I have an automatic with mods in sig. Looking for a bigger turbo and maybe injector combo for the smarty. Its a daily driver looking for reliability. I tow maybe once a month with nothing over 8K lbs. Thinking about silver 64 with small injectors (50hp). They also have a 62/74 turbo but cannot find any info from someone running it. Or would a sb 62 without injectors be a possibility. Any help will be appreciated

Silver series turbos are a little too big on the turbine side for what you are wanting to do. If you want to stay with the industrial products, look more at the phat shaft 62 with stock injectors and the SPS 62 if you get the 50hp stix. There are a ton of other choices out there too that would be better than the sliver series.

Id go with HTT ss series, 62/71/13ss or 65/65/13ss, the sb 64 will be way to big with only 50hp stix, especially towing

Yeah I agree, with a Auto a 64 maybe to big, I'm a lil higher in altitude, "around 5800 to 6000ft" but my 64 with my 6 speed is real touchy with surging a auto would be a nightmare.

I agree with Hintz.. One of the 62/xx/13ss HTT turbo's should net you good street power, but still spool well with the auto when towing, especially with the small stix.

If i run the sps62 from industrial injection is a new down pipe required and a boost fooler. I have heard from one place to another that it is not and is required.

You don't need a new down pipe but you'll need to get a wastegate sensor fooler.
