Twin turbo set up
 

So I just came into a 68/88/14 industrial injection turbo for free. I have a quadzilla adrenaline and 250hp injectors right now. I understand that as a single this will be redic laggy correct? If I were to twin it what would you recommend as the secondary?

To add a second turbo to that you will need something in the 88-95mm range ideally in my opinion. We have a truck here at the shop with that same turbo with a 93mm billet wheel primary charger. Its in this video at about the minute mark. This truck has IIS 5x20 injectors, Colt Stage 4 Cam, IIS Dragon Flow 13mm P-Pump, Dueling fass 260HD Lift Pumps and some more. And it did 993 at ATS's dyno day!

Couldn't I use that as the primary though and use something smaller that will spool faster. Don't want to P Pump yet.
