Posted at Nasioc but didn't get much response
hoping to see if anyone on here has the answer to this :
hi guys,
I used to make full boost on my car until I replaced the vacuum lines on connecting the turbo inlet and the BCS . I simply grabbed a vacuum line sitting in my house and replaced it (it has a bigger diameter than the factory). I replaced the vacuum lines because I noticed cracks in the vacuum lines. I did not touch the line with the restrictor pill in it. Also, I touched and made sure the pill is still inside line 1. The lines I replaced was line 3 and line 4.
Right now, I am only making 0.05MPa boost according to the stock gauge. (I used to hit 0.1MPa) before replacing the vacuum lines. I believe this is due to the larger diameter of the replaced vacuum lines.
Anyway, according to the picture below, can someone please tell me the part numbers for:
1. Line 1 - Part # :
2. Line 2 - Part # :
3. Line 3 - Part # :
4. Line 4 - Part # :
5. T-fitting - Part # :
I researched and someone mentioned that the entire assembly part number is 14447AA090 (for MY 03 - 05) . But I am not sure if the assembly contains all the required parts.
Thanks guys
