hey guys, just an update on the issue i'm STILL having... well, as per my last reply i was blaming the boost controller, but i take it back as i have spent a few bucks and bought an ebc Apexi AVC-R, nice unit, but very shortly after putting it in i found out that it did not fix my problem.
had a chat to a guy in performance shop and he suggested that i could have a problem with exhaust that i also installed right after the intercooler... the threory he had was that the acuator was not opening up the bypass 'channel' for the excess exhaust fumes..
so i took the cover off the turbo and surely enough found out that a bracket that was installed to hold the turbo cover was blocking the acuator of doing its thing (on the photo attached, the bracket that was installed is that transparent block)... i took the bracket off and the bypass channel was still struggling to open, there was no choice but to take the dump pipe off and see. once the dump pipe was off i found out that the welding was not 100%. i used a file to smooth it up, took a while, but in the end once fitted back on the car, the acuator was able to open up the bypass thingny, BUT when i went for a drive the car was still overboosting (sorry forgot to mention, apexi boost solenoid was set to off, which in theory would give me only 5psi as this is what r33 acuators are set for).
so, now i think it might be the acuator is now stuffed by me having the bracket thing on for a few months...
my next step is to get a hold of an acuator and swap and see if that fails, might put the old dump pipe on to see if it help at all...
ps. if anyone has an acuator of an r33 s2 let me know
