also what are the benifits of using a T3/T04B vs T3/T04E turbo?

And the difference between a straight T3 turbo and a T3/T04B?
