Garrett GTP38
 

I cant seem to find any real info on this turbo... We've had this turbo sitting at our shop for quite a while off a 7.3L powerstroke diesel... I've had a local rx7 shop tell me that its a worthwhile upgrade. Any one happen to have any experience with these turbos, or some kind of info?
The motor is a ported s4 13bT....

ok so i finally found a map, however it doesnt have the efficency levels posted on the graph...Is there a way to find them using the map? This is the link to a upgraded model, but shows the original aswell.

So it would be the red lines on the graph...

Looks like it may work afterall? Any input would be great!

55 pounds per minute makes approx 400 rw on a 13b

So what do you suppose if the turbo flows around 59-60 lbs/min. Do you think you would be able to get around 415+?

Compressor map
 

Does anyone still have a compressor map for a GTP38 turbo?

It is no longer appeared in Garrett catalog.
