Turbo Flange T4
so now that the parts list is disclosed... what should I change or upgrade. And power numbers to be expected... on sure this is a worn out subject. But can't learn If u dont ask

 

Is that the "OG" gt45? they tap out around 550 wheel in my experience.

I'd bump to the 7875 were it me. Makes for a really fun street car.

 

its a ebay turbo ... would everything I have support the 7875

 

yep. some little stuff like needing the angled oil drain, the compressor outlet is 2.5" are different, but and the turbine outlet is 3"

I put my old 7875 on my friends' bone stock 5.3 to replace his gt45 and it turned a fun car into an absolute blast.
