any opinions on the cobra stage 4 twin turbo kit for a 92

 

Who makes that?

Twins are great, but you're looking at thousands of dollars in supporting modifications to use the twins to their potential.

 

PDR and Begle's right your gonna need ALOT of mods to be able to fully utilize this much air flow....



PDR Diesel Performance: Cobra Stage 4 Twin Turbo Kit - (Custom S300/HT3B) 1991-1993 Dodge Cummins

 

I run the Cobra Stg 1 and can come up with right at 405HP / 840ft/lbs (#2 uncorrected) using DDP4 (regular) injectors and the typically tweaked 12mm VE. With a heavily PDR ported head, Banks after-cooler and TwinRam feed horn, 3" plumbing, etc, I still see 60psig boost at the intake log. Adding a little W/M has things go to over 65psig boost with 405HP / 900ft/lbs and the mess still struggles to go above 1300*F.

As others have pointed out, you're gonna have to step into the BIG league to realize the potential of the Stg 4.
