Precision Turbo Upgrade On A 1987 Buick Grand National Turbo Mounting Brackets
|
We mounted (in-line between the boost source and wastegate actuator) the RJC Racing Hybrid Boost Controller on top of the new Precision Turbo. RJC developed this boost controller so you can run a larger turbo and experience less lag as well as eliminating boost creep. We installed it according to the instructions (adjusting the wastegate actuator and bypassing the factory boost solenoid). On our testdrive the boost came in noticeably sooner, smoother, and at a lower rpm as advertised. $55 well spent! View Related Article
