Okay so to all my fellow turbo guys. I need help

I keep blowing up turbos

So this car has seen and blown up 5 different turbos, I’ve made changes to my setup that I thought would be necessary. And at this point I don’t see what I could do to make my setup better!!

My oil feed is ran from a sandwich plate, I don’t run a restrictor. I am running a 5/8”/10AN return line to the oil pan. With one 45 degree to a rubber hose into the pan

My last 2 turbos which blew up were the Maxpeedingrods street performance T04E turbo. This is an upgrade from my previous $100 eBay turbos. I know it’s still Chinese made and it only cost $260 which I know is still cheap. But like come on, I haven’t had a turbo last more than a week in this thing, like WTF… I have seen multiple builds push high psi on these cheap turbos without issues.

The car is dialed and tuned for 18-20psi of boost

It makes some big backfires and flames, which I know could be stressful on the turbo









And let me explain how my turbo blew up last night and pretty much how the rest of them blew up. So I was going for my regular pulls, then next pull I do it DOESNT BUILD BOOST. And I can hear the turbine literally eating the inside of the intake side of the turbo. If I give it enough RPM it eventually spins fast enough to build boost. So the turbo is already fucked so I keep beating on it then eventually it starts spewing burnt oil out like a chimney.

 

If your turbos are spitting out oil…either your feed line is too large or the return line isn’t dumping the oil fast enough. That’s your issue…besides the hideous downpipe

 

... and where do you think all of that metal is going while you are beating on the wounded turbo ?

 

Buy a Garrett and run the proper oil restrictor

 

Cheap turbos need finishing work. They may or may not have had QC.

They are OK if you check balance and tighten everything up.

Oil-cooled only, no coolant ports on the turbo, is also going to cook your seals way faster. Those turbos are ok for a 1/4 mile pull but heat soaking and daily driving is going to ruin them faster. Get one with coolant ports too.

Make sure you have the right size restrictor on the feed line. Journal bearing wants more oil than ball bearing. Turbosmart makes an oil pressure regulator that keeps oil around 40psi going into the turbo.

Like other said return line must also be sufficient and slope right into the pan, dont fight gravity

 

Buy better geniune turbos, run an oil restrictor, angle the CHRA so the drain is pointing straight down, no 45 degree fittings at the turbo.
