A full External Wastegate (EWG) set-up consists of a EWG up-pipe and a wastegate. The EWG set-up creates better turbo spool because it can utilize the exhaust gas more efficiently; however, the full EWG set-up can be a very expensive project if you are on a tight budget.
The EWG Block-Off Plate is a solution for the person not able to purchase everything necessary for a full EWG set-up up front. The affordable EWG Block-Off Plate is placed over the side exit to the wastegate. This allows the EWG up-pipe to run without the wastegate. Once the wastegate is purchased, the EWG Block-Off Plate can be easily removed.
GrimmSpeed’s EWG Block-Off Plate is made from 304 SS and comes with a V-Band Clamp to complete the install.
