Default NA 1.6 turbo charger question

hi guys. i turbo-ed 1.6 liter miata with a 25 turbocahrger .42/.49 A/R (shitty small turbo maxed out!!)

i want to upgrade to bigger turbo because ..

it makes 13psi by 3500rpm and boost drops to 10-11 psi from 4500 to redline and its killing my top end power..

my questions is will this ebay t28 with a .86 A/R turbine housing be hella laggy? like has anyone used a t2 based turbo with a turbine housing that large or close to it and how fast did your turbo spool up?

looks like im gonna do it so far i know is the smaller the wheel the less difference in spool up ar makes so i should be good!

as far as i know from experience going to a .63 stage 3 on a T3 from a small .48 ar make a world difference of more lag from previous set ups ive built
