I just recive a to4e turbo But I did not know what trim and what exhaust wheel(stage) does this turbo have .. here are some pics maybe you can help me.
(its supose to be a 60 trim with a stage 3 wheel...) it came with a t3 twin scroll 0.85 back housing .. I also have a 1.00 ,1,15 and 0.78 t3 housings laying around I will test them on a dyno so see the diffs...
Here its goes...














Thanks for the help

 

Well that is a turbo from a navistar diesel engine to the best i could find. There is a part number on the back of that compressor housing shown in your last picture what are the numbers on it?

Turbo number 466772-0004

I can't find one bloody compressor map for this turbo though judging by its size i'm estimating its going to be like a 3071 by garrett. Maybe the part number on the back of the compressor housing will be telling :P.

 

Thanks very much man... I was thinking about the same.(3071 size).. the number is t04e-13 1811671691 r/t
Another number is m9.....
Cheers

 

this number 1811671691 actually is 1811671C91 or should be to match up to navistar no one else i could find had that designation.

Can you measure the wheels turbine and compressor inducer and exducer. Using those we can calculate the actual trim.

Calculations:
compressor trim = (inducer ^2 / exducer^2) x 100
turbine trim = (exducer^2 / inducer^2) x 100

Here's a helpfull image so you know what to measure:

 

Hi.. the exducer is 74mm an the inducer its 58mm comp side
back side 75mm exducer 65 inducer
Thanks for your time.
Cheers

 

Well with those number I'm getting 61 trim so 60 trim on the compressor side
and 130 trim on the turbine.

That means this is a t04e 60trim meaning its going to flow 50lbs/min of air putting it just under the power output of a 3071 gt series turbo. Should be a fun street turbo as long as that large .84 A/R turbine housing doesn't slow you down.

 

Thanks again... will let you know the diff in power between the diffs housings I got...
Cheers.
