i have a 2002 wrx it has full decat,filter,uprated fuel pump and sti intercooler it has a remap and produces 15 psi i have fitted a megan racing manifold, sti injectors,aps cold air induction and a new td05 18g turbo the car now only produces 6 psi i know that it should not be driven hard till another remap but i only drove it for 5 min and only up to 4 thousand rpm could any one tell me why.Do you have to set the actuator when you buy a new turbo cheers MOMO

 

Suggest you talk to the people who sold you the turbo, or Andy F or Pavlo at Zen Performance.
Dosn't seem correct.

thats wot i thought i got the turbo from andy f i sent him a pm so will wait and see wot he says just thought i would ask to see if anyone has come accross the same thing ( weird) MOMO

 

any ideas anyone MOMO

 

It could be due to one of several things.

It's certainly possible that the arm on the waste gate needs adjusting, but whan you swapped over, did you re-fit the restrictor ?

Or iit could also be a leaking pipe, or something else that was done during all the changes.

Forgot to say that I'd be very carefull about driving it on bigger injectors, until it's re-mapped.
