Harzut?...
what sort of turbo set-up are you running on the A-series?
I run a draw-thru carb. set-up and these type of set-up require a carbon front oil seal as opposed to the std. dymanic (piston ring) type seal. Without this carbon seal the vacuum from the inlet and the closed throttle butterfly on the carb cause the oil from the turbo core to be sucked into engine.
But as I think I can see an intercooler in your avatar I doubt you running this type of set-up if this is indeed the car in question?
I`v been stung a few times with `sight unseen turbo purchases`, I bought a T3/4 hybrid (which had been "re-built") I fitted over sized bearings and had the shaft re-ground. I then had to buy a mistsashiti scorpion to fit it to (because the manifolds looked to good to bin).
The latest and greatest tarbin I bought was an ebay "chinese" item, I cost me $200 on the front door (tas.), It was way too big for the A-Series, So I fitted a SIV rx7 compressor cover and fitted it to my 280c.
I know thats not much help, But chin up dude and " Always speak soft, sweet words.....Because one day you might have to eat them."
