Fuel question/performance question
New to the thread and the world of first gens. I have a '93 SCLB. When I bought it I was told the truck has big injectors but not sure what size as the owner before him did them. I had Oregon fuel injection build me a pump with a 40hp pin and a 3200 gov spring, 16cm turbo housing and the upgraded VP style supply pump. I plan on doing a bigger turbo, torque converter and input shaft. should I have my injectors tested to see what size they are so I can figure out the best turbo set up to run? Also can anybody tell me what cc of fuel my pump setup is capable of or would I need to know the injector capability also?

Welcome to DTR! Any reputable injection/diesel shop should be able to clean, re-pop and veryfy the flow capabilities of your injectors. It's money well spent being that injector size and quality are a big part of the equation in how a first gen behaves. The company that built your pump should provide a flow sheet so you can see what the pump is capable of. You'd have to contact them for that information.

You need to help us, help you. 
Before any of us can truly answer your question, you need to tell us how you intend to use the additional power.
- Weekday worker / Weekend warrior?
- Hardcore work-truck with occasional cutting-up from a stoplight?
- Full-tilt drag-racer?
- Grocery-getter with occasional boat to the lake?
Further, what transmission do you have: Automatic or Manual?
It matters.
Generally speaking, 350HP to the ground is fairly easy and inexpensive with our VE fueled Cummins. If yours is an automatic transmission, you'll do well to invest in a tighter torque-converter as the stock/OEM article is really sloppy. No need in a big-name vendor there. Just have yours tightened or used as a core to trade for a tighter one.
A general horse power number in mind will help toward building the engine for that goal. -> Spend the money wisely . . . . . once. And, just like anything else, speed/power costs.
How fast/quick/strong can you afford to go?
