I unbolted the oil line from the turbo put a bucket underneath and started the car to check flow and there was little to none (it would have been messy if there was) I got a braided line and done the same thing and I got a few hundred ml in seconds. So not sure how or why but the line was blocked or something.. New turbo has been on for a solid 24 hours, feels and sounds a lot better already. Very relieved so far!

Thanks for all your help everyone, it was a block in the oil line! It's been fixed and I put a steel wheel turbo on the car aswell

Okay thanks for that input guys, if a steel wheel turbo is what's going to fix this problem looks like that's what I'm gonna do, I'm also going to check the oil flow but other then that it's got me stumped. So if anyone could recommend someone who does decent turbo rebuilds that would be greatly appreciated as is all of your input! Thanks

The rear wheel doesn't spin after they blow up, all 3 turbos the rear wheel has been f**ked and the front wheel still spins!! One of the turbos found some of the rear wheel in my exhaust (cat)

Do you think oil starvation could be the problem???

Okay no worries thanks for that!

Hmm well i get about 300kms to a tank give or take. Regardless of how the car is driven, and I've done and re done all of those pipes a few times now.. Is there a simple way to try and find a boost leak? Or shall I just change all the piping and all of the boots cause they're pretty old could be split or anything

Ohh okay!! So a boost leak would just be from loose or split piping from any pipes on the turbo side??

The boost reading seems to be normal also and all turbos have had their own actuators!!

Yeah man 3 quarters so inbetween positive 7 and half. Too much heat on the exhaust side does sound like a high possibility actually because I heard that those ceramic wheels don't handle too much heat very well... It does have pretty poor fuel economy, it back fires sometimes, I think it does run rich because when I bought it. It had an N/A manifold on it and the lines were blocked. But ecu and injectors were still turbo (the car is a factory gtst)

Yeah I thought this too but it's happened 3 times, after everyone's opinions though I'll try a couple different things out when I'm changing over to the new (did you mean rb25 neo) turbo?

Sorry I do mean actuator when I say that. The red hose is connected to actuator, if you look closely in the picture you can almost see it.

On full boost it gets to the 3 quarters line (just under the +7)

Correct the red hose goes straight to turbo. The highest reading on the dash is +7 and under full boost it gets to 3 quarters of that. I cleaned out as the bulk of it I wouldn't be surprised if there was a little bit left behind?!

I was kind of hoping that was the issue hahaha thanks

That red hose goes to the actuator?! Is this what I have done wrong???

Thanks for all the input guys!!!!

I don't have an after market boost gauge just the mercury one on the dash. It was boosting at 7/8 psi. I don't know how to test the oil feed? I know that there is definitely oil getting down there but as for the flow of it? I do have one theory.. One of the coolant lines from the turbo didn't line up to the feed on the car side ( the one right at the back of the head ) and i was trying to bend and manoeuvre it with out breaking it but I failed and it snapped so I chopped it where it had bent put hose in to replace that line.. I'm thinking maybe the hose isn't holding temperature like the steel stock lines and the ceramic wheel is just getting to hot? Such a pain in the ass

No boost controller, one intercooler pipes has a little nipple on it right near the pod filter I put a hose on that and put it to the stock turbo actuator

It's stock boost I don't think there's any splits I wasn't driving it really hard all the time but I wasn't babying it around where either turbo had a sort of high pitch whining but I thought it could be a small manifold leak. And I haven't checked those feeds are they just the holes on the head that the oil and water come out of cause if so they're definitely fine I got showered in coolant the first time I done a turbo change haha

Hello everyone First and foremost if I've done anything wrong with this post I apologise.. first time posting something! I own a r33 gtst rb25det. It is 100% stock under the hood. The first stock turbo on it blew up (half of the rear turbine wheel was in my cat) so I replaced it with another stock turbo from the same model car, this turbo had minimal shaft play and to my surprise a week later the exact same thing happened. I then replaced it with another stock turbo that had no shaft play at all and surely enough it's done it again, I haven't taken this turbo off but all the symptoms are the same as the last 2, no boost, strange whining noise (front wheel spinning on its own? Or air just passing through) I'm beginning to think its something I'm doing wrong so before I make another move id really appreciate any ideas and suggestions. No the oil and water lines are not mixed up. Thanks!
