I am going to be doing a set of twins and I was needing some recommendations for a bottom turbo. I know of the s400 and the ht3b are there any others I could use. ALso I have read that the s400 spins the opposite direction from the ht3b does it matter which one I use.

Could I also get some price quotes for either one of them new or used.

The S400 would work nice if your looking for working or towing twins, the S480 would be ideal for competition or Dyno results.

What are your goals with the truck?

Borg Warner K31 is another turbo you could use. The "big brother" or industrial injection phat ******* turbos are two VERY big bottom turbos. The spinning of the turbos will effect the plumbing of the system. I see more and more people start using S400 over the ht3b since they claim it can move more air.
