it looks more like the t04b 55 trim, they also call it the T5/6 and there's no flow chart published for it.

 

When i get the Turbo i see if the tag is still readable.

 

Well, a look at the surge line tells all. There is a little bit of difference.

Comparing a stock cam stock cast mani 4G63 to a D16 or stock cam LS is probably fair, but if it's got any of the VE-increasing goodies on it like a merge collector manifold and cams then that turbo would probably work pretty well. 4G63 heads pull some impressive flowbench numbers but the valves are so shrouded they end up flowing a lot less in the real world.

No clue as to whether or not this is the same turbo, just an opinion.

 

Go for the .63, imo it spools at a good time on a ls, for street use that is....

 

 

Update i got the T04b Today it is a V-Trim Compressor .60 A/R with a .63 Hot Side and a stage II Turbine wheel. It should get the job done

 

sounds like fun, new toys always makes my day, except when they send you the wrong fuckng one, but thats a whole diffrent story
