One of the best ways to clean up your Supra, SC300, or other 2JZ swapped car's engine bay is to do a makeover on the factory valve covers. Most modified 2JZ's are running a catch can setup off the valve covers to allow the crankcase to breath easily.
You will send me your GTE valve covers, and I will remove the baffles, drill and tap the covers so the baffles can be easily replaced using bolts rather than the OEM rivets. This will allow future servicing of the covers, or future color changes, etc without worry.
The covers will then have AN fittings welded onto them. The covers are then sandblasted and powdercoated. I can powdercoat them in pretty much any color, some custom colors may require additional cost.
