boost line sizes?

[deano1978]

Getting limp mode on up hill loads. Going to start with the hoses...
Can people tell me what mm (size) the hoses are i need to replace?
And vacuum lines?
Can hear a slight swoosh turbo noise at idle when reving? Maybe turbo?

Done the mr muscle a couple of weeks ago.

Cheers

if your getting a swoosh then it sounds like a boost leak somewhere

Ok,where would i start? Which is the main boost line? Should i start at the n75 line?
From what i read?

 

[stu_m]

the N75 valve operates the turbo it has vac lines on it

its the air intake that had the leak so it will be from the turbo to the inlet manifold

is it a petrol or diesel?

Its diesel stu.
