RD4-150 Injection Pump


Out of Stock, Call For Availability


The RD4-150 pump is the standard for 4 plunger R&D injection pumps. With peak fueling in the 200cc@1400 range, and 150-160cc@2800, the 150 hits 400whp with no issue, with over 800wtq on tap. The biggest of the “Street” pumps, the 150 retains close to a stock timing curve, inlet pressure, and standard R&D pump idle levels, preserving maximum drive-ability for high end street driven IDI trucks. All RD4 pumps include a brand new hydraulic head assembly.

-Upgraded turbo setup, and head studs required, as well as intercooler (Ignore at your own risk)

-Factory turbo or converted PSD forged rods highly recommended.
