im considering upgrading to either of these options
HKS GT RS
Garrett GT 28
or a used BBT28...
problem is i dunno which would work best on my motor....
spool up and all the rest of it...
my motor is a 4AGTE with a big port head on it...
last dyno read out was 145kw atw on 14psi....
so does any one how either of these options would respond with my current set up???
Cheers Will.
