vr6guy 29 Posted July 5, 2011 Report Share Posted July 5, 2011 hello fellow vr6 lovers please please please help!!i have a vr6 turbo and am trying to figure out where all the vacuum hoses go....i have 2 connectors coming off the external wastegate, 1 on the inlet manifold, one on the dumpvalve, one on the intake pipe (between the throttle body and dumpvale). theres also a connector coming of my fuel pressure gage which is on the left of the engine with the two fuel pipes connected to it. does that need a pipe on it leading to somewhere? and theres a pipe coming of a little box shape thing leading to what i think is the fuel catch tank? located on the o/s/f behind the front bumper... any1 know where that pipe goes?i hope some1 can help!! i have very poor running and hope that with all the vacuum pipes in place it will sort out the running....thank you everyone!!!!!!!!!!!!!!!!!!!!

Daverse 175 Posted July 5, 2011 Report Share Posted July 5, 2011 that box shaped thing, is it a cylinder shape? if it is your carbon canistor,the pipe goes onto your inlet manifold for fuel vapours to be injected. as for the other hoses im not too sure, turbos arent my specialty, hopefully someone else can guide you. hope that helps mate Link to post Share on other sites

The lower port on the wastegate is the 1 you'll need to connect to a boost controller, or if your running on the spring inside the wastegate, connects to a positive pressure source - directly off of the compressor housing.2. The nipple of the inlet manifold - is it a standard manifold? And is it about 3 or 4mm diameter? If so it was used for the fuel pressure regulator.3. Your dumpvalve might as well link to the port on the boost pipe.4. Ignore the carbon canister, bin it, its just a waste of space!Hope that helps Link to post Share on other sites

legvw 0 Posted July 6, 2011 Report Share Posted July 6, 2011 The nipple coming out of the side of the wastgate is the lower port, the upper port is the 1 in the end. A picture would help identify which w/gate you have. Basically, the spring inside the w.gate will be rated to a pressure at which it allows the gate to open. So a 7psi spring will give you around 7psi of boost pressure.If you don't run a boost controller, then the spring will control the boost for you, as long as its not too higher rated!Yes, join the small nipple on the manifold to the small nipple on the fpr.1 of the pipes on the top of the canister will be a breather from the fuel tank, which is best left to vent to air (open), and there should be 1 coming from the inlet manifold near the t/body which needs blanking off.

legvw 0 Posted July 14, 2011 Report Share Posted July 14, 2011 Have you tried what I said? You could also try just deleting the extra fpr and just using the standard vr fpr. Link to post Share on other sites
jims13 6 Posted July 14, 2011 Report Share Posted July 14, 2011 ok , vac feed from the dump valve can go to the nipple on the inlet manifold , the lower one .the nipple on the samco bend can o to the vac source on the wastgate .the fpr needs to be tapped into the standard frp vac pipe. but if your running the software and larger injectors , do away with it.if not do it like that ..i can supply software and injectors etcsend a email to info@jpautomotive.co.uk if you want anymore infojim Link to post Share on other sites
vr6guy 29 Posted July 17, 2011 Author Report Share Posted July 17, 2011 Hi guys, I have tried jims idea and have tried pauls... Engine wont start at all now and the oil light started flashing again. When I crank it over it goes to start then cuts out straight away. Have put fresh petrol in it as well.:'( Link to post Share on other sites
