I would like to know some of the specifics of the RB25DET Series 1 Turbo. From what I have gathered it is a T3, but I am unsure of the manufacturer. I found an eBay sale for a Garret T3 that was "for the RB25DET" that upgrades journal bearings to thrust bearings. Can anyone elaborate on the turbo or this particular upgrade?

I can do a little bit of Excel work on when my turbo spools and then I can get my school to pay towards the rebuild when I apply it to the class. So I would like to jump on this opportunity to "freshen up my turbo".

I addition to this I have read a lot the the ceramic compressor wheel causes some problems and was wondering if I anyone had more info on upgrading this.

Its a T3 turbo made by Garrett.

I dont understand what your going on about with the bearings, thrust and journal are two different bearings in your turbo.

You can get a steel turbine wheel to replace the standard ceramic wheel which in turn allows you to run more boost as the ceramic wheels cant handle elevated boost pressures.

As far as rebuilding a turbo goes its pretty easy to do yourself as long as there is no damage to the housings or wheels and you mark everything when taking it apart.

If you had of googled this you would have known all the answers to your questions.

I believe the factory turbos on the rb20 rb25 & vg30 are actually hitachi turbochargers

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
