I'm wondering what size Delivery Valves i should use in my 1994 dodge cummins 5 speed, gauges (pyro, boost, fuel pressure), 4'' down pipe with 5'' from down pipe back. This truck is a daily driver and pull a trailer with it once sometimes twice a week. I'm going to be buying a 14cm non-wastegated turbo exhaust housing in a couple weeks.

sorry forgot to add that, I have a #0 fuel plate, plates pushed forward, and starwheel is turned.

 

keep the stockers or 181's

 

What about injectors? i've been told those are more important then delivery valves.

 

got a set of 181s layin around, $100 bucks shipped if youre interested

 

thats a pretty good deal but i think im gonna get injectors before i get delivery valves. thanks though!
