    KLR turbo manifold failure

    Hi all.
    Anyone had issues with their KLR turbo kits? Im onto my second turbo in around 5000k and now the manifold has around 6 cracks in it..
    My 6x6 is a work vehicle , loaded to 5500GVM and run 6 days per week.The motor has some wear due to an air cleaner issue, Apon removal and inspection its also found that the turbo and manifold is stuffed. We are now wondering if the majority of the issue is with the turbo upgrade as the motor was fitted only 40k ago.. I don't want to question the quality of the KLR product but I'm pretty ****ed on the lack of reliability with the upgrade.. looking for feedback.
    Cheers

    I did have a KLR turbo on one of my Perentie Cargos go out at less than 10k kms. Sent it back and they shipped another to me and then did an analysis on it. Theu said it looked like it was stsrved of oil, but I installed the second unit exactly the same and have had no issues to date, a year+ later. KLR provided outstanding support and service, so if there is any quality issue you have encountered I'd hope you would find a similar experience to mine.

    Have heard of this a bit before, particularly the turbo. Do you still have the factory log manifold laying about, if so, put that back on. To be honest, I am not really sure why people with a T motor, go down this path, just fit a better turbo and tune to suit.

    What are your EGTs? Sounds like you are running too hot.

    ?? Thats why I went down this path, it was supposedly a better turbo and manifold set up, with a slight pump tune

    Over $3k better? I don't think so.
    The factory non wastegated turbo isn't much chop, but the factory wastegated one work well, as do many other turbos. Much better options than the turbo they run, but each to their own

    Its 3k better in performance given what we do with them, but if its not reliable then I agree, there must be better options. Whats the wastegate one your referring to?

    What I meant, was you could have put a $900 turbo on, and got the same or better gains than the set up you chose.
    For example, my mate put the klr kit on his perentie, I used a factory manifold and td04 turbo, similar tunes, I made 6kw more on the dyno than him, my set up cost $1300.
    Garret tb2568 is the wastegated one. I believe klr uses the garret gt2252

    Sure but you need to custom build the plumbing, oil lines, crankcase ventilation system, get a manifold, custom build an adapter to the turbo, build the exhaust. Cheaper but requires a lot of work. It is too bad someone does not do a full kit with a cheaper manifold and a larger turbo.
