What's best clutch and injector pump for my 2001 ?
.it has 45 hp injectors, super B turbo, air dog 100, blue chip fuel management adds 100hp.

 

As far as VP's go, make sure it come from one of the places on the list. They are Bosch certified and have the necessary flow bench to do them correctly.
The list:

Midwest Fuel injection
Industrial Injection
O-F-I (Oregon Fuel Injection)
Jasper Engines
Diesel Fuel Injection Rebuild Center
Central Motive Power
ProDiesel
Diesel Forward (Diesel Injection Service)

 

The two most commonly used clutch companies used by members are Southbend or Valair. There's a few others out there rarely used too. I'd call those suppliers up and personally ask them what clutch they think is best for your application.

As for the fuel injection pump, cougar provided the appropriate list. I'd just suggest staying with a stock level VP as any VP built to create more hp will only lessen reliability, and the amount of hp it offers is only minimal.
