DERTY New Member 21 Member For: 11y 5m 12d Posted 16/09/13 06:56 AM Share Posted 16/09/13 06:56 AM Hey guys recently purchased a 2002 BA mk1 xr6 turbo. Noticed lately that it has lost some severe performance issue but its a intermediate problem. Has been rebuilt less than 30k kms ago and has crow valve springs. basically stock with a turbo smart BOV and a flash tuneThe problem seems to be under WOT it lacks serious power, 9 times out of 10. every now and then it will go awesome, but most of the time its very sluggish and, Its been flashed tuned and the boost gauge seems to fluctuate between 13-15 psi when under full boost. Had it scanned by a friend and o2 sensor is all over the place so it needs to be replaced, but is this causing the loss of power? Link to comment Share on other sites More sharing options...

DERTY New Member 21 Member For: 11y 5m 12d Posted 20/09/13 11:50 AM Author Share Posted 20/09/13 11:50 AM Took it to bruce the other day, found a split throttle body hose.... replaced it but still the same, Clean boost solenoid up and replaced hosing, Had it put on a few different "scan tools" OBD2, FORscan and got no errors. Took BOV off to see if that was the problem, no different. Turbo and a little bit of play but nothing major but the intake piping has quite a bit of "blowby" oil??. He also told me that car has 60lb injectors, possible fuel pump upgrade and typhoon rods.20/9/2013- Car started a bit off a misfire on my way home. only did it for the last 10 minutes of the drive, was spluttering at around 3500-4000rpm. Bought new genuine plugs witch I plan on gaping to 0.8.Replaced so far:Air filterTB rubber02 sensor Link to comment Share on other sites More sharing options...
