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.

      Clutch done also about a year ago got a DCS HD Single Plate. Basically done everything but touch the engine 🤣 But will definitely get a fuel pump and ECU, then start saving 🫡

      Fuel pump and clutch and ecu that’ll get you to about 230 or so kw, after that the sky’s the limit and the budget blows out faster then you can blink

      Should add all mods on the car are done in my ownership. The car was a 1 owner in Japan and I'm first owner in Aus.

      Thanks GTSBoy. Did BC's so not Japanese coilovers. I've already done all the other points you mentioned besides the seat, I like the factory seats and want to keep original look. Done all the fluids and comp tests etc and all consistent and clean. Well and truly used to the power and car as I've been driving it for a few years as it is now. Contemplating next steps mainly. Preference to remain twins too. @Murray_Calavera Paying for labour.

      Hmm. I don't think it is possible. As soon as you start, you will be on the hook for all the money. $5-10k is enough to make it fragile. Here's the list of things you need to do to make it nice, and driveable. If Japanese coilovers, get them measured and tested, then decide if you're keeping them or replacing them. If low rate springs, then consider big ARBs. If high rate springs, then probably leave stock ARBs. Either way, ad decent end links. Replace and/or upgrade all suspension bushes. That's LCAs front and rear, UCAs & traction arms at rear, caster rods at front. I highly recommend GKTech FUCAs, although the step to spherical joints is a step too far for some people. Rebuild brakes front and rear. This means making sure the calipers are healthy, discs are up to thickness, hoses are replaced with braided. Add good pads and fluid. Investigate wheel bearings all the way around, tie rod ends all the way around, upright bearings at the front, balljoints everywhere. Any of these that are still original are likely to be a bit wibbly nowadays. Bride or Recaro driver's seat, with fairly deep sides. Nice tyres. Street performance wheel alignment. Or track focused, if you're not going to use it on the road. Fluids everywhere if not known to be fresh. Now, learn to drive the car as hard as it will go, before trying to add any power. Save up big $$. $5k is the minimum cost for putting a decent ECU into it. A big single, with manifold, new exhaust, injectors, fuel system upgrade, ignition upgrade, triggering upgrade, etc, is >>$10k. None of that (except the ECU) is a good idea on an old RB. You really should put head studs in it, investigate engine health (compression and leak down, real oil pressure at revs, coolant condition, etc) before even considering adding power. There's nothing sadder than the "I added boost then it shat the bed" thread.
