Crank lightening, not knife edging

Like other state, the more you leave the stock engine the better which they got their own magic.
Although many of you do not listen to this...
It is the same blcok of a competition Mazda 323 GTR pushing more than 300 HP, backj in PR who have done 10s the crank is stock...\\\\
IMO, leave it alone, the crank in stock trim is bullet proof.

Bingo. Load a dyno as if a Miata weighs 3500LBs and a 35R will spool like 2860 in terms of RPM.
The lighter crank means you are probbably spending less time in 1st, 2nd , etc gear, which will slow your spool a bit. Basically you have less time at a decent load state to spool the turbo. So chances are the perceived boost threshold will be higher, despite the car accelerating better.
From what I can see the weights are for driveability and NVH reduction more than for the engine itself, like the balance shafts you see in a lot of I-4s.
