.48 vs. .63 a/r I have a 92 Civic CX hatch with a bone stock JDM B18B and a JDM B16 LSD transmission. Currently, I am running a T3/T04B turbo with a 50-trim compressor wheel and .48 exhaust. I will be upgrading soon to a T3/T04E turbo with a 57-trim compressor. When I buy the new turbo, should I stick with a .48 exhaust or move up to a .63? This car is mostly street-driven, with some occasional trips to the drag strip and autocross track. After installing the new turbo, I will go back to the dyno and get re-tuned. Will I notice a significant power gain with the .63? How much longer will it take to spool this turbo? I have a 2.5" downpipe (no cat) and a 3" catback. Thanks in advance for your input.
