Got a Blown Turbo

[Machine]

So some dumbass comes into the shop last week, complaining of a check engine light, apparently came on after he changed the oil. Turns out, this was the first oil change the car got since new, and it has 35,000+ miles on it.

check engine light was for camshaft correlation if anyone was interested.

anyways; The motor and turbo were totally F'd in the A. and I snagged the turbo, as it was denied for core. It is totally F'd, like I said, but its interesting to see its design and size.

some Basic specs I can tell from the Outside:

Garrett Brand Turbo,
Ball Bearing, water cooled center section.

Exhaust is single scroll with a .4 AR, Compressor is .42 AR with integral bypass.

I havent got it appart yet, but when I do, Ill take some precises measurements for future reference; it should prove usefull in determining if a compressor upgrade is possible.

some other notes, porting of the exhaust housing, especially the turbine and wastegate discharge areas could yeild some noticable improvements when the boost/power levels are raised.


Ill keep you updated and try to load some pics here soon.

Nice! Be sure to take pictures. It will be interesting to see

Nice info

35,000 on a Sonic already?

reminds of a girl i know whose daddy bought her a Beemer. She said it was driving funny and didnt run smooth. so i pop the hood, nothing obvious. just for kicks i check the oil. None. Nothing. Completly bone dry. She put over 25,000 miles on the car and didnt check the oil, no regular maintenance... Daddy buys her a nice car and she cant take care of it.

maybe he mistook the engine oil for the tranny oil which your only supposed to service every 50,000 miles. lmao

I would be very interested in it to see if we can do something like we are doing for the 2.0L Ecotecs. With those we are using the stock exhaust housings, machining them to accept larger center cartridge and compressor housings. We end up picking up 60-70hp at the wheels doing it. :banana:

If you would be willing to have us take a look at it, shoot me over a pm.

Thanks!

I am glad you snagged a turbo for measurements.

I see everyones excitement for getting bigger and better HP numbers.

My only concern is how much the internals of this motor can withstand. I mean its no 2jz in terms of stock durability but I am hoping the internals are good for at least 300 whp.

Reason I am concerned is everyone is happy with their 175whp for now, but soon (and it will not take long) people will be pushing the 250/300whp mark, especially if were getting 25-30whp of a simple "tune".

Food for thought.

I'm super happy with the billet batmowheel turbo (66/71/14) I have in my diesel dodge. It's such a badass compressor wheel, spools like stock (so light) almost yet flows enough to support 850rwhp and 2000ftlbs I cant push it that hard with what I have yet. But one of those wheels from bullseye performance (they make bolt in compressor upgrades) and maybe port the waste gate? It will be very interesting to see the bottleneck and how far we can push them.

Some Pics finally

Had to set it next to my Rx7's turbo setup.

I though Honeywell supplied the turbos to GM for the 1.4!
Thanks for the info.

Why would you not do a oil change in that length of time?! Jeez

 

[Machine]

I believe garret is owned by honeywell.

 

[TIEfighter]

That's why I don't have a turbo. Causes you to forget to change your oil because you think your car is too fast Just kidding. But for real that is stupid not to change your oil at that many miles. Especially since most of the dealers give you your first oil change for free! It would have costed that person an hour or two of their time for the first oil change. Cool pics of the turbo though!

 

[River_Rat]

And this is why I opted to buy a new car vs used: "Sure, I performed all of the preventive maintenance as per the owners manual, changed the oil and filter religiously every x000 miles, drove it like a little old lady, but only on the highway when the sun was shining."

 

[CoHPhasor]

So here's the real question:

Was this an automatic or manual?

I ask because alot of times manual turbos are larger than autos.
Autos idle higher than manuals so you don't have to wait as long for spool and automatics usually don't handle hp as well as manual trannies.

As an example, my 91 300Z TT has a larger exhaust housing (AR) because it's a stick than my buddy's automatic TT.

(My 1.4L auto is still in the early order stage, not too late to swap to the 5sp!)

 

[rdss]

If you get the 1.4t manual it will be a 6 speed not a 5. I prefer manuals myself.

 

[CoHPhasor]

tomato, tomato.
5sp, 6sp, we'll just call it a manual. ;-)

 

[rdss]

Tomato, potato...lol it has an extra gear. But yeah, not a big deal, just letting you know what you will be getting with the 1.4t and nothing else.

I'm interested in the BBPV. Take it off and get pictures. I want to figure a way to make this have an atmospheric BOV. What sensor is between the BBPV and the TB? I couldnt see it from any pictures of the motor online. Is there an air metering sensor hidden elsewhere on the charge piping?
