Digsy Posted April 20, 2004 Share Posted April 20, 2004 This might sound a bit rich coming from an SZ owner, but... I was just wondering if it was about time we had a roundup of people's turbo failures? As someone else recently pointed out, it seems to be happening a lot recently. Given my post about durability in General Discussion last week, I thought it might be an interesting exercise to get a summary of who has failed their turbos and under what circumstances just in case there is a common theme to the failures which could be avoided by future owners. Useful data might be: Steel or ceramic. Stock or hybrid. Boost pressure. EGT (if known). Age at failure (in years and miles). Service schedule followed. Other mods (especialy induction filters, oil coolers, etc.) Type of failure (impeller, turbine, oil seals, bearing etc.) Good idea...? Link to comment Share on other sites More sharing options...
Matt Harwood Posted April 20, 2004 Share Posted April 20, 2004 This will only help if people are honest about what they were doing when the turbo's died... Link to comment Share on other sites More sharing options...

Dragonball Posted April 20, 2004 Share Posted April 20, 2004 Originally posted by Darren Blake T Useful data might be: Steel or ceramic. Ceramic Stock or hybrid. Stock Boost pressure. Coming offf 1.3 Age at failure (in years and miles). 70000 Service schedule followed. Yes Other mods (especialy induction filters, oil coolers, etc.) Induction HKS / OilCooler / SBC-ID Type of failure (impeller, turbine, bearing etc.) Blades all gone turbo 2 I really dont want to remember that sound and smoke again OK! Alsothe EGT's were too high cos the fuelling was crap for what I was boosting Same car - hybrids in / 550's / UK Spec Pump / FSE etc - and now EGTs 75/100degrees less despite bigger turbos Link to comment Share on other sites More sharing options...

Digsy Posted April 21, 2004 Author Share Posted April 21, 2004 Well, we could move it to members only if people are suddenly going to get all coy about their driving style EGT would be a good one to log but I guess relatively few people have a gauge. I've added it to the list in the first post anyway. Link to comment Share on other sites More sharing options...
michael Posted April 21, 2004 Share Posted April 21, 2004 Mine didn't really "go" as such but they were on their way out so I replaced them - oil seals and huge shaft play. Steel & Stock Boost pressure - standard up until late last year, then 1.2 bar max Age at failure - about 10 years and 85k Service schedule followed - Full Toyota history and oil changes every 3k since I got it (or every 300 miles recently!) Other mods - IK's, AVC-R, Decats and NuR Type of failure - shaft play and seals I'm guessing that the addition of the free flowing exhaust highlighted the problem to me, had there been more back pressure I might not have noticed it for a while.

Roy Posted April 21, 2004 Share Posted April 21, 2004 ceramic stock 1 bar !!!
