Hi everyone
first of all i hope i have posted in the right section
i need a little help
i have a GTB2260VK conversion on my ibiza pd130, along with a tubular manifold, 3" downpipe and a MAP suited for the setup
after a few months i developed a wierd issue that nobody has been able to solve yet.
when boosting in 4th 5th gear several times in a row (getting the turbo really hot), it starts to surge whilst accelerating. like, when you floor it, the boost will creep up to 1bar (2.2max in normal situation) but it will start fluctuating and you hear a LOUD "sututututut" noise
the turbo has been sent away for inspection and was discovered that the vanes had broken due to "metal objects" (so they say). so i purchased another turbo but still having same issues.
today the outside temps were 32* and the problem happens each time you boost in 4th gear or above. dont even need to do it several times in a row. so its as if only when the turbo is really hot
ive changed the MAP (3bar), Maf, 4 injectors, different air filter (now on AEM), ECU, coolant temp sensor, crankshaft sensor, camshaft sensor, vaccum block. almost everything.
i have a original seat sport intercooler fitted too with hard pipe work supplied by darkside. also, EGR and ASV delete!
any help would be much appreciated!
Thanks
