The RD4-130 is the newest pump in the R&D lineup. For years there has been a gap between the 110 and 150 pumps (between 300 and 400whp), leaving the non-turbo connecting rod engines without optimization. The 130 fills that role by providing fuel for the 350whp level, and keeping the non-turbo bottom ends safe. Has all the highest upgrades of any R&D pump. All RD4 pumps include a brand new hydraulic head assembly.
-Upgraded turbo kit required
-Head studs required
