March 16, 200719 yr I have a stock EA82T with a open 2,5 inch exhaust from the turbo back and since about a week, I have been experiencing boost creep in all but first gear. it rises to about 0,6 bar, stays there for a while (that's normal pressure) and if I keep it floored it will rise again to about 0,9 bar (I let off, thought that was enough without IC) so what's the deal? i've been driving around with this exhaust for month without a problem, so that can't be it, if the actuator is broken I don't think it would chill at 0,6 bar, so I guess that's oke too? please help me, I tired of constantly monitoring my boost gauge...
March 16, 200719 yr hey, how dare you post here before xt6.net. just kidding joost! i'd expect a vaccuum leak somewhere maybe? i would want john from KY on xt6.net to see this, i bet he'll reply at xt6.net, he's the subaru turbo genious.

March 17, 200719 yr port the wastegate, install an EWG, or put the stock down pipe back on. this is what they do when you open the downpipe up.
March 18, 200719 yr Author I swapped the tranny yesterday, so I had to remove the exhaust anyway, so I had a look at the wastegate, and it looks alright to me... what do you guys think about an external wastegate? this should solve my problem right?

One question remains, why didn't it do this earlier? And for the porting is this something I should pay someone to do? or can I do it myself? (how?)
March 20, 200719 yr well seeing as though you are asking how, I'd trust someone else to do it, but I'll explain it anyway. you take the turbo off, pull the arm off the flapper door on the wastegate, mark around the plate to see how far you can go, and take a porting bit on a die grinder and go to town. be careful and don't go outside the line, you'll want to leave a little bit of a lip to seal still.
