Junkyard Turbo Question
Ok so i've searched the tech and other forums too and seem to find plenty of threads about a junkyard motor with a nice shiny new turbo. I can learn more than I can remember about what heads off this truck or the cam sensor from this to that year etc etc. but cant find a good list of junkyard turbos.
Near me the local pull a part sells turbos of any size off any vehichle for 55 bucks.
Now, compared to 350 for new chinese turbos as cheap options or new garrets/borgs for 650 on up... 55 bucks is a steal
I was wondering if anybody could give me some a *recommended* turbo spec for my motor and maybe i can search for a turbo off of a diesel truck or something to get as close as i can...or if anybody has pulled one and used it on a similar build, fill me in please!!
The motor is a 5.7, forged bottom end, port and polish heads with close to 10:1 compression
I know this is a little high for boost but the motor was built to originally be a street motor with possible spray at the track. Now that I see people near me, and on these forums getting to enjoy the boost all the time, I wanna try too, but on a tight budget i can't really change now to lower compression. Fab skills shouldn't be a problem but the $$ will keep it tight
I want to run about 6 lbs (maybe 8) on the street and kick it up to about 11-12 at the track.
Thanks for any advice you tech gurus might have!

By tight budget i don't mean im re-using paper plates or anything
Just saying if I can get a turbo for $55 that will work it sounds a hell of alot better to me than a $700+ turbo

its very hard to find an decent stock diesel turbo to make 500+ in my opinion.
they are also large, the flanges and more are usually non standard, they are rusted and blown most of the time etc
ive used an actual junkyard turbo, found one in the 70mm range, maxed out at 550whp and then promptly blew up.
in my opinion you are better off getting a gt45 68mm if you can fit it or going with an on3 unit as they have a smaller footprint if you are pressed for space

Not saving yourself much money IMO. Very doubtful you'll find a turbo large enough for your application. And if you did, the chances it was in good useable shape would be even smaller. By the time you cleaned it up and rebuilt it you could have bought a china turbo better suited to your setup.
The $222 shipped gt45 turbo would work better than most of the JY units out there. Seems to have a good track record durability wise and performs well.

I was looking into a turbo from a late 90's 7.3 powerstroke
the specs are
STOCK GARRETT TP38
Compressor wheel inducer diameter: 59.87 mm (60 mm)
Compressor wheel exducer diameter: 80 mm
Compressor housing A/R: 1.10
Turbine wheel inducer diameter: 76.2 mm
Turbine wheel exducer diameter: 69.84 mm (70 mm)
Turbine housing A/R: 1.15
Does this seem like a good fit...to me the large ar seems like it would be slow to spool but would the size support decent hp?

gt45's come in different A/R sizes from what I can tell and also widely different compressor wheel sizes.
I find them from 50mm to 68 mm for reasonable price
I know a new turbo will be the "best" option but I would really like to do a junkyard turbo.
This way, if i get a $55 turbo and decide I don't like any part about it on the street or at the track, or say i have issues with an oiling system and take out a turbo, etc.. im only out that much.
If i decide i do like it and want to upgrade, i always can later to a better suited turbo.
But, until that time that i decide one way or the other, is there a turbo off a diesel truck that someone could advise me towards that won't be terribly ill suited to my setup

Again, if taking out a $222 turbo will break you then the turbo game really isn't suited for you. I understand the budget build completely. It's taking me a long time to search for deals on certain parts and find certain parts used to save money here and there, but why cheap out on the whole reason your going boost, the turbo? I know incase something happens but again it's 222 and honestly if your doing a turbo setup that's less than 60 or 80 lb injectors that your going to need for your setup and in the scheme of the whole build that's really not much.

If you got 2 junk yard turbos you could probably get away with it. But a single really isn't a good choice imo. If you could get a couple evo 16g's. Or maybe a set of holset hx35s or hy35's from a dodge diesel truck.

Holset turbos are going to be your best bet for junkyard turbos. An H1C/HX35 or larger Will do 450whp on a single.
I know it's 55 dollars, But there's a lot of factors at play here. For example, there's a 70% chance the turbo is trash. There is also the flange issue. Most of these use proprietary downpipe flanges, and they're internally gated. That's extra money spent on a downpipe, and even more If you ever switch turbos.
Get the $222 dollar GT45. It has a 4" downpipe v-band and is physically the same size as the sx400 series Borg Warner turbos, which gives you LOTS of possibilities for upgrades with very little work involved.
