There's a rather large junkyard that's going to be having a huge sale on saturday that I plan on going to.. Things are going to be rediculously cheap, but I still need to justify my making the trip I'm going boosted this winter with my N/A block, so I plan on grabbing anything that will help my quest this winter.. . Fabrication is not an issue, so the direct bolt on isn't an issue, as I don't even have a turbo manifold yet.

My goal is somewhere around 250 at the wheels for now, while being very streetable, but maybe a bit more later.. I'm not planning anything too crazy on this setup, and I plan to build a motor later if (when) I want more

So, which stock turbos would work well for our cars? I do plan on grabbing anything I can off of a turbo II, if they have one...

 

Almost everything out there is too small. Manufacturers tend to use very small turbine sides for quick response on piston cars.

Abotu the only turbos I would be looking at are from diesel trucks, which are often some variant of the T4. Also, the turbo from the Grand National seems to be workable, but of course they are rare.

 

I guess I should have have figured on that.. I'll look for a GN, but I doubt it would be there.. Any specific diesel trucks you can think of? I don't think there will be many there that wouldn't be beat to hell and back, though, as people really don't let go of GNs in good shape, nor do any desiel trucks I can think of normally make it to the bone yard.

Thanks for the info, Aaron.

 

GN's run stock T3's - still too small.
You need to get your hands on BIG diesel rigs (semi's) or Caterpiller bulldozers / tractors to get the big stuff.

Anything stock on an automobile will be not worth it; they are all too small.

Now's if we're talking TWIN's, that's another story!
I don't suppose you can get your hands on a pair of S14 / S15 turbos?

I don't know off hand. Up until recently, I didn't pay much attention to the diesel turbos (I'm looking for one to make a turbine engine).

 

Good point, I could get a set of twins.. . anyone know anything about the stock 3000GT VR4 twins? maybe a set of those or something?

When you say S14/S15, you're talking about the Silvia's turbos, right? If I can find them, I'll grab em.

So if I can find a big diesel rig, it will be around the right flow for a rotary? If I see one or two, i'll grab the turbos..

This sale is going to be awesome: 20 bucks to get in (it's a you-pull-it place), and 2 dollars for any part you remove

 

Still too small.


Yep.
You live in Japan or something???

That's correct.
Most likely the compressor side will be sized right, but the turbine size might be too big...

I'm also looking for a diesel turbo to use as a propane turbine, or maby a wood burning turbine engine so many options.

 

Nah, I just called it a silvia, because I didn't think the 240s came turbo'd in the states, did they? I'll check under the hood if I see any..

The large A/R of the diesel turbos is what I'm worried about.. I really don't want a lot of turbo lag, but I should be able to tune around an excessive A/R with my MegaSquirt.. I think

 

Uh...no.


-Ted

 

HOLSETT. That's about all you need to know, you can get a T66 that'll work pretty well for most engines and be loud as all hell for around $600.

 

Holsett? That's a hybrid Garrett, isn't it? I don't think I'm going to find that in a junk yard, but I will be looking for it if I don't find anyhting acceptable in the bone yard (and it doesn't sound like I will). I was looking at a BNR hybrid, but I'll check out the Holsett too, any idea where I can pick one up?

Ted - Remember, not only am in mainland America... I'm in the Middle-of-Farkin'-nowhere I'll be surprised if there's another Rx-7 or two in there, let alone a turbo 240 Stupid PennsylTucky...

 

where is this junkyard, is it in the ohio direction of where you are?

 

I was thinkin the turbo off the 80's Tbird would fit....but it is too small..........


Hmmmm Would the turbo off a Mazda MX-6 be suitable......?

 

This one is is actually on the other side of the state (near Allentown).. The junkyard is actually three different ones.. It's called Harry's You Pull It Http://http://www.wegotused.com/ . So it would be a REAL trek for you in Ohio.. it's only about a 2ish hour drive for me..

 

Uhh... The silvias are single turbo.. and they are a modified T25... I wouldn't bother with those even if you can find them...

 

T28's on S14's+.
Supposed to be "semi" BB centers?


-Ted

 

s15 canme witgh a stock t28 bb

 

hmm i have access to a late 90's dodge deisel(I browse raise)

 

The stock SR20 turbos have a lot of plastic involved too. I try and avoid plastic turbos.

 

Ahhh Aaron how big of a turbo do you need. I can get some really big ones. Where the compressor inlet is bigger than my hand. I am not sure of the make. I think a couple a holsets, and a few garrets, some others.

now for the subject at hand. Look for a old detriot diesel powered trucks most were super and turbo charged. The turbos dont have waste gates but can push around 35psi at an engine speed of 2500RPM I am pretty sure, I will check all the numbers at work tomorrow.

And if you are looking for a ball bearing turbo. Check old isuzu powered trucks and some cummings engines. Hopes this helps

dont use 3000gt turbos. they are small.

the turbos i would use are from mercedes cars, volvo's, and trucks.
also, a junkyard turbo setup is just that, a junkyard turbo setup. tbird 48/60's are good, and stuff.

go check out homemadeturbo.com they have tons of good junkyard turbo info.

 

I was also thinking about a Mazda MX-6, I just sold one online for 150 bucks. but it was on the small side, prolly to small.

 

Not worth it...
They sell brand new T3 "60"'s for $150 on eBay.

what would be the effect of using a smaller turbo? I don't see how it would be a hinderence with low power applications.

I'm looking at using a 60 CT26 from a MKIII Supra. The turbine is a "little" smaller, but with my application I can't see it being a problem.
