for starters i have a 2006 wrx with a catless TBE. stock up pipe, silicone intercooler hoses, stage 2 tune AP, stock TD04L turbo. these are all the mods that im aware of on the car. for starters the car will only ever have a vacuum pressure of anywhere between -11.5 and -8.00 at idle. while driving the car will never reach peak boost and will almost hesistate at times of WOT. my car burns oil like crazy, almost a qt a week, but im replacing my turbo with a TD05H in hopes that it is just a bad turbo seal. recently i did some work on the car where i had to disconnect the battery. on my test drive after reconnecting the battery my car hit almost 19lbs of boost! and then another time i was driving up a hill and it was holding 14lbs! only ever done that once tho.
im going in to a local tuner on thursday to have my car tuned for the TD05H turbo and im going to have him preform a boost leak check while im in there. no im not just a kid that baught a subi and am having a mechanic do all the wrenching, i know my fair share about vehicles, however im new to the subaru and turboed life. any help or advice on the problem is much appreciated!
my thoughts on the problem are:
bad turbo(old turbo had no shaft play)
boost/vacuum leaks
bad boost sylenoyd
