Master Power R444-2 on OM617a failure
It's been a long time since I have really posted on this board, I have been working overseas. I have been driving my OM617a G-wagen with MPR R444-2 turbo, A\W intercooler and MW pump with Tomnik's 6.5mm elements and had the turbo fail today after 4-5000km's since the turbo was installed. It has a huge amount of radial play and has rubbed the housing, I am looking for advice on whether this is likely caused by overboost (25-29Psi at 4000+rpm) from what I can gather from the turbo map http://www.hevosvoima.com/shop/index.php...ts_id=7250
I should be within the limits of the turbo at this boost pressure although I am not well versed in reading turbo maps?
The other thing I thought of was excessive oil pressure supply to the turbo as I was not sure of whether I would need a restrictor in the supply line but I thought that since the stock turbo used the same line from the same location and the new turbo also had what looked like to built in restrictor in the housing that it was good and from searching on here nobody installed a restrictor unless going to a ball bearing turbo? I would greatly appreciate some insight as I need to get a new turbo and want to avoid a repeat!
larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
I'm no turbo expert, but a larger wastegate might help you out

If your issue is overspinning the turbo at high rpms, a wastegate could help. I'm nto the turbo expert though-I just slap shit together and hope for the best.

It's fairly normal on Subaru's to port the internal waste gate in the exhaust housing to make the casting smoother so it will flow better
