When the wear limit is .003 I wouln't want to go looser than .001" if possible, because you would just be that much closer to a rebuild. It will wear in before it wears out. Yeah, at 0.003" your pistons will be slapping the bore sides. I could only think of the extreme cold in Alaska as a reason for so much clearance.
TDI. 2000 Jetta TDI. Nov 9, 2017. #5. This really depends on whether you are intending to stay at stock engine power levels, have mild aspirations for increase, or are intending to go wild with it. The Luk 17-050 is a good cheap option for a stock level car. The G60 flywheel and VR6 clutch disk and pressure plate are good for a relatively cheap stock turbos can take 1.6bar boost max reliably. more can be done but it will not last.

The oil inlet thread is M10x1.0 and the oil outlet threads are M6x1.0. This turbo is not watercooled. Service Kit. The turbo theory in short is Power is directly proportional to amount of fuel burnt successfully. For more power more fuel to be burned, but within limits of the stoichiometric air / fuel ratio (14.5 : 1 vol - slightly lean for diesel in practice for avoiding unburnt fuel or soot), the upper limit is by cubic capacity of the engine. What I have researched: Average life appears to be 300-500k miles. And, as mentioned, it's all about maintenance. Catch-up maintenance can be spendy. Look over my project link in my signature. This is a worst case scenario. Even if it is 'certified', I would have the timing belt replaced. dLrLV.
