baturbo321 Member 11 Member For: 12y 7d Posted 08/11/12 08:59 AM Share Posted 08/11/12 08:59 AM hi all, just looking for a few opinions on whats going on with my xr6t,ok so its a ba , auto , process west stage 3 cooler , bosch 404 with surge tank , heavy valve springs , 4inch dump into twin 2half inch , high flow cat , 60plb injectors, tuned by clint , profile autosports, he has done a brilliant job , from what the car was when I bought it to how it drives up untill today has been an exceptional improvement , 321.2rwkw on 19psi , box has been tricked up also ,ok so I had a great play with a supercharged ford ute yesterday , probably the hardest I have pushed my car for a while , and just this arfternoon I started noticing a distinct lack of power, the turbo seems to be screaming ? its making a sort of high pitched scream when I have it on full noise , also its only reading 4.5ish psi on full noise , I have a eboost2 in my dash and I has been on 19psi for the last 8 months or so, since I had it turned up and tunned , the motor is running perfectly , it idles and has the normal power under the turbo , but is only boosting to 4ish psi ???? I checked all the pipping from the turbo to the intercooler and to the throtle body and it all seems fine , so? buggerd turbo ? replacement options ? I had a look at a few aftermarket turbos , if I whent one of them would I need to get it tunned again ? cheers all Link to comment Share on other sites More sharing options...

Thatd be step one, step two check your turbo for shaft play and scraping etc... Also make sure actuator lines are all ok Edited 08/11/12 09:05 AM by bionicxr6t05 Link to comment Share on other sites More sharing options...

baturbo321 Member 11 Member For: 12y 7d Posted 08/11/12 09:21 AM Author Share Posted 08/11/12 09:21 AM lol a screamer would prob be a bit much for me considering it a daily driver , yah im sure clint will sort it , he lives about 2 hrs south of me though so a bit painfull plus I work flat out so finding the time is an issue , I will check the exhaust manifold tomorrow , but to take the heat shield off to have a suss of whats back there , I should be tightning the bolts back up with a torque wrench ,,,? shouldnt I ? I dont have a torque wrench , so just make sure they are tight like a half turn after nip tight style? sh*t was easier back when I had a 4runner lol I dint give a sh*t and actually fixed a heap of things myself cause I wasnt so worried about 'what if I dont do it perfectly' but yah id hate to stuff up my xr6 , its my babie,cheers for the posts , food for thought Link to comment Share on other sites More sharing options...
