Hi guys!

I have this turbo charger on my car (a normal 1500cc Toyota). My mechanic, or rather, ex-mechanic told me it was taken of a Skyline, no idea which model. I was also told it was a T28 turbocharger with ceramic bearings (or was it fins, i can't remb). I also remember him mentioning something about it was from an RB25 nissian engine or something.

Look at the pics, can anyone clarify the following:

Is it a T28 turbo?

Are these made by Garrett for Nissan?

Is it a ball bearing turbo?

whats the specs of the turbo? (Turbine and Compressor A/R, diameters, it will be best if there is a compressor map)

Any comments on how would it fare on a 1.5L Toyota engine?

Hope someone can clear my doubts.

it is an rb20det turbo. you can tell by the hole in the commpressor cover that is tapped. normally a nipple goes here to give you a boost pressure signal. it also has 16V on the compressor cover indicating it is an rb20 turbo.

it has ceramic turbine and an metal compressor wheel. it also has ball bearings.

they produce enough airflow for 165rwkw at around 14psi. don't run any more boost than 14psi as the turbine is likely to brake.

it would be well suited to a 1.5 litre engine.

cheers!

Hi there. Thanks for the information.

You were saying something about a nipple, but I do not see a vacuum line connected to any nipple on the compressor housing. Is this ok?

Oh my.. currently I am running at 18 psi, and my mechanic (idiot) assured me that it was OK.

Would you by any chance know the A/R of the turbine and compressor housing?

Lastly, lets say I want to replace the turbo, what are my options for a direct bolt on? Would a Garrett GT2554R be a direct bolt on? (i.e. both flanges on the turbine are the same as this.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
