Hello Everyone,
I have a S13 SR20DET in my S13 Hatch with a ISR RS3871 turbo, 550c injectors, AEM ecu, Tial Q BOV, etc. A few months ago my exhaust manifold cracked and right before that the turbo went from fully boosting to 15 lbs, to barely hitting 5 pounds. After thinking it was due to the exhaust manifold leak i got a nice DOC Race manifold and installed that, with no luck. still boosting to 5 lbs, i replaced the wastegate actuator with a HKS adjustable one. still nothing. I have now replaced the Tial Q with a new one, new spark plugs, checked coilpacks, boost leak tested, turbo has no shaft play and no signs of damage, although i did find a little oil on the turbo side of the intercooler piping, sitting at the bottom where it meets with the intercooler. I really need some help here if anyone has any ideas i am all ears.
Thank you in advance
