Hey there forum what's up? I need an answer to a few turbo assembly questions. All help is appreciated.

I need to know what all is involved and how do you match up a turbine housing. I have the opportunity of getting a turbo that has no turbine housing and I am very interested just need to know what all I need to assembly the rear.

The owner has no idea and says all he knows is that the rear is a T4 ptrim and the turbo has no identifying numbers. How would I know what rear to get? The turbo is also a ball bearing turbo. Now my dilemma is a have a turbine housing sitting around and wanted to know if it will fit a t4 ptrim turbine wheel. The number on the housing is 410401-0036.

Can this housing be used with that turbo and also what else is needed in order to assemble the turbine of the turbo? Do I need a plate for the rear of the turbo to attach to the turbine housing? I am lost when it comes to this and would like some assistance please.

it sounds like you are buying someone else's problem or mistake

why not just buy an off the shelf unit that works and has a proven setup?

I have a turbo setup on my car already and was just buying this as an experiment as it is dirt cheap and I had a rear housing just lying around and wanted to know if it will fit and work.

What you need is the correct housing for the turbo.

Without knowing what rear wheel is on it, its not going to be an easy task.

Either way its an old donkey tech turbo to begin with by the sound of it

Ok all the specs he has on the turbo according to him are its a garret ball bearing turbo, Comp side: 67mm inducer, 82mm exducer, Turbine side: t4 ptrim thats all the info on the turbine side, the rear housing I have is a garret 1.00 t4 divided housing with the numbers in the first post and I was just wondering if it will fit and what the turbo will produce as an experiment and what spool would be like. I was thinking it would be ok as it is ball bearing and the comp wheel has the same specs as 35r just the inducer size is a bit bigger so it should flow more and I was thinking it would have the same spool.

What I wanted to know is how does the turbine attach to the housing is there a backing plate or clamp that I would need to buy in order to attach them? Pics of turbo are attached.

ahh... no.

If you go larger comp, it will take longer. Simple as that.

IMO with a T4 1.00 housing, with a large front side - it'll be laggy as all shit, especially on a 2.5ltr.

Poor choice/combo. But then you've gone the cheap option a few times now ... Buy a decent turbo once and be done with it!

Can I ask, why do you keep posting about random truck junk yard turbos?

Do you realize you can get a brand new or highflowed turbo that is proven to work the tune of $1000? The work/effort/money involved in fitting these random turbos will far exceed the benefit you will see.

Please begin to reconsider your options, this site has a million and one to offer.

Thanks for the response! That is half of what I wanted to know, how it would spool and what power figure it might make. I still do not know if the rear housing I have in the shed will fit it cause if it is a simple bolt on case, I could still acquire it put it together and pass it on to someone with bigger displacement.

I have decent turbos, the gt35r and hx40, and if you remember from a previous post I had bought the wrong housing for the 35r and since I had a brand new housing sitting around doing nothing I just wanted to know if the housing would simply work and if it was a bolt-on case. Just was doing this as an experiment and wanted you guys opinions on what kind of power and spool time a turbo like this would have on a rb25det. My car is up and running fine with the hx40 just in the tuning process.

Sure you can ask and of course I realize I can get a brand new turbo to meet my rwkw goal for $1500 plus. The answer to your question is,... to learn, If you read my first post you would see why I am posting about this random turbo, to reiterate it I came across this turbo for a dirt cheap price without a rear housing. I had a rear housing that I had bought previously just collecting dust and was wondering if that housing would fit this turbo and if it was worth the time. The only info I had on it was that it is a t4 ptrim rear and wanted to know if anyone knew if the housing I have sitting up would just simply bolt on to this turbo and the spool time and rwkw it would produce.

    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
