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?

THANKS!!

 

It will be fine. Go for it.

 

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
