twin turbo
 

will a ht60 form a n14 work for bottom turbo for a tow rig top turbo will be a hx35

Yup, sure does. just like a 3B but uses an S400 style comp outlet. So if you buy a kit, be SURE they know you have a HT60!:c:

what kind of injectors should i get. i also can get a turbo for a 60 series Detroit it looks a little smaller

you should be able to run 600rwhp with those if done right.

The Detroits used a few different sizes, but in design are very similar to an S400. Look for the A/R # stamped in the exhaust housing and measure the comp inducer( small side of the intake wheel) in mm for a better comparison.
