Well took my car to RB Motorsports who specialise in skylines are are regarded as one of the best tuners of them on this country so after bribing them to book me in with my zed i have spent several hours trying to sort my problems out.

 

Bad news first, still not boosting properly on the boost controller or wastegate springs!!

 

Good news, checked everything and apart from a sticky BOV everything is fine, they checked both wastegates, turbos, pipework, plumbing etc etc

 

So you may be asking yourself why is it not still boosting right?? well simply its not getting enough air into the turbos to produce enough boost, we have her progressively making boost upto about 0.8 bar now but the boost then falls off slowly so she is faster but not much faster!?!? but at least we found the problem with her and know now what to do :)

 

So roll on 850cc injectors and 1.5 bar :dance:

Mmm... blocked exhaust? if it can`t get out it can`t suck in

didnt check the exhaust but they did remove the throttle pipes to see what pressure was coming from the turbos and it was fine but i will get the wife to dip the throttle and i will feel the exhaust unless theres a more scientific way??
