CNC-laser cut stainless steel medium streetport porting template for 13B-Turbo engine, in 2nd gen FC RX-7s. Unlike other templates, the holes are already cut for you. Just spray or brush Dychem or other brand Layout Fluid on the porting surface, then scribe the port outline using the template onto the layout fluid stain. For shipping, please select USPS Priority Flat Rate Box ($8.10). The template is very light, but requires a large box to protect it from shipping damage.
