i'm have a rebuild done on my MY95 wrx i have an sti semi closed block with sti forged intrnal's put in.

i will have a full turbo back zorst and a green pannel filter, if i was to rase the boost to about 1.2bar and add a 225 fuel pump and a fpr to stop if from going lean.



would this be ok? or would i blow the poor girl up?

i have a Z4 ecu

If your running 1.2bar without a remap your asking for trouble.
380cc injectors won't be able to run 1.2bar without an uprated pressure regulator.
standard TMIC will not be efficient at those levels of prolonged boost, causing high charge temps and potential onset of detonation

It would be wise to consider a remap for best results and to protect your investment in the engine rebuild

 

thank's i will look further into it all.
