• i just got a T4 turbo from a friend, he had it on his detroit 4-53, and it never worked right on his truck. the seal for the cold side was NOT THERE. i imagine that was the reason it made no boost. anyways, is there any way at all that a 1.6 w/ a VNT already installed could spool a T4 in a compound setup? or should i use this one on my 2L 16v turbo engine? or am i just barking up the wrong tree? trying to fit a T4 to such a small engine?
  
  heres a couple pics of it.. hopefully one of you guys can tell me a little more about the turbo
  
  
  
  
  
  
  
  
  
  thanks for looking..

• see if there are any other numbers on it really all u can tell from what uve shown is that it is a t4 with a .60 a/r compressor housing, the a/r of the compressor housing means basically nothing.  the turbine housing sometimes has the a/r cast in the inlet similar to the way the compressor is.  unless theres a part number on it you'll have to take the compressor housing off and measure the wheel to figure out what u have.  measure the inducer and exducer on the intake side, i wouldn't worry about measuring the turbine, especially cause the turbine housing a pita to take off.

• also that turbo looks insanely huge    i can tell u already that it has a 99.99% chance of not working on a 1.6 ever haha.

  i knew it was too big for a 1.6..
  
  but a 2L 16v, might be able to do it?
  
  i compared it to a HX35 yesterday, and its MUCH smaller than that.
  
  IIRC 2.16" inducer, and 2.56" exducer on the cold side.. hot side is pretty close to the same specs. not far off atleast..
  
  ill measure the wheel again here in a bit..

• yeah not as big as i was thinking actually.  hmmm

  yeah not as big as i was thinking actually.  hmmm
  

  
  when i got it, i thought it was HUGE, but then comparing it to other T4s, im starting to think that its not as big as i once thought..
  
  it was off a 3.9L 4-53 Detroit diesel.. its not original tho, because 4-53's never came turbo charged..
  
  once i started spec'ing it out a little, i decided its not as huge as i thought..
  
  2.155" inducer, 2.755 exducer. (cold side)
  
  
  
  
  
  anyways, i made a gasket for the cold side housing out of a paper plate, and now it should be a good, useable turbo.
  
  this thing look too big to even use on a high revving 16v gasser?

• honestly using google i can't figure out what turbo that is, its actually not all that big tho.  its a 70mm 61 trim.  the inlet size is almost 55mm so its inlet is actually slightly bigger than your typical 50 trim t4 which is about 54mm i think.  the large size of most(not all) t4's is 76mm which generally means it is capable of creating more pressure than your turbo.  judging by the inlet size alone i would guess the turbos capable of over 400hp and it would probably work pretty well on the 16v depending on what turbine housing it has.  and actually it may work pretty well as a compound on a 1.6 since its not nearly as huge as i had thought originally. its hard to say tho with out knowing what it actually is.

  i couldnt find any specs or numbers on the exhaust side.. its kinda a mystery turbo..

  I sent these guys an email about my turbo and they gave me a response. As long as it is aftermarket they said they could usually give maps and info. If it is an OEM application they don't get as much stuff. Would be worth a try.

• That is a Garrett correct? From what I saw that is why I gave you the info above.
• #10 by RabbitJockey on 06 Dec, 2011 08:36
• i'm think its a t04b v-trim, the exducer is the right size to be one, and i've seen the v-trim inducer listed as 2.12" or 2.18"  so perhaps it was measured wrong by a few 100ths?  if that's what it is then it'd be a pretty good turbo on your 16v depending on your power goals.  t04b's are pretty old theres alot better turbos out there but when you're talking about free stuff here, then its a damn good turbo haha.  just depends what exhaust housing it has for whether or not it spool up nicely on your abf there
• #11 by RabbitJockey on 06 Dec, 2011 08:48
• ok here it is plotted for 400 hp @6700 rpm @ 20psi, looks ok, this is under pretty optimal conditions tho, and i don't really know much about plotting the 16v, but i made this based on other peoples dynos numbers and what psi/rpm they did it at.  the third dot back from the right is where peak power would be, and its in the 65-70% efficiency range, which is alright but not ideal
  
  
  
  
  as you can see a 50 trim t04e would be alot better, actually any t04e you look at looks much better.  and thats with out even going into all the new gt series awesomeness

  my calipers are not perfectly accurate..
  
  yes, im sure this turbo is ancient.. it came off an old detroit diesel. dunno what the original application was tho..
  
  definitely a garrett T04.. only says AiReasearch on it, so im assuming its fairly old..
  
  no number plate on it anywhere as to give more info about it, just the few useless numbers on the edge of the compressor housing..
  
  i was kinda thinking this would be a turbo for my 16v, rather than for the turbo. i figured ANY T4 would be too big to spool with a 1.6D
  
  im not going to be running 400hp with it tho.. power goals are around 200-250hp or so. i dont wanna go too wild with it.. nice to know it will support all the HP i would ever want tho..
• #13 by RabbitJockey on 06 Dec, 2011 19:18
• Spool up mostly depends on the exhaust side. Now that Ive seen the map I don't think it would do 400 maybe on the perfect day if would but the efficiency range is pretty narrow. If 250 is your goal I recommend a 60trim t3 but I cant tell u what exhaust size to get probably a .63 will do it but I'm no expert. The t3 off a turbo ford would probably do the trick. But if I had an abf it would have a t04e 50 trim bolted to it or a super50. Cause they can make mad power yo. But as far as the v trim goes it could work but I'd ask on vortex first especially since the exhaust ar is unknown like I said Im no expert either
• #14 by RabbitJockey on 06 Dec, 2011 19:20
• Also if u really don't want more than 300hp the 60 trim t3 is gonna spool nice and make good power for u
