It's a journal bearing turbo - absolutely no requirement for an oil line restrictor unless your oil pressure is too high, they are regulated to 5bar anyway and rarely hit that when the oil is warm which is fine for a journal bearing turbocharger. Other people have run that same GT2052S without any problems in the past. A ball bearing turbocharger is different and requires a maximum of 40-45psi (3bar) maximum at full engine speed.

There's almost certainly another issue at play if the turbo is known good. Can you get a photo of the drain in place?

Best ive got without laying under the car in the rain.
Running the gt15 oil drain which was its stock setup. 13mm i.d



Was talking to lapit at fcs and the other lads he was with racing. Was how the whole subject of restrictors came up. Did a little research and found some of the vag boys were running restrictors with them on there pd engines so kinda though ive got nothing to loose by trying as i needed a better fitting oil line.
Ngl i really think theres somthing wrong with the engine like you say
