Dude. What are you smoking.
6258 and 6758 are the exact same but a bigger compressor wheel and machined out housing.
You would have to then rebalance the turbo, buy a new compressor housing and wheel.
You buy a supercore and put your old turbine housing on it.

The external dimensions are the same. The 62 and 67 have different internal dimensions, obviously. You cannot "shave down" a 62's compressor housing to fit a 67, nor can you "slap on" a 67mm wheel to a 6258. You change the entire CHRA (including turbine wheel) and compressor housing.

People will complain about the shifter no matter what. There are people who think the 6-speed is simply undriveable, for instance. I could tell you what I think of those people, but I'll get nasty emails about it later, so I'll refrain. Needless to say, the T5 is a direct-mount shifter, I'm sure it will be fine after you get used to it.

True. The miata 5 speed feels like you're shifting against some ball detents. T5 feels like a rifle bolt. When I'm cruising thru my neighborhood, you can hear the shifting echo against the houses. Snick-SNACK!
