99 spec turbo stock boost pattern
 

did they retain the 10-8-10 on these guys, in japan?


anyone know what 'normal' is for these to run at?

Also, quickly,

are the stock 93 twins different sizes?

the 99's are, definately. does this mean if I want to make them non-seq I need to make sure they are the same size?

When the 99 Spec turbos were introduced, they had also increased the base boost to 11 PSI. However, that's not controlled by the turbos themselves.

The 99 Spec turbos should have the same boost pattern as the 93-95 turbos as everything is still controlled by the stock turbo control system.
