Turbo application question
 

Is the turbo design below for quick spool like a K27 7200 or for a more high revving application like K27 7006?

This is a 3ldz 5222-970-3100 turbocharger with a big 2.5 inch inducer comp wheel. It has been glass bead blasted, shot peened, flash honed on a sunnen honing maching, slow speed balanced on an autotrack 2000, assembled with a new service kit to factory specs, then high speed balanced on a turbotechnics vibration sorting rig (VSR). has 1.79 turbine housing. comp housing is semi polished in a media shaker machine. It has a 360 degree thrust bearing and a bigger shaft than k27 for more thrust load.

thanks,

That is a stock 1986-1989 930 turbo part mumber.

Turbo Application
 

Yes it is a 3ldz housing with modified components. I wanted to know what these modification would do to the performance of the turbocharger as compared to a stock 3ldz or a stock K27.

Thanks

did you bought it on ebay?

Turbo Application
 

Not yet but I am very interested. I need to know the application it is designed for before I pull the trigger.

turbocharger modification
 

Any additional information will be greatly appreciated!

Thanks,

3ldz has a small very old design turbine housing compard to k27 7006 and it's old and discontinued now too.
Stuffing a bigger compressor wheel into it and making it into a hybrid will probably slow the boost buildup a little because of it's weight and drag and it may make a little bit more boost overall than a stock 3ldz but it's old obsolete whatever compared to whats available now from Garret.

Even a k27 7200 or 7006 would be better.
Being in Illinois and upgrded with a 360 degree thrust bearing I wonder if it came from Durabilt turbo.

The small housing allows the bigger wheel to spin up faster, mine starts to lift the needle @ 2000 rpm's. 1 bar by 3000 and pulls to the top.

Great improvement and still looks stock for those that care.

The compressor wheel is made by schwitzer. That was the reply to my question.

Ask the seller to answer your question.

I asked him but no reply as of yet!

Thanks for the input. This is what I thought the larger compressor wheel would do. More pressure at lower RPM but due to the small housing I thought it might be restricted at the top end. Currently the motor is a stock 1976 3.0 turbo. I thinking this should work well for this application.

JFairman, any additional input on how you think this will work ...or not work?

I won this. Kind of a risk......420 bucks...we'll see. in the middle of a trans rebuild clutch package oil leak fixing engine out project. if it works, cheap rebuild/upgrade over my old 25 yr old ldz until a proper turbo-cam-wur project.

Thanks

Sent you a pm...356
