Thanks man. Yea im somewhat new too, but this is totally a lesson i dont need to learn, but i guess glad i am? Yea now that you mention it that shyt is pretty funny bout you hearin about me in different places. Neway i forget his name tho who worked on my car, it might have been DJ? he was a cool dude i liked him, but he did tell me and i forget his exact words of what the problem was but he said around 4000 rpms there is a problem, like i said i dont remember his exact words, so i took that caution without hesisitating. But somehow, when even not going beyond 4000rpms, the boost still managed to creep so high to blow the engine as is what i believe happened, i dont think they got to indepth with my repairs as of now. One more thing, i still have my old turbo, is it still worth something? And im guessing this isn't even worth mentioning to mazda about the old turbo? Because i thought it was some bull myself....They mainly blamed it on my TBE creating too much back pressure thus damagaing the bearring or something and thats how the oil got in and after that i guess they said the turbo was done. Cuz ya know i thought the idea of a TBE is to relieve the turbo more than creating so much back pressure....just wanna hear your thoughts, sorry for being so long but thanks
Turbo-back exhausts do not create back pressure... they reduce back pressure. This sometimes causes the turbo seals to leak a little oil (usually at vacuum idle) which causes the smoking. I've heard full synthetic oil smokes more than traditional oil. Catless TBE are worse because no Cats to provide any back pressure at all. I've had no problems with my CPE Catted DP.
