Hello everyone,

i need some help identifying this turbo, all i know is it's from a Volvo Truck, and that is A/R .71, could anyone please help me?

Need to remove covers and measure inducer and exducer of both compressor and exhaust wheels from the peterbuilt or Volvo rig on-center truck turbo

Its t6 flanged and probably a gta45 or gta47

Way to big for a Honda app as you can't get a different turbine housing.

There should be a tag with numbers.. give us that

i've been told its a T4 flange, i really don't know much about turbos,

the numbers on the pictures are all that the the turbo have imprinted so i can't really provide anymore numbers =(

forgot to take picture of the turbine inlet, but its twin scroll.

Its a t6, no question about it.. turbine housing is huge, like a 26cm houaing .
There should be a tag on the center section with numbers on it.

You'll never be able to use this thing on any Honda based application... think big v8 drag car and you're close to what it could be used on.

Post a pic of the turbine inlet and measurements on the distance between the mounting holes

And even if it is t4 flanged, the housing is too big and the turbine wheel is too big... not to mention unless you're trying for 800-1000hp the compressor is too big

i left the turbo at my friends shop, i'll try to take some pictures tomorrow, its gonna be used in a compound setup with a smaller turbo, but we first want to know about this one so we can match the smaller one.

thanks, i'll post the measurement pictures as soon as i take them

A compound setup on what? Even in a compound its too big.. this turbo came off something like an 18 liter turbo diesel

good night everyone,

today i got to measure the wheels and flange:

* Compressor Wheel:

Inducer: 63 mm
Exducer: 97 mm

* Turbine Wheel (here i suppose its the opposite to the compressor wheel, am i right? :

Inducer (bottom of the wheel) : 82 mm
Exducer (top of the wheel): 75 mm

Flange is twin scroll and the distance from the flange holes is:

123 mm x 80 mm


i looked for any numbers or anything imprinted in the middle of the turbo, but there is absolutely nothing, however, there are 2 rivets in there that i guess used to hold the model/serial number plate... i asked the previous owner for it and told me that the friend who sold it took it as ornament and now is nowhere to be found

hope the measures could be of any help identifying the turbo.

thank you

Well. there's not much more to "identify". Let's get to the meat of this already.

Based upon the wheel measurements, the contour of the inducer and the divided housing (That's not a twin scroll despite marketing tactics), This is good to a bit over 600whp-750whp and would be best used as a "Mean highway monster" or"race only" application. There's no point strapping this onto some stock engine, or even an aftermarket piston/rod without aftermarket sleeves.
The turbine housing is HUGE, even with the nice aerodynamics of the exhaust wheel which is similar to F1 Turbonetics, or GT design Garrett. But its SOOO large, you'd better not ask about whether or not it will be "laggy".. Absolutely. Max pressure wouldn't be reached on most sub-2.0 litres until easily 7000rpms.. maybe more. Hard to say.

Your manifold will need to be custom designed to fit that On-Center Turbine housing as it is not like the Tangential housings that most people use, even on big turbos. That means custom flanging, custom fitment, custom everything. Could you fit another housing on it? Possibly, but you need to go to a Garrett dealer that deals in OEM applications with this turbo in hand to see if there are any options. You can't do this even with having the serial numbers and tags and try to call it in somewhere. This is an OEM application, you have to try out what fits, bottom line.

This is the quintessential home-brew serious racer's turbocharger. It came from a Volvo rig and is being used on displacement under 1/8th its original size for its intent. This is something you need to run at higher pressures over 20psi to get any use out of it. (My guess is about 75lbs/min-90lbs/min, again depending upon how the compressor wheel exducer is configured)


I'd have to see the exducer wheel itself with the compressor housing removed, but considering it is a splitter blade designed wheel, the actual power output can only be determined if there is a reverse rotation of the backwall of the compressor wheel. If its a straight-walled exducer, power output will be reduced greatly, but torque will still be high on the application. (I know that was a lot, but if the compressor cover were removed, I'd show you what I mean)..

Would this work on a Honda? Short answer; yes with an if , long answer;... No, with a but..

Yes.. If your intent is strictly to highway runs or strictly drag racing with no regard for lag

No... This won't work on a 300-500whp street car But.. If you think you're going to build a serious motor around it, it could still work for you.

If I were in an area that didn't have options, or the budget, and I were a serious racer with a fully built motor, I'd try it out.. This is a "strap-it-up- and-we'll-see" turbo.. So no, no one else has used one exactly the same, so don't bother asking..

Thanks for that answer

I've been truing to upload the pictures with the housings removed but for some reason my internet is being gay, ill try again tonight.

As for the engine, its a c5 darton sleeved, fully built, crank balanced to 11k rpm, head is fully built also and we are planning to run it up to 9.5k, car is for drag only and an ocassional sunday driving just for fun.

As for the custom everything, since we intend to build a compound set-up we already had in mind that "custom everything" issue in mind, so its not a problem.

As soon as i'm able to upload the pictures i'll post'em

here are the pictures of the wheels withput the housings...







just for size reference

Still, t6 housing that size + the size of the turbine wheel... its still too big for a homes drag car... that's a turbine side for drag mk4 supras...

That is a T6 indeed, and even on a compound setup, i've seen smaller turbos still not feed enough pressurized air to run this. At least the compressor wheel backwall is contoured to help with upper end power, and the turbine will support up to about 800whp.

Good luck with your project. Nothing more about this to talk about really.

I have a feeling this won't work lol.. call it a hunch ;-)
