Hi guys can anybody recommend a reputable supplier of second hand turbos?? Ive tried dismantling and cleaning the turbo but it still loosing power, Turbo definitely fubarred and need one immediately. Any recommendations appreciated

Are you sure it is the turbo at fault?  Not a boost leak, vacuum leak, vacuum control issue, MAP, MAF or CTS sensor problem?

100 % Had it checked by turbo specialist as well as another mechanic..i can get recon one here in Ireland for 340 euro but seems the jury is out on the reconditioned ones..checked some salvage sites in the uk and theyre all coming in around 250 euro plus shipping..expensive piece of kit

That is a reman part, but carparts4less (basically ECP) have a range of different ones.  At least you would be buying from a trusted name...
