Oil, burned oil
Ok, i've been watching the forum for a long time and this is the first serious post.
So i have a 99 1.6 miata(yeah i know im in europe and is imported from japan, rhd yes
,anyways) i've been running a tiny turbo for 2 years a GT1752 at 6 psi. No problem at all except some minor overheating on high ways due to stock rad and the hot temperature of Cyprus. In june i replaced the baby turbo with a Gtir one t28 , and changed oil from 15w40 to 10w40, even on first starts was smoking from the exhaust, white smoke.after a few miles turbo gave up, and a loooot of white smoke, rebuilded it.. the same... Got a new one installed, the same again. This happens at WOT , i put a restrictor 1.3 mm and then 1 mm didn't help. It seems that is the piston rings...it smells a lot of burned oil and the dipstick proved it too. Any opinion and advice would be appreciated. ( made a lot of miles in case you think would have oil in the exhaust from the previews turbo) ..

That's not good. At all lol
Unless you did it wrong or something. And it sounds like you're another one of those careless kids that wants to just throw out a vague question onto the forum and then speculate about it without any real troubleshooting.
The point of a compression test is to specifically identify variation in pressure between cylinders. So you need absolutely precise numbers for each for it to be worth a crap. Similar situation with leakdown, but a bit different.
So either do both tests correctly and get a really good indication of what the problem is, or keep wasting time on the internet with people thousands of miles away from you trying to guess what is happening.
