Lost My Boost

[kermit]

hey guys. i have a R32 GTR which me and a mate recently pulled off the inlet manifold and throttle bodies to change the gaskets as they were all leaking. now even though everything appears to be back in the right place i no longer can achieve 14 psi boost. instead all it is giving me is 9 psi boost which feels soo slow .

is there anyone out there who has had a similar problem? i cannot see how ( with the restrictor removed ) i can receive less boost than before when i had leaks everywhere. the car runs so much better now and idles properly but i am left with this problem

please help

what gaskets are we talking about exactly, i think the boos is were it should be ,but when you had leaky gaskets it was boosting more but looksing it, but i am no gtr guru so i may be wrong but i think 9 pound sounds right though, hope i was of some assitance

we replaced the inlet maifold gaskets and the throttle body gaskets. all surfaces were cleaned and permatec ( gasket goop) was used both sides of the gaskets.

removing the restrictor in the boost line is supposed to give 14 psi ( or close to it). which according to my boost gauge i had before the gaskets were changed.

could have missed a line to the std solenoid so the turbos are running at actuator sprung boost ... or have a split in one of the pipes that goes to the actuators/solenoid

yeah this is true , recoment checking all you lines that lead to you wastegate

yes i agree. swapp the hoses on the solinoid

Hi, yeah I have the same problem. My gtr produced just over 14 PSI, had the turbos rebuilt, now only 12 PSI??

Replaced actuators, no difference. I also have both restrictors removed???

I would like to know what boost the turbos are actually producing. Is it only 12PSI or is there a leak and only 12 gets to the manafold but the turbos are working harder. Remember the boost guage reads manafold presssure not turbo housing pressure. I'm still working on the problem. The workshop who did the turbos seem to have done a good job. Everything refitted correctly and nice and tight. <_<

I have a similar problem. I have no boost either. but it didnt play arround with my engine at all. i think i just flogged it too hard. theres a small howling noise comming from my bonnet tho....
